Overview
What matters first
DUI, DWI, OWI, and similar impaired-driving laws are highly jurisdiction-specific. Penalties depend on blood alcohol content, prior history, age, injury, refusal rules, and court outcomes.
National guide
DUI Laws
Review official state-level information on impaired-driving penalties, suspension rules, reinstatement steps, and related requirements.
Prepare
Documents and details to confirm
- Citation, court documents, or administrative order
- License and case-identification information
- Proof of program completion, ignition interlock, or insurance filings if required for reinstatement
Typical steps
How the process usually unfolds
- Separate court requirements from administrative motor vehicle actions, because both can apply.
- Check official guidance for suspension length, reinstatement fees, and mandatory filings.
- Do not rely on generalized summaries when deadlines or hearing rights are at stake.
FAQ
Common questions
- Does a DUI arrest automatically suspend a license?
In some jurisdictions, an administrative action can begin quickly after an arrest or refusal, but the process differs by state.
- Is reinstatement the same as paying one fee?
Often no. Reinstatement can also require insurance filings, program completion, hearings, or interlock compliance.

Alabama DUI Laws
Alabama's official DUI materials are strongest when read as a conviction-and-license-consequence system rather than as one flat first-offense chart. ALEA's driver manual says it is unlawful to drive with a 0.08 BAC, to drive under the influence of alcohol or impairing drugs, to operate a commercial vehicle at 0.04 BAC, or for drivers under 21 and school-bus or daycare drivers to operate at 0.02 BAC. The state then escalates quickly. A first conviction normally brings a 90-day suspension, but ALEA's ignition-interlock page says a first conviction under 0.15 BAC can have that full suspension stayed if interlock is elected, while a first conviction at 0.15 BAC or higher triggers mandatory one-year interlock. Repeat convictions move into one-year, three-year, and five-year revocations with longer mandatory interlock periods, and ALEA separately publishes higher reinstatement costs for alcohol- and drug-related cases.
Alaska DUI Laws
A useful Alaska DUI page should start by separating the arrest-side DMV case from the criminal court case. Alaska's official sources say one DUI incident can produce both an administrative revocation and a court revocation, and the DMV action can still stand even if the criminal case is dismissed. The most practical Alaska details are the seven-day hearing deadline on the notice, the 90-day to five-year revocation ladder used by both DMV and the court, the fact that refusal is treated as its own offense and blocks limited-license access, and the long-tail reinstatement rules involving IID, SR-22, ASAP treatment, and new testing.
Arizona DUI Laws
A strong Arizona DUI page should explain that one arrest can trigger at least two different tracks: MVD administrative action against driving privileges and the criminal court case. The most useful Arizona-specific details are the 30-day temporary permit, the 30-day deadline to request an administrative hearing, the difference between a 90-day test-result suspension and a 12- or 24-month refusal suspension, the restricted-permit versus SIIRDL split, and the way conviction-based IID, Traffic Survival School, SR-22, suspension, or revocation requirements can stack on top of the arrest-side action.
Arkansas DUI Laws
A strong Arkansas DUI page should start by correcting the terminology. For adults, Arkansas' main alcohol-driving offense is DWI under section 5-65-103, while drivers under 21 face a separate underage DUI framework with a lower alcohol threshold. The practical Arkansas details are the state-published suspension ladder for adult DWI, the separate underage suspension ladder, the commercial-driver 0.04 alcohol threshold in the hearing materials, and the fact that reinstatement is driven by education or treatment, a Victim Impact Panel, ignition interlock, fees, and sometimes full retesting after revocation.
California DUI Laws
A strong California DUI page should explain that one arrest can trigger two separate tracks: the DMV's Administrative Per Se action against driving privileges and the criminal court case. The most useful California-specific details are the 10-day DMV hearing deadline, the 30-day temporary license window, the sharper penalties for chemical test refusal, the difference between first-offender and repeat-offender IID options, the requirement to use a state-licensed DUI program, and the fact that many final outcomes still depend on the exact court charge, injury status, prior history, and plea or trial result.
Colorado DUI Laws
A useful Colorado DUI page should start by separating the DMV case from the court case, because the state says those paths operate independently and the license action can move even if the criminal case does not. Colorado also does not use one flat BAC rule. CDOT says 0.05 BAC is the DWAI level and 0.08 BAC is the DUI level, but officers can still arrest for impairment below 0.05. The most useful state-specific details are the seven-day DMV hearing deadline, the under-21 alcohol rules that start at 0.02 BAC, the way refusal and 0.15 BAC create Persistent Drunk Driver consequences, and the fact that a fourth or later impaired-driving offense can move into felony territory.
Connecticut DUI Laws
Connecticut DUI law works on two tracks at once: DMV administrative action after a failed or refused chemical test, and the separate criminal court case. The practical rules are the BAC thresholds of 0.08 for most drivers and 0.02 for drivers under 21, the short 7-day deadline to request a DMV Administrative Per Se hearing after the suspension notice is mailed, and the fact that restoration usually turns on an ignition interlock device rather than on a long no-drive period alone. On the conviction side, Connecticut's default license consequence for a first DUI is 45 days of suspension followed by 1 year of IID, while a second conviction within 10 years means 45 days plus 3 years of IID and a third within 10 years leads to permanent revocation unless later reversed or reduced.
Delaware DUI Laws
A strong Delaware DUI page should explain that one arrest can create two different tracks: DMV's administrative revocation process and the criminal court case. The most useful Delaware-specific details are the 15-day temporary license and hearing deadline, the difference between a probable-cause revocation and a chemical-test-refusal revocation, the way BAC tiers of `.15` and `.20` increase conviction-side revocation periods, the narrow eligibility rules for the First Offender Election, and the fact that Delaware's IID program is now built into both diversion and post-conviction paths rather than treated as a rare hardship option.
District of Columbia DUI Laws
District DUI cases run on two related but separate tracks: the criminal case in court and the DC DMV revocation process that starts from the Order or Notice of Proposed Revocation. The practical District rules are the 0.08 alcohol threshold for most drivers, the 0.04 threshold for commercial drivers, the short permit-hearing deadline after the revocation notice, and the fact that current DC law routes impaired-driving offenders into the Ignition Interlock Device program instead of treating revocation as a simple wait-out period. DC's current public materials also make a sharper repeat-offense distinction than many generic guides: a first DUI conviction ties to a six-month revocation period, a second to one year, a third or subsequent to two years, and a third conviction within five years can become an indefinite revocation until DMV reinstates the privilege.
Florida DUI Laws
A strong Florida DUI page should explain that one DUI arrest can create two separate tracks: the immediate administrative suspension handled through FLHSMV and the later criminal conviction consequences. The most useful Florida details are the 10-day temporary permit, the need to use that same window for review or hardship strategy, the six-month or one-year suspension pattern for unlawful alcohol level, the one-year or 18-month pattern for refusal, the 30-day and 90-day hardship waiting rules, and the conviction-side FR-44, DUI school, IID, and revocation rules that can continue long after the arrest paperwork is over.
Georgia DUI Laws
A useful Georgia DUI page should start by separating the arrest-side Administrative License Suspension from the later court conviction consequences. Georgia DDS makes the practical timing rules unusually concrete: after a DUI arrest, the driver generally has 30 calendar days from the serve date on the notice to choose an ALS response, and doing nothing can let the suspension begin on the 46th day. The other Georgia details that matter most are the 12-month first-offense suspension with reinstatement after 120 days, the one-year implied-consent refusal suspension, the under-21 .02 rule, and the ignition-interlock and clinical-evaluation requirements that grow quickly on repeat offenses.
Hawaii DUI Laws
Hawaii's DUI law is best explained as an OVUII system with separate court sentencing and ADLRO license-revocation tracks. The adult offense covers impairment by alcohol or drugs and per se alcohol at 0.08, while Hawaii separately penalizes drivers under 21 for operating with a measurable amount of alcohol. On the criminal side, a first OVUII with no prior conviction in ten years brings a one- to eighteen-month revocation, ignition interlock during the revocation period, substance-abuse programming, and jail, community service, or fines. On the administrative side, ADLRO generally issues an alcohol-case review decision within eight calendar days, requests made within six days of mailing keep the statutory fast-hearing schedule, and refusal raises the revocation ladder to two, four, or eight years. Hawaii also treats 0.15 as highly intoxicated and escalates both court and administrative consequences, while habitual OVUII becomes a felony.
Idaho DUI Laws
A useful Idaho DUI page has to separate three different problems that people often collapse together: the criminal DUI case in court, the administrative license suspension that follows a failed evidentiary test, and the separate court-ordered suspension for refusing testing. Idaho's practical rules are specific. The adult BAC threshold is .08 in a non-commercial vehicle and .04 in a commercial motor vehicle, under-21 drivers face separate .02 alcohol rules, an ALS hearing request must be made within 7 days, a first ALS starts 30 days after notice and may allow only the last 60 days on a restricted permit, and refusal suspensions do not allow a restricted permit at all.
Illinois DUI Laws
Illinois DUI law runs on two separate tracks: the criminal case and the Secretary of State's statutory summary suspension. The practical Illinois rules are the 0.08 BAC standard for most drivers, the 46th-day start for the summary suspension, the first-offender split between a 6-month failed-test suspension and a 12-month refusal suspension, and the fact that an eligible first offender must be at least 18 to use an MDDP with a BAIID. Illinois also keeps a separate under-21 zero-tolerance system for any trace of alcohol.
Indiana DUI Laws
Indiana's official sources frame this area as OWI, not just generic DUI, and the state separates arrest-side license action from conviction-side penalties. The Indiana BMV manual says operating with a blood alcohol concentration of 0.08 or more is a criminal offense, a failed chemical test brings a 180-day suspension, and a refusal brings a one-year suspension or two years if the driver has a previous OWI conviction. Indiana's current public safety guidance also shows that conviction penalties escalate quickly: a first offense can bring up to a two-year license suspension, a second offense brings at least 180 days up to two years, and a third offense can bring one to 10 years plus Habitual Traffic Violator exposure. If a driver is eligible to keep limited driving privileges, Indiana handles that through a court order for specialized driving privileges, with SR22 and possible ignition interlock requirements.
Iowa DUI Laws
Iowa's DUI topic is really an OWI system with separate administrative and conviction-side license rules. The immediate practical issues are the 10-day appeal deadline, the first-revocation split between 180 days for a failed test and 1 year for refusal, and the fact that lawful driving during revocation usually runs through a temporary restricted license with ignition interlock, SR-22, and fee compliance. Iowa also keeps a distinct under-21 zero-tolerance rule at 0.02 BAC and blocks reinstatement until the drinking drivers course and evaluation or treatment requirements are satisfied.
Kansas DUI Laws
Kansas DUI law runs on two linked tracks: the criminal DUI case under K.S.A. 8-1567 and the Division of Vehicles license action under K.S.A. 8-1014 and 8-1020. Adult DUI covers a 0.08 BAC, a 0.08 BAC measured within three hours, alcohol impairment, drug impairment, and combined alcohol-and-drug impairment. The most useful Kansas details are the 14-day hearing deadline, the much harsher license result for a test refusal, the first-occurrence escalation when BAC is 0.15 or greater, and the separate under-21 rule that starts at 0.02 BAC.
Kentucky DUI Laws
Kentucky DUI law is broader than a simple 0.08 driving rule. The statute covers operating or being in physical control of a vehicle at 0.08 or more within two hours, alcohol impairment, drug impairment, combined alcohol-and-drug impairment, certain controlled-substance detections, and a separate 0.02 rule for drivers under 21. The most useful Kentucky details are the 10-year lookback, the split between court penalties and Transportation Cabinet suspension rules, the fixed post-2020 suspension periods, and the way refusal can create both a separate suspension track and harsher repeat-offense jail exposure.
Louisiana DUI Laws
Louisiana's DUI system is split more sharply than many benchmark pages suggest. The arrest side runs through OMV's submit or refusal suspensions, while the conviction side runs through separate DWI or UDUI suspension periods and ignition-interlock rules. The practical Louisiana rules are that a qualifying arrest usually triggers license seizure and a temporary receipt that lasts up to 30 days, a first adult submit at 0.08 to 0.14 brings a 180-day OMV suspension, a first refusal on or after September 1, 2009 brings 365 days, and high-BAC first or second alcohol cases move into longer suspension-and-interlock lanes. Drivers under 21 also face a separate 0.02 underage standard.
Maine DUI Laws
Maine calls drunk-driving offenses OUI, and the license consequences can start before the criminal case ends. The practical rules are 0.08 BAC for standard adult OUI, a 10-day deadline to request a hearing on an administrative suspension, a 150-day first-offense suspension that may be reduced to 30 days served with ignition interlock, and a 0.00 alcohol condition for drivers under 21 on provisional licenses. Refusing the chemical test usually brings longer administrative suspensions and higher minimum criminal penalties than a straightforward first OUI.
Maryland DUI Laws
Maryland does not treat impaired driving as one flat 0.08-BAC offense. The state separates Driving Under the Influence of Alcohol (DUI) from Driving While Impaired by Alcohol (DWI), then layers a separate administrative-per-se system on top when a driver either tests 0.08 or higher or refuses the chemical test. Official Maryland sources also make clear that the 0.15-and-higher and refusal cases are treated more harshly for restricted-license purposes, that drivers under 21 carry an any-alcohol restriction, and that ignition-interlock participation can be required not only after convictions but also after probation before judgment for DUI or DWI.
Massachusetts DUI Laws
Massachusetts calls drunk driving OUI, and the state handles it on two tracks at once: immediate RMV action after a failed or refused chemical test, and the separate court case. The practical thresholds are 0.08 for most drivers, 0.02 for drivers under 21, and 0.04 while operating a commercial motor vehicle. For drivers 21 or older, a breath-test failure at 0.08 or above brings an immediate 30-day RMV suspension unless the case is resolved through first-offender 24D, while a chemical-test refusal triggers 180 days with no prior OUI history, 3 years for an under-21 driver or a driver with one prior, 5 years with two priors, and lifetime with three or more. On the court side, the RMV's over-21 materials list found-guilty suspension periods of 1 year, 2 years, 8 years, 10 years, and lifetime by offense count, but some first offenders may instead receive a 24D disposition with a 45- to 90-day suspension and alcohol education; second and subsequent OUI-related reinstatements generally require an ignition interlock device.
Michigan DUI Laws
Michigan's official sources do not treat every DUI search as one offense chart. The state primarily uses OWI and OWVI terminology, layers in a separate high-BAC rule at 0.17 or higher, uses zero-tolerance rules for drivers under 21, and applies a 0.04 threshold in commercial vehicles. The practical Michigan details are the 14-day implied-consent hearing deadline after a chemical-test refusal, the restricted-license-with-interlock option after 45 days for a first high-BAC conviction, and the fact that repeat alcohol cases often turn into Secretary of State hearing and restoration problems rather than simple ticket matters.
Minnesota DUI Laws
Minnesota's official law uses DWI rather than DUI, and the state splits the problem between criminal degree rules in chapter 169A and separate license-revocation and ignition-interlock rules in chapter 171. A Minnesota DWI can be based on impairment, being in physical control, a 0.08 alcohol concentration within two hours, a 0.04 CDL result, certain controlled-substance detections, cannabis impairment, or test refusal. The most useful Minnesota-specific details are the aggravating-factor system, the difference between the 10-year criminal lookback and the 20-year license lookback, and the way repeat cases shift quickly from fixed revocation periods into ignition interlock and treatment requirements.
Mississippi DUI Laws
Mississippi's official DUI materials work best when you treat one stop as several possible license problems instead of one generic first-offense chart. The state uses the regular adult DUI rule for impairment or 0.08 BAC, a separate under-21 zero-tolerance lane at 0.02 up to under 0.08, and a 0.04 BAC threshold for CDL operation. On the license side, DPS says the arrest receipt is only a 30-day temporary permit, refusal usually brings a 90-day Class R suspension, a first conviction brings a 120-day suspension unless the court orders ignition interlock instead, and repeat convictions escalate quickly into one-year and felony lanes. Mississippi also makes clear that ordinary hardship licenses are not the DUI path here.
Missouri DUI Laws
Missouri's official DWI system runs on two tracks at once. The criminal case can produce points, a 90-day first-offense suspension, a 1-year revocation after a prior alcohol conviction, a 5-year denial for a second alcohol- or drug-related offense within 5 years, and a 10-year denial after three or more intoxication-related traffic offenses. Separate from that, Missouri's administrative alcohol law can suspend or revoke the driving privilege whenever the BAC test is over the legal limit or the driver refuses testing. The practical Missouri details worth keeping near the top are the 15-day deadline to request an administrative hearing, the .020 under-21 administrative trigger, and the fact that first alcohol convictions may convert into a 30-day suspension plus 60-day Restricted Driving Privilege or an immediate 90-day IID-based restricted privilege.
Montana DUI Laws
Montana's DUI rules split quickly between criminal penalties and driver-license sanctions. The practical numbers are 0.08 for most adult alcohol cases, 0.02 for drivers under 21, and 0.04 for commercial drivers operating a commercial vehicle. On the license side, Montana MVD currently lists a 6-month suspension for a first DUI or 0.08-plus conviction, 6 months for a first refusal, and 90 days for a first under-21 0.02-plus conviction. On the criminal side, first-offense penalties can reach six months in jail and a $600 to $1,000 fine, and a fourth or subsequent DUI is a felony.
Nebraska DUI Laws
Nebraska DUI law is not just an adult .08 rule. Official state sources split the issue into the criminal DUI offense, the implied-consent refusal offense, and the DMV's Administrative License Revocation process after arrest. The practical Nebraska details are the lower .02 under-21 and .04 commercial thresholds, the 15-day temporary license and 10-day ALR hearing deadline, the fact that a first failed-test ALR is 180 days while a refusal ALR is 1 year, and the large role of ignition interlock. Nebraska's statutes and DMV materials also make clear that repeat convictions look back 15 years and can move quickly into long revocations and felony territory.
Nevada DUI Laws
Nevada DUI cases split into two tracks from the start: DMV administrative action and criminal court penalties. The official Nevada materials use a .08 BAC standard for most drivers, .02 for drivers under 21, and .04 in commercial driving, while also allowing arrest and conviction at lower BAC levels or for controlled substances. The practical Nevada details are the immediate 185-day administrative revocation for illegal-per-se test results, the at-least-1-year revocation for refusing an officer-directed test, the seven-year lookback for repeat offenses, and the state's unusual rule that a DUI revocation can often be reinstated early with ignition interlock but that doing so ends the chance to request a DMV hearing on the revocation.
New Hampshire DUI Laws
New Hampshire uses DWI rather than DUI, and the law splits into two tracks: administrative license suspension after a failed test or refusal, and the separate court-ordered revocation after conviction. The core thresholds are 0.08 for most drivers, 0.02 for drivers under 21, and 0.04 in a commercial motor vehicle. On the administrative side, a failed test brings a 6-month suspension on a clean record or 2 years with a prior refusal, DWI, aggravated DWI, or prior administrative suspension, while a refusal brings 180 days on a first incident with no prior DWI history or 2 years with a prior refusal or DWI. On the court side, a first DWI conviction means at least 9 months of revocation, aggravated DWI usually means at least 18 months plus ignition interlock, a second offense within 10 years means at least 3 years, and a third or later offense leads to indefinite revocation with a multi-year wait before reapplication.
New Jersey DUI Laws
New Jersey's DUI system is less about an immediate DMV hearing and more about court-imposed penalties that the MVC then enforces through suspension, interlock, and restoration rules. The core state splits are the 0.08 adult BAC threshold, the separate under-21 standard at 0.01 BAC, and the much harsher first-offense lane once the BAC reaches 0.10 or the case involves drugs. New Jersey also makes 0.15 especially important because that first-offense level requires ignition interlock during the suspension and for months after restoration. Refusal to take the breath test carries its own escalating suspension ladder, and DUI-related surcharges can keep the case expensive long after the court date ends.
New Mexico DUI Laws
A useful New Mexico DUI page should start with the two-track structure. The Motor Vehicle Division says a DWI case can trigger both a criminal court action under section 66-8-102 and a separate administrative revocation under the Implied Consent Act, and those proceedings are independent. The current MVD pages also make New Mexico-specific thresholds and license consequences unusually clear: 0.08 for most drivers 21 and older, 0.04 for CDL holders, and 0.02 for drivers under 21 in the implied-consent setting; a ten-day hearing-request deadline; one-year criminal revocation even on a first conviction; and ignition interlock that applies even to first-time DWI offenders.
New York DUI Laws
New York's alcohol- and drug-driving laws are more layered than a generic DUI page suggests. The state primarily uses DWI, Aggravated DWI, and several DWAI categories instead of one universal DUI label, and it also runs a separate Zero Tolerance system for drivers under 21. The practical New York details are the line between DWAI/Alcohol and DWI, the fact that a chemical-test refusal creates its own DMV hearing and revocation track, the mandatory ignition-interlock requirement for DWI convictions sentenced on or after August 15, 2010, and the way repeat alcohol or drug cases can turn into long revocations or even permanent revocation review by DMV.
North Carolina DUI Laws
North Carolina uses DWI rather than DUI, and the state splits the problem between immediate license action and later conviction consequences. The core offense standard is appreciable impairment or an alcohol concentration of 0.08 or more, with 0.04 or more in a commercial motor vehicle. On the front end, the implied-consent process can trigger an immediate civil revocation for at least 30 days, and a willful refusal can also bring a separate 12-month DMV revocation unless the driver requests a hearing before the order takes effect. On the back end, NCDMV says a first DWI conviction revokes the license for 1 year, a second for 4 years, and a third or subsequent offense permanently, while North Carolina sentencing itself uses six punishment levels rather than a single flat first-offense chart. Restoration also stays tied to a substance-abuse assessment and, in many higher-risk cases, an ignition interlock restriction.
North Dakota DUI Laws
North Dakota DUI law is broader than a simple 0.08 driving rule. The Century Code makes it illegal to drive or be in actual physical control while over the legal limit, under the influence, under impairing drugs, under combined alcohol and drug impairment, or after refusing a required chemical test. The practical North Dakota details are the split between criminal penalties and separate implied-consent license actions, the 10-day deadline to request an administrative hearing after the temporary permit is issued, the way BAC 0.16 and 0.18 change consequences, and the fact that repeat alcohol cases tie into the 24/7 Sobriety Program and temporary restricted-license rules.
Ohio DUI Laws
Ohio's official sources use OVI, not generic DUI, and they split the problem into arrest-side license action and conviction-side penalties. The practical Ohio rules are the 0.08 adult alcohol threshold, the separate under-21 OVUAC range from 0.02 up to under 0.08, and the fact that an administrative license suspension can start immediately after a failed test or refusal. Ohio's current BMV guidance says a positive-test ALS runs from 90 days up to five years, a refusal ALS runs from one to five years, and first-offense court penalties typically start with a mandatory three days plus a one- to three-year suspension.
Oklahoma DUI Laws
Oklahoma DUI law is broader than a simple 0.08 driving rule. The state treats driving, operating, or being in actual physical control of a vehicle as DUI when the person is at 0.08 or more, under the influence of alcohol, under the influence of another intoxicating substance, under the combined influence of alcohol and another intoxicating substance, or has a qualifying Schedule I substance or metabolite in the body. Drivers under 21 are handled under a stricter any-measurable-alcohol rule, and 0.15 or more creates aggravated DUI. The practical Oklahoma split is between the implied-consent revocation that can follow a failed or refused test even without a conviction, and the post-arrest interlock and restoration system that now runs through IDAP for DUI arrests on or after November 1, 2022.
Oregon DUI Laws
Oregon treats DUII as more than one problem. Official state sources separate the criminal DUII case, the DMV's implied-consent suspension, and in some cases the court-run diversion path. The practical Oregon details are the 0.08 adult alcohol threshold, the under-21 any-alcohol implied-consent rule, the 30-day temporary permit after arrest, the 10-day hearing deadline for many implied-consent cases, and the fact that conviction-based suspensions and implied-consent suspensions can run separately. Oregon also gives diversion unusual practical weight because eligible defendants can seek a one-year diversion agreement, while conviction-driven ignition interlock requirements then scale to one, two, or five years depending on the case.
Pennsylvania DUI Laws
Pennsylvania does not treat every DUI the same. The state uses general impairment, high-rate, and highest-rate categories, pushes under-21, commercial, and school-bus cases into stricter tracks at lower BAC levels, and treats a chemical-test refusal as its own PennDOT suspension problem. The practical Pennsylvania wrinkle many summaries miss is that a first general-impairment conviction for a legal-drinking-age driver carries no PennDOT license action, while higher tiers, refusal cases, and later offenses do.
Rhode Island DUI Laws
Rhode Island's DUI system is more segmented than many benchmark pages suggest. The basic DUI threshold is 0.08, but first-offense sentencing changes again at 0.10 and 0.15, refusal to take the chemical test is a separate charge with its own suspension ladder, and repeat penalties now run on a 10-year lookback for both DUI and refusal. Rhode Island also has a distinct under-21 impaired-driving rule at 0.02 for drivers age 18 to 20, separate family-court tracks for drivers under 18, and an interlock-hardship structure that can reduce part of a suspension if the court approves conditional driving.
South Carolina DUI Laws
South Carolina DUI law is really a mix of separate criminal and DMV tracks. The state still distinguishes DUI, which turns on appreciable impairment, from DUAC, which turns on an alcohol concentration of 0.08 or more, but both offenses use the same escalating penalty ladder and the same 10-year prior-offense lookback. The practical timing rules are what many summaries miss: refusal or a test result of 0.15 or more can trigger an immediate DMV suspension with a 30-day contested-case-hearing deadline, drivers under 21 face a separate 0.02 zero-tolerance suspension system, and current South Carolina law now routes all DUI and DUAC convictions tied to violations dated on or after May 19, 2024 into ignition interlock if the person wants to drive again.
South Dakota DUI Laws
South Dakota DUI law is broader than a simple 0.08 driving rule. The statute covers driving or being in actual physical control with a 0.08 BAC or while impaired by alcohol, marijuana, controlled substances, prescribed drugs that make safe driving impossible, or certain other substances. The practical South Dakota details are the separate refusal-based revocation track, the 120-day deadline to request a refusal hearing, the 120-day temporary license tied to the notice of intent to revoke, the 0.17 BAC triggers for first-offense evaluation and some permit conditions, and the state's 10-year lookback for most repeat-offense counting.
Tennessee DUI Laws
Tennessee's DUI system is not just one penalty box. The state separates DUI conviction penalties, implied-consent refusal revocations, the underage driving-while-impaired offense, and the interlock and restricted-license rules. The practical Tennessee details are the one-to-eight-year revocation ladder, the separate license revocation for refusing chemical testing, and the fact that DUI convictions tied to violations after July 1, 2016 generally require ignition interlock for at least 365 days when the driving privilege is reinstated.
Texas DUI Laws
A strong Texas DUI page should explain that adult Texas cases are mainly DWI cases and that one arrest can create two separate license tracks: the civil Administrative License Revocation process and the criminal conviction consequences. The most useful Texas details are the 15-day ALR hearing deadline, the 90-day versus 180-day first-offense adult ALR split for failed tests and refusals, the fact that ALR can stack on top of a conviction suspension from the same arrest, and the conviction-side requirements for alcohol education, SR-22 coverage, reinstatement fees, and sometimes interlock-restricted or occupational driving.
U.S. Virgin Islands DUI Laws
The current U.S. Virgin Islands DUI picture is best read through two official layers. The VIPD's public impaired-driving guidance still states the core adult rules: it is illegal to drive with a 0.08 BAC or higher, to drive under the influence of intoxicating liquor or Schedule I-V controlled substances, or to drive under their combined influence, and drivers can still be treated as impaired below 0.08. The Legislature then amended Title 20, section 493 through Bill No. 36-0123, later referenced in a 2026 bill as Act No. 9054, to add a 0.04 BAC rule for commercial motor vehicles and a detectable-alcohol rule for drivers under 21. The bill text available on the Legislature site also pairs the under-21 offense with a 12-month suspension and creates a separate commercial-vehicle penalty ladder that starts at $3,000 to $5,000 for a first offense and rises sharply for repeat offenses. Superior Court Rule 160 matters too because DUI is not a violations-clerk payable offense, so these cases belong on a court track instead of a routine ticket-payment path.
Utah DUI Laws
Utah DUI law is more Utah-specific than most benchmark pages suggest. The state uses a 0.05 BAC standard for ordinary adult DUI cases, runs separate criminal and Driver License Division tracks after an arrest, and gives only 10 days to request a DLD hearing while allowing driving for up to 45 days from the arrest date before the administrative action takes effect. Official Utah sources also make the license consequences unusually important: a first per-se suspension for a driver 21 or older is 120 days, a first refusal is 18 months, and drivers under 21 face a separate any-measurable-alcohol "not a drop" suspension system.
Vermont DUI Laws
Vermont DUI law runs on two tracks at once: a civil suspension under 23 V.S.A. section 1205 and criminal penalties under section 1210. For most drivers, the alcohol limit is 0.08, but it is 0.04 in a commercial motor vehicle and 0.02 in a school bus. A refusal to submit to an evidentiary test brings a six-month civil suspension, while a test at or above the legal limit brings 90 days, and both also require compliance with Vermont's reinstatement rules under section 1209a. The most Vermont-specific wrinkle is the repeat-offender high-BAC rule: after a second or subsequent DUI proven at 0.16 or more, the driver faces a three-year 0.02 restriction, and a later civil suspension for violating that 0.02 rule is for life.
Virginia DUI Laws
Virginia's DUI system is best understood as several connected tracks rather than one penalty box. The Commonwealth separately handles the DUI offense itself, under-21 illegal-consumption cases, unreasonable refusal of chemical testing, the immediate administrative suspension after arrest, and the ignition-interlock and VASAP requirements tied to restricted driving and restoration. The practical Virginia details are the seven-day or longer administrative suspension at the front end, the one-year to indefinite revocation ladder after conviction, and the strong role ignition interlock now plays even for many first-offense cases.
Washington DUI Laws
Washington DUI law works on two separate tracks from the same arrest. The Department of Licensing handles the administrative license action, while the court handles the criminal case, and they run independently. Official Washington sources also make the practical details unusually important: adults are at 0.08 BAC, CDL cases use 0.04, drivers under 21 hit trouble at 0.02, a DUI hearing request must be made within 7 days, the temporary license is usually good for 30 days, and the arrest-based suspension can start before the court case ends.
West Virginia DUI Laws
West Virginia's DUI system is more court-driven than many older state summaries suggest. Since July 1, 2020, the old administrative hearing process no longer governs new DUI license cases, and refusal review now runs through the court process. The practical numbers are 0.08 for ordinary alcohol DUI, 0.15 for the aggravated first-offense alcohol tier, and 0.02 to below 0.08 for the under-21 alcohol offense. West Virginia also makes the Motor Vehicle Alcohol and Drug Test and Lock Program central: a first under-0.15 DUI can shift to 15 days of revocation plus 125 days of ignition interlock, while a first refusal can shift to 45 days of revocation plus one year in the program.
Wisconsin DUI Laws
Wisconsin officially calls impaired driving OWI, and a good Wisconsin DUI page has to separate three different lanes that generic summaries blur together: the OWI or PAC case itself, the six-month administrative suspension that follows a prohibited-alcohol-concentration test result, and the separate refusal revocation process under implied consent. The current practical rules are specific. Most drivers use a 0.08 PAC threshold, commercial drivers use 0.04, first-offense OWI is usually a forfeiture with a 6-to-9-month revocation rather than jail, and repeat cases escalate quickly into mandatory confinement, longer revocations, IID requirements, and eventually felony exposure and possible lifetime revocation.
Wyoming DUI Laws
Wyoming's DUI system splits between the criminal case, the immediate administrative action, and the later license-restoration rules. The core offense reaches both driving and actual physical control, covers a standard 0.08 threshold plus impairment by alcohol or drugs, and uses a separate underage drinking-and-driving rule at 0.02. The most useful Wyoming details are the 90-day administrative suspension after a failed test, the six-month or eighteen-month refusal suspension under implied consent, and the way ignition interlock becomes mandatory for a first alcohol DUI at 0.15 or above and for second or later DUI convictions regardless of BAC.
