How long do I have to request a Delaware DUI administrative hearing?

Delaware DMV says you have 15 days from the arrest to request the administrative hearing. If no hearing is requested, the license is revoked when the 15-day temporary license ends.

What happens if I refuse the chemical test in Delaware?

The Delaware DMV FAQ says an unfavorable administrative ruling for refusal causes a 12-month revocation for a first refusal, 18 months for a second refusal, and 2 years for a third refusal. Refusal also increases conviction-side revocation periods under section 4177A.

Is ignition interlock optional in Delaware DUI cases?

Not in the broad sense many drivers expect. Delaware's current DMV ignition page says the state has both a First Offense Election-IID diversion path and a voluntary IID path for certain refused-test or repeat-alcohol cases, and the statute also makes IID part of post-conviction reinstatement structure.

Do I have to complete alcohol education or treatment before Delaware will reinstate my license?

Yes. Delaware DMV says no driver's license will be reinstated for a DUI offense until the driver satisfactorily completes the required course of instruction or program of rehabilitation identified through screening.

Delaware DUI laws: 15-day administrative deadlines, first-offender election limits, and mandatory IID structure

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.

Overview

What this page helps you verify

Delaware DUI content should not be written as one flat penalty chart. Current official Delaware sources separate the arrest-side administrative hearing and revocation process, the court conviction or diversion outcome, the mandatory alcohol evaluation and education or treatment process, and the IID licensing rules. The best version of this page should help a reader answer four practical questions fast: whether a DMV hearing deadline is still open, whether the case may qualify for the First Offender Election, how BAC or refusal changes the revocation period, and when IID becomes the only realistic way to drive before full reinstatement.

Typical flow

What the process often looks like

Treat the DMV administrative case and the criminal court case as separate tracks immediately, because Delaware imposes both administrative and criminal consequences.
If you want to challenge the administrative revocation, request the hearing within 15 days of arrest instead of assuming the court date preserves that right.
Check quickly whether the case may qualify for the First Offender Election, because that option has specific moving-violation, injury, BAC, license-status, and child-passenger limits.
If you cannot avoid a revocation period, shift early to the education or treatment screening process and the IID eligibility rules, because Delaware ties reinstatement and limited driving privileges to those requirements.

Two tracks

A Delaware DUI arrest can trigger a DMV revocation case and a criminal case at the same time

This is the first structural point the page should make.

Delaware DMV says a person who drives under the influence of alcohol or drugs is subject to both criminal and administrative penalties.
The DUI statute separately defines the criminal offense, while the DMV FAQ explains that the arresting officer generally takes the license and issues a 15-day temporary license.
If no administrative hearing is requested within that 15-day period, the Delaware FAQ says the revocation begins when the temporary license expires.

What counts as DUI

Delaware's DUI statute is broader than a simple .08 rule

The state uses impairment, alcohol-concentration, and drug-content theories in the same statute.

Delaware Code section 4177 covers driving under the influence of alcohol, any drug, or a combination of alcohol and a drug.
The same statute also makes it DUI when a person's alcohol concentration is .08 or more, or is .08 or more within 4 hours after driving if that alcohol was present while the person was driving.
Delaware separately allows prosecution when a person's blood contains, within 4 hours of driving, any amount of an illicit or recreational drug resulting from unlawful use or consumption.
The statute defines 'while under the influence' as being less able than the person would ordinarily have been to exercise clear judgment, sufficient physical control, or due care.

Administrative revocation

The first Delaware deadline is the administrative hearing request, and refusal makes the license problem worse

This is usually the most urgent practical issue after arrest.

The Delaware FAQ says the administrative hearing examines probable cause, whether the evidence shows DUI, and whether the driver refused a chemical test after being informed of the refusal penalty.
If the hearing result is unfavorable, the FAQ lists probable-cause revocations at 3 months for a first offense, 12 months for a second offense, and 18 months for a third offense or more.
The same FAQ lists chemical-test-refusal revocations at 12 months for a first refusal, 18 months for a second refusal, and 2 years for a third refusal.
Delaware's DUI statute also says that a guilty plea to section 4177 waives the right to the administrative hearing and withdraws any earlier request.

Court-side penalties

Delaware conviction penalties and revocation periods escalate by prior history and by BAC tier

This is where statewide guidance should stay precise and statute-based.

For a first DUI conviction, section 4177 says the person is fined $500 to $1,500 or imprisoned for up to 12 months, or both.
For a second offense within 10 years, the statute sets a $750 to $2,500 fine and 60 days to 18 months of imprisonment, with the minimum sentence not suspendable.
Section 4177A separately sets conviction-side revocation periods at 12 months for a first offense, 18 months for a second, 24 months for a third, and 60 months for a fourth or later offense.
Those conviction revocation periods increase when BAC is .15 or more, and they increase further when BAC is .20 or more or the person refused a chemical test.

First Offender Election and IID

Delaware's first-offender diversion and IID rules are more specific than a generic hardship-license model

This is where the state-specific operational rules matter most.

Section 4177B says the First Offender Election is available only if the person has no prior DUI-type offense, has fewer than 3 moving violations within 2 years, was not in an injury crash, was not at an alleged BAC of .15 or more, was not unlicensed or suspended, and is not in the child-passenger enhancement category.
The statute and the DMV ignition page both say the first-offender election waives the administrative hearing, and the election triggers a 1-year revocation unless the person moves into the IID path.
Delaware's ignition page says a first-offender election participant may seek the FOE-IID diversion after at least one month has elapsed since the revoked license was received by DMV, and must remain on the IID license for 5 months.
For post-conviction IID licenses, the current ignition page says a first offender generally waits at least 30 days if BAC was below .15, while section 4177C uses longer waits for repeat offenders and longer IID participation periods based on offense number and BAC.

Evaluation and special classes

Delaware ties reinstatement to screening and treatment, and it also keeps separate under-21 and CDL alcohol rules

These rules are important enough to surface on the main page.

Delaware DMV says no license will be reinstated for a DUI offense until the driver satisfactorily completes the course of instruction or program of rehabilitation determined by a screening evaluation.
The DMV's current Driver Improvement page says screenings are free and can result in 16 hours of DUI education, 16 hours of DUI treatment, or 27 hours of extended treatment.
Delaware's under-21 alcohol-driving law revokes a minor's license for 2 months on a first offense and 6 to 12 months on later offenses, and .02 or more is per se evidence that the underage driver had consumed alcohol.
For commercial drivers, Delaware separately prohibits operating a commercial motor vehicle at .04 or more BAC or while impaired by drugs.

Accuracy notes

Where people get tripped up

Delaware DUI content should separate administrative revocation from criminal conviction consequences. The official materials treat them as independent tracks, and the first deadline is the 15-day DMV hearing window.
Do not flatten Delaware into a simple '.08 only' DUI state. Section 4177 also covers impairment, certain within-4-hours alcohol cases, and unlawful-use illicit or recreational drug content in blood within 4 hours of driving.
The First Offender Election is narrower than many benchmark summaries imply. BAC of .15 or more, three or more moving violations within two years, injury to another person, driving while unlicensed or suspended, or the child-passenger enhancement all block that route.
IID should not be described as a generic hardship license. Delaware now uses specific IID diversion and reinstatement paths with waiting periods, Delaware vehicle requirements, enrollment or completion requirements, and extension penalties for violations.
Under-21 and CDL alcohol rules are separate from the standard adult .08 framework and should not be buried in fine print.
