Implied Consent: What Happens if You Refuse a Test

Implied consent is the rule that, by driving on a state’s roads, you have already agreed to a breath, blood or urine test if an officer lawfully arrests you for DUI. You can still say no in most situations. But states attach a price to refusing, and that price is usually a license suspension that starts fast and lasts longer than the one you would get for failing the test.

If you refused a test recently, the most urgent fact is the deadline to challenge the suspension. In Texas you have 15 days from the notice to request a hearing, and in Wisconsin you have 10 days to ask the court for one. Find yours with the DUI deadline calculator.

What Implied Consent Means When You Drive

Every state has an implied consent law. The idea is old: in exchange for the privilege of a license, you agree in advance to testing after a DUI arrest. The Supreme Court described the history in Birchfield v. North Dakota (2016). Originally, the only penalty for refusing was losing your license. Over time, states added more, and some, including North Dakota and Minnesota, made refusing a crime.

Three things are true almost everywhere:

• The test comes after an arrest. Implied consent covers the evidential test an officer asks for after arresting you, not a casual question at the roadside.
• Refusing triggers its own license action. It runs on its own track, separate from the criminal DUI case. In California, the DMV’s action is “independent of any court-imposed” penalty.
• The suspension can be challenged, but only on time. Each state sets a short window to request a hearing or file a petition.

What differs is how long the suspension lasts, whether refusing is a crime, whether a jury can hear about it, and whether refusing raises your sentence if you are convicted of DUI. That is the rest of this page.

Breath Tests, Blood Tests and Your Rights

The type of test matters. In Birchfield, the Supreme Court held that the Fourth Amendment allows a warrantless breath test after a lawful DUI arrest, but not a warrantless blood test. A blood draw is more intrusive, so police generally need a warrant, or an emergency that justifies skipping one. The Court also held that a state may not make it a crime to refuse a blood test based on implied consent alone. It left in place the civil penalties, such as license suspension, and the “evidentiary consequences” of refusing.

You can see this ruling in how states write their laws today:

• Minnesota makes refusing a breath test a crime, and refusing a blood or urine test a crime only when the officer has a search warrant (Minn. Stat. § 169A.20 subd. 2).
• Utah makes refusing a blood test after a judge issues a warrant a separate Class B misdemeanor (Utah Code § 41-6a-520.1).
• Wyoming gives no test after a refusal unless a search warrant is issued, including one sent remotely, or the crash caused serious injury or death (Wyo. Stat. § 31-6-102).
• West Virginia requires your written consent or a warrant for a blood test, and refusing a blood test alone can’t lead to revocation (W. Va. Code § 17C-5-4).

The small handheld test at the roadside is a different thing from the test after arrest. In Alaska, refusing that roadside preliminary breath test is an infraction, while refusing the chemical test after arrest is a crime (AS 28.35.031(e); AS 28.35.032).

How Long You Lose Your License for Refusing

A first refusal costs you your license for anywhere from 45 days (Connecticut, followed by interlock-only driving) to 2 years (Hawaii), depending on the state. In more than half of the 51 jurisdictions, the answer for a first refusal is about a year. Arizona is typical: 12 months, or 2 years for a second refusal within 84 months (A.R.S. § 28-1321).

The outliers on each end:

First refusal	State	What the statute sets
Shortest	Connecticut	45 days, then 1 year driving only with an ignition interlock (Conn. Gen. Stat. § 14-227b)
Short	Alabama	90 days with no prior contacts in 10 years (Ala. Code § 32-5A-304)
Short	Mississippi	90 days, or 1 year with a prior DUI (Miss. Code Ann. § 63-11-5)
Typical	Arizona, California, Colorado, Oregon	1 year
Long	Utah	18 months, then a two-year interlock restriction (Utah Code § 41-6a-521)
Longest	Hawaii	2 years with no prior contact in 10 years (Haw. Rev. Stat. § 291E-41)

Repeat refusals climb fast. Massachusetts suspends for 180 days with no priors, 5 years with two priors and for life with three or more (M.G.L. c. 90, § 24). Vermont’s ladder ends at life for a third refusal. Hawaii’s reaches 8 years with two or more priors.

The suspension for refusing is usually longer than the one for failing the test. That gap is the point of the law:

State	First refusal	First failed test
California	1 year	4 months (age 21+, 0.08 or more)
Texas	180 days	90 days
Colorado	1 year	9 months
Oregon	1 year	90 days
Washington	1 year	90 days
Maryland	270 days	180 days (0.08 to under 0.15)

Several states also add a fee or civil penalty to the suspension. Idaho charges a $250 civil penalty. New York adds a $500 civil penalty ($750 for a repeat within 5 years). Pennsylvania’s restoration fee is $500, $1,000 or $2,000.

The table below lists every state’s refusal penalty and suspension, with the statute and the date it was checked.

Refusing while driving on a license revoked, suspended or cancelled for a prior DUI conviction is a Class A misdemeanor with a fine up to $1,000 and at least 5 consecutive days in jail that cannot be suspended. Officers must give a breath test, with or without consent, after a crash that injured or killed someone, when a child under 16 is in the vehicle, or when the driver has a prior DUI or vehicular assault or homicide conviction. A blood test needs consent, a search warrant or exigent circumstances.
DWI law in Texas	License suspended (or a license denied) for 180 days, or 2 years if your record shows an alcohol- or drug-related enforcement contact in the previous 10 years. The suspension starts on the 40th day after notice unless you request a hearing within 15 days.
DUI law in Utah	License revoked for 18 months (36 months with a prior offense within 10 years), followed by a two-year interlock restriction and a 5- or 10-year alcohol-restricted driver status.

DUI law in Virginia	A first unreasonable refusal of a breath or blood test is a civil offense with a 1-year license suspension. A breath-test refusal within 10 years of a prior DUI or refusal is a Class 1 misdemeanor with a 3-year revocation; a repeat blood-test refusal is civil with a 3-year revocation. These periods are added to the administrative suspension, and refusal can be used as evidence at trial
DUI law in Washington	Revocation for at least 1 year (2 years with a prior incident within seven years); the refusal may be used against you in a criminal trial; on conviction a refusal is sentenced like a 0.15 or higher BAC and brings a 2-, 3- or 4-year revocation depending on priors
DUI law in West Virginia	License revocation of at least 45 days and up to life after a court order finding that you refused the designated secondary breath test. A refusal becomes final 15 minutes after you refuse. Refusing a blood test only cannot result in revocation, and a blood test needs your written consent or a warrant
OWI law in Wisconsin	revocation by court order: 1 year for a first improper refusal (occupational license after 30 days), 2 years with one prior counted within 10 years, 3 years with two or more priors; periods doubled with a minor passenger under 16; ignition interlock order; assessment and driver safety plan. You have 10 days from the Notice of Intent to Revoke to request a court hearing; without a request, revocation starts 30 days after the notice.
DUI law in Wyoming	if you refuse, no test is given unless a search warrant is issued (including a remotely communicated warrant) or serious bodily injury or death resulted; under a warrant a test of the agency's choice may be given

When a DUI Refusal Charge Is a Crime of Its Own

In most states, refusing is a civil matter: you lose your license, but you aren’t charged with a separate crime for saying no. A group of states goes further and makes refusal its own criminal charge.

• Alaska: refusal is a class A misdemeanor with the same mandatory jail, fine and interlock as a DUI. For a first offense that means at least 72 hours, $1,500 and 6 months of interlock, served on top of any other sentence.
• Minnesota: refusing a breath test, or a warranted blood or urine test, is third-degree DWI, a gross misdemeanor.
• Nebraska: refusal is a separate crime punished like DUI, plus a 1-year administrative revocation (Neb. Rev. Stat. § 60-6,197).
• North Dakota: refusal is a crime under the DUI statute, punished like a DUI (N.D. Cent. Code § 39-08-01).
• Rhode Island: a first refusal is civil, but a second within 10 years is a misdemeanor with up to 6 months in jail and a $600 to $1,000 fine (R.I. Gen. Laws § 31-27-2.1).
• Vermont: refusing is a crime if you have a prior DUI conviction, or if the crash caused serious injury or death (23 V.S.A. § 1201).
• Louisiana: if you have refused twice before, or after a crash with a death or serious injury, you may not refuse; doing it anyway carries a fine of $300 to $1,000 and 10 days to 6 months in jail (La. R.S. 32:666).

Because of Birchfield, these criminal refusal laws reach breath tests, or blood tests under a warrant, rather than a blood draw demanded on implied consent alone.

Can a Refusal Be Used Against You in Court?

In many states, yes. The prosecutor can tell the judge or jury that you refused, and argue that you refused because you expected to fail. Colorado, Delaware, Missouri, Oregon, South Carolina, Vermont and Washington are among the states whose statutes allow it. In D.C., if you have a prior DUI or OWI conviction, a refusal creates a rebuttable presumption that you were under the influence (D.C. Code § 50-1905).

A few states draw the line differently:

• Massachusetts: the refusal cannot be used as evidence at the criminal trial.
• Kentucky: a breath-test refusal may be used as evidence, but a blood-test refusal may not (KRS 189A.105).
• South Dakota: for adults, a refusal may be admitted at a DUI trial, and officers may require a blood draw after a DUI arrest (S.D. Codified Laws § 32-23-10.1).

Refusing Can Raise Your Sentence if You Are Convicted

Even where refusal isn’t its own crime, it can make a DUI sentence heavier.

• Alabama: a DUI conviction with a refusal requires 1 year of ignition interlock (Ala. Code § 32-5A-191(t)(2)).
• California: refusal is a special sentencing factor in the criminal case (Cal. Veh. Code § 23578).
• Maryland: if you are convicted and the refusal is proven, the court can add up to 2 more months of jail and a $500 fine (Md. Code, Transp. § 21-902(g)).
• Washington: a refusal is sentenced like a test result of 0.15 or higher (RCW 46.61.5055).
• Pennsylvania: a DUI conviction after refusing a breath test carries the highest-tier penalties (75 Pa.C.S. § 3804(c)).
• Maine: a refusal raises the mandatory minimum jail and fine if you are convicted of OUI (29-A M.R.S. § 2411(5)).
• Iowa: a refusal bars a deferred judgment (Iowa Code § 321J.2).

To see what a conviction carries in your state, use the DUI penalty estimator or read the first DUI guide.

The Deadline to Challenge a Refusal Suspension

A refusal suspension usually starts on a set day unless you act first, and the window to act is short.

• Texas: the suspension starts on the 40th day after notice unless you request a hearing within 15 days (Tex. Transp. Code § 724.041). See Texas refusal rules.
• Arizona: the suspension takes effect 30 days after the order is served unless you request a hearing in time. See Arizona refusal rules.
• Wisconsin: you have 10 days from the Notice of Intent to Revoke to request a court hearing; without one, revocation starts 30 days after the notice. See Wisconsin refusal rules.
• Idaho: you may request a court hearing in writing within 7 calendar days.
• Illinois: the summary suspension for refusing starts on the 46th day after notice (625 ILCS 5/11-501.1).
• Maine: a timely hearing request pauses a high-alcohol suspension, but not a refusal suspension.

The DUI deadline calculator gives the last day for your state from the date on your notice. The full sequence after an arrest is in what happens after a DUI.

What to Do Next

1. Find the notice the officer gave you. It names the agency or court and starts your clock.
2. Run your state and date through the deadline calculator and request the hearing before it closes.
3. Read your state’s refusal page from the state list to see the exact suspension, fees and any interlock rule. You can compare states side by side on DUI laws by state.
4. Ask whether you can drive at all during the suspension. Many states limit hardship licenses after a refusal, and some offer ignition interlock as the path back.
5. Talk to a lawyer licensed in your state, the state bar’s lawyer referral service, or ask the court about a public defender at your first appearance. The guide to finding a DUI lawyer explains how to check a lawyer’s license.

If your arrest happened at a roadblock, the DUI checkpoints guide explains where they are legal and how the stop works. For how BAC limits are set, see the blood alcohol content guide.

Frequently Asked Questions

Can I Refuse the Small Roadside Breath Test?

That depends on the state. The roadside or preliminary breath test is separate from the evidential test after arrest. In Alaska, refusing a roadside preliminary breath test is an infraction, while refusing the chemical test after arrest is a class A misdemeanor (AS 28.35.031(e); AS 28.35.032). Check your state page for its rule.

Do I Have the Right to Talk to a Lawyer Before Deciding?

It varies by state. Idaho's statute says there is no right to consult an attorney before testing (Idaho Code § 18-8002). If you were tested or refused without speaking to a lawyer, a lawyer licensed in your state can tell you whether that matters in your case.

Is Refusing Better Than Failing the Test?

No one can answer that for every case, and this guide doesn't give case advice. What the statutes show is that the license loss for refusing is usually longer than for failing. In California, a first refusal brings a 1-year suspension, compared with 4 months for a first failed test at 0.08 or more (Cal. Veh. Code §§ 13353, 13558).

Does a Refusal Suspension Count Against a Commercial License?

Yes, in the states that say so. Illinois disqualifies CDL holders from commercial driving after a refusal (625 ILCS 5/11-501.1), and Michigan suspends all vehicle group designations for 1 year for a refusal in a commercial vehicle (MCL 257.625f). See the CDL guide for the federal rules.

Can I Get a Hardship License After Refusing?

Often not. Massachusetts allows no hardship license during a refusal suspension, Kentucky allows none after a refusal, and Montana allows no probationary license during a refusal suspension. Maryland allows a modified license only through 1 year in its Ignition Interlock System Program. The hardship license guide covers each state.

What if I Agreed to the Test Only Because I Was Told Refusing Was a Crime?

The Supreme Court considered that situation in Birchfield v. North Dakota (2016) and held that motorists may not be criminally punished for refusing a blood test based on implied consent. Whether that affects a particular case is a question for a lawyer licensed in your state.
