For a first DUI, how long your license is suspended usually falls between 90 days and one year, with the exact length turning on your state, your BAC at arrest, and whether anyone was hurt. Repeat convictions stretch that into years, and refusing the breath or blood test often triggers a longer suspension than the DUI charge itself. One quirk surprises almost everyone: a single arrest can produce two separate suspensions, one from the DMV and one from the criminal court.
Two Suspensions From One Arrest
Most states impose two separate license suspensions after a DUI arrest, and each runs on its own timeline with its own rules.
The Administrative Suspension
The first suspension comes from your state’s motor vehicle agency, not a court. When you’re arrested, the agency receives a report that you either tested at or above 0.08% BAC or refused testing, and it suspends your license on that basis alone, usually within about 30 days of the arrest. This “administrative per se” suspension happens whether or not a prosecutor ever files charges.
You have a narrow window to challenge it, often just 7 to 15 days after the arrest depending on the state. Miss the deadline and the suspension takes effect automatically. At the hearing, the agency only has to show that the stop and arrest were lawful and that you tested over the limit or refused, using a “more likely than not” standard rather than the criminal court’s “beyond a reasonable doubt.”
The Criminal Suspension
The second suspension comes from a judge as part of your sentence if you’re convicted or plead guilty. Because criminal cases move on their own schedule, this one may not begin until months after the arrest. Its length depends on your state’s sentencing laws and the facts of your case.
Most states let these two suspensions overlap, or credit time already served on the administrative suspension toward the criminal one, so you generally won’t serve both back-to-back. In some states, an acquittal in criminal court can even void the administrative suspension, though that’s the exception.
First-Offense Suspension Lengths
For a first DUI with no aggravating factors, the range across the country is 90 days to one year. Where you fall depends on the details. A BAC well above 0.08% often triggers a longer suspension on its own. Causing an accident, having a minor in the vehicle, or driving well over the speed limit can push you toward the upper end.
Some states set a flat mandatory minimum, such as six months, that applies regardless of circumstances. Others give judges discretion to shorten the suspension if you enroll in a DUI education program or complete community service. The trend over the past decade has been toward stricter mandatory minimums with less judicial discretion to reduce them.
Many states also offer a hardship or restricted license partway through the suspension, letting you drive to work, school, treatment, or medical appointments. These aren’t automatic. You typically have to apply, prove genuine need, serve a portion of the hard suspension first, and install an ignition interlock in any vehicle you drive.1National Conference of State Legislatures. State Ignition Interlock Laws A hardship license shortens the time you’re fully off the road; it doesn’t shorten the underlying suspension.
Repeat Offenses
Penalties climb steeply with each additional DUI. A second conviction typically brings a one-to-two-year suspension. A third or fourth can mean revocations of five years, ten years, or a permanent loss of driving privileges, and most states elevate a third or fourth DUI to a felony with prison time on top.
Whether a prior DUI counts depends on your state’s “lookback period.” Some states look back only five years, so a DUI from six years ago wouldn’t trigger enhanced penalties. Others use ten-year windows, and a handful treat every prior DUI as relevant no matter how old. If your prior falls outside the lookback period, the state sentences you as a first-time offender, though the old conviction still shows on your driving record.
Refusing the Chemical Test
Every state has an implied consent law: by driving on public roads, you’ve already agreed to submit to a breath, blood, or urine test if an officer has probable cause to suspect impairment. Refusing triggers its own license suspension, entirely separate from any DUI penalty.
First-time refusal suspensions generally run 90 days to one year, with several states imposing a full year. A second refusal pushes the suspension to one to three years in most states. This suspension applies even if you’re never convicted of DUI and even if the charges are dropped, because the refusal itself is the violation. Prosecutors can also use your refusal against you at trial, arguing you declined the test because you knew the results would be incriminating.
If You Hold a Commercial Driver’s License
A DUI hits CDL holders harder, and it hits them even when the arrest was in a personal vehicle. Federal law sets the BAC threshold for commercial operators at 0.04%, half the standard limit.2Federal Motor Carrier Safety Administration. Is a Driver Disqualified for Driving a CMV While Off-Duty With a Blood Alcohol Concentration Over 0.04 Percent
A first DUI conviction disqualifies you from operating any commercial vehicle for at least one year. A second conviction results in a lifetime disqualification, though federal regulations allow reinstatement after a minimum of ten years under certain conditions.3Office of the Law Revision Counsel. 49 USC 31310 – Disqualifications Even a single DUI can effectively end a commercial driving career, since many trucking companies won’t hire drivers with a DUI on their record regardless of legal eligibility.
A DUI Follows You Across State Lines
Moving to another state or getting arrested away from home won’t help you dodge a suspension. Two federal systems close that gap.
The Driver License Compact, joined by 47 states, operates on the principle of “one driver, one license, one record.” A DUI conviction in a state other than where you’re licensed is reported to your home state, which then applies its own penalties as if the offense happened locally.4The Council of State Governments. Driver License Compact
The National Driver Register, a federal database, flags anyone whose license has been revoked, suspended, or canceled. When you apply for a license in any state, that state checks the register and sees your suspension history.5National Highway Traffic Safety Administration.

Reinstatement Isn’t Automatic
The end date of your suspension isn’t the day you can legally drive again. Reinstatement requires that you complete every court and DMV requirement and then take steps to restore your license.
- Finish any court-ordered DUI education, alcohol treatment, or substance abuse evaluation. The evaluation alone typically runs $100 to $350.
- Pay all outstanding court fines plus a reinstatement fee to the motor vehicle agency.
- File an SR-22 certificate through your insurer as proof of at least state-minimum coverage. Most states require SR-22 filings for about three years, though some require as little as one year and others up to five. If your coverage lapses, the insurer notifies the state and your license can be re-suspended, with the SR-22 clock potentially resetting.
- Install an ignition interlock if your state or your sentence requires it. Thirty-one states and the District of Columbia require interlock installation for all DUI offenders, including first-timers, while the rest generally mandate them for a second offense or a high BAC. Expect roughly $70 to $100 per month in lease and calibration fees, plus installation.7Centers for Disease Control and Prevention. Increasing Alcohol Ignition Interlock Use
- Retake part or all of the driving exam if your state requires it.
Skip any step and your reinstatement application gets denied. People who assume their license comes back automatically at the end of the suspension period sometimes drive for months without realizing they’re still legally suspended.
