A DUI conviction brings fines, possible jail time, and a license suspension, and the exact numbers depend on your blood alcohol level, your record, and whether anyone was hurt. For a standard first offense, DUI charges carry fines in the hundreds up to about $2,000, jail exposure from zero up to a year in county jail, and a license suspension that starts before you ever see a judge. Each repeat offense pushes the fines higher, adds mandatory minimum jail time, and eventually turns the charge into a felony punishable by state prison.
What Puts You Over the Line
In 49 states and the District of Columbia, driving with a BAC of 0.08% or higher is a per se DUI, meaning prosecutors only have to prove the number, not that your driving looked impaired. Utah lowered its threshold to 0.05% in 2018 and remains the only state with a stricter standard.1NHTSA. Lower BAC Limits You can still be charged below the per se limit if an officer has evidence that alcohol or drugs affected your driving.
Drivers under 21 face zero-tolerance laws in every state, with the legal BAC set at 0.00%, 0.01%, or 0.02% depending on where you are. Commercial drivers are held to a federal 0.04% limit that applies even when they’re off duty in a personal vehicle.2Office of the Law Revision Counsel. 49 USC 31310 – Disqualifications
First-Offense Fines and Jail
A standard first-offense DUI is a misdemeanor in every state. Base fines typically run from a few hundred dollars to $2,000, but that number is misleading. Court assessments, surcharges, and processing fees routinely push the total well beyond the base, and some jurisdictions effectively double or triple the stated fine once all the add-ons post.
Jail is possible on a first offense, though many first-time offenders avoid it. Maximum sentences range from six months to a year in county jail depending on the state. Some states impose mandatory minimums of 24 to 48 hours. Others let judges substitute community service or work-release.
Probation is nearly universal, running three to five years, with conditions that can include random testing, no-alcohol restrictions, a victim impact panel, and regular check-ins. Courts also require a DUI education or substance abuse program, typically three to nine months for a first offense, with enrollment fees generally between $75 and $250 that you pay yourself.
Second-Offense Fines and Jail
A second DUI within the state’s look-back window stays a misdemeanor in most states but gets significantly more expensive and far more likely to put you in a cell. Fines climb substantially, and mandatory jail time enters the picture, commonly 30 to 90 days where a first offense might have carried none. Probation runs longer, DUI education stretches to 18 months or more, and an ignition interlock device typically becomes mandatory.
The look-back period controls whether a prior counts. Some states use five years, others use ten, and states like Texas and Illinois apply a lifetime look-back, so a DUI from decades back still triggers the enhancement.
Third Offense and the Jump to Felony Prison Time
A third or fourth DUI is where many states cross from misdemeanor to felony. Roughly half the states elevate the charge on the third conviction; others wait until the fourth. New York and Oklahoma are among the few that can charge a second offense as a felony under certain circumstances.
Once the charge is a felony, you’re facing state prison rather than county jail, with sentences that can reach several years. Mandatory minimum jail terms of 60 days or more are common even in states that keep a third offense as a misdemeanor. License revocations at this level often last several years or become permanent, and courts can order long-term treatment and extend ignition interlock to three years or longer.
Aggravators That Raise the Penalty
Specific circumstances can push fines and jail well past the standard range, and some can turn a first-offense misdemeanor into a felony:
- High BAC. More than two dozen states impose enhanced penalties when BAC hits 0.15% or higher, often including mandatory minimum jail time, longer suspensions, and automatic ignition interlock, even on a first offense.3National Conference of State Legislatures. Increased Penalties for High Blood Alcohol Content
- Child in the vehicle. A minor passenger can add a separate child endangerment charge on top of the DUI, effectively doubling the penalties.
- Serious injury. A DUI that causes serious bodily injury is typically charged as a felony.
- A death. The charge becomes vehicular manslaughter or a similar offense, carrying prison sentences from a few years up to 15 or more depending on the state. Some states allow second-degree murder charges where the circumstances show extreme recklessness.
- Excessive speed. Driving significantly over the limit while impaired can add mandatory jail time and may be treated as a separate aggravating factor at sentencing.
License Suspension Runs on Its Own Track
A DUI arrest triggers an administrative license suspension handled by your state’s motor vehicle department, entirely separate from the criminal case. It moves fast. In many states the suspension takes effect within days of arrest, long before a judge hears the criminal charge. You can request a hearing to challenge it, but deadlines are tight, often 10 to 30 days from the arrest date.
First-offense administrative suspensions typically run 90 days to one year. Second and third offenses push suspensions to one to three years, and some states impose permanent revocation after enough repeat convictions.
Refusing the Breath or Blood Test
Every state has an implied consent law: by holding a driver’s license, you already agreed to submit to a breath, blood, or urine test if lawfully arrested for DUI. You can still refuse, but a first refusal brings a mandatory license suspension of roughly six months to a year, and in many states that refusal suspension is longer than what you’d get for failing the test. It applies whether or not the criminal DUI charge sticks.
Refusal can also be used against you at trial. Prosecutors argue it shows consciousness of guilt, and some states tack on additional fines or mandatory jail time for the refusal itself.
Ignition Interlock Devices
Thirty-one states and the District of Columbia require ignition interlock devices for all DUI offenders, including first-timers.4National Conference of State Legislatures. State Ignition Interlock Laws The device is a breathalyzer wired to your ignition that blocks the engine from starting if it detects alcohol. First-offense installations typically last six months to a year; repeat or high-BAC convictions can extend to two or three years. You pay for installation, monthly monitoring, and periodic calibration, which runs roughly $70 to $150 a month out of pocket.
The Fine Isn’t the Real Bill
The dollar figure printed on your sentencing order is a fraction of what a DUI actually costs. Add court fees, legal representation, program tuition, reinstatement fees, and the insurance spike, and first-time offenders commonly face a total in the range of $10,000 or more. The pieces:
- SR-22 filing. Most states require an SR-22 certificate proving minimum liability coverage. The filing fee is modest, typically $15 to $50; the damage is what it signals to your insurer.
- Insurance premium increases. A DUI can nearly double your auto premium. Surcharges commonly run 80% to over 100% during the first two years and taper over three to five. Most states require the SR-22 to stay active for three years, and any lapse restarts the license suspension clock.
- DUI education. Enrollment and tuition start around $75 to $250 and run higher for longer programs ordered after repeat or high-BAC convictions.
- Ignition interlock. At $70 to $150 a month for six months to a year, interlock alone can hit $900 to $1,800 on a first offense.
- License reinstatement fees. Vary by state, commonly $50 to $500.
- Legal fees. A DUI defense attorney typically charges $2,000 to $5,000 or more for a misdemeanor; felony cases cost considerably more.
Spread across three years, the insurance increase alone often exceeds everything else combined. It’s the expense that catches most people off guard because it never shows up in the courtroom.
If You Hold a CDL
A DUI conviction effectively ends your commercial driving work, at least temporarily, and the rule applies even if you were off duty in your personal vehicle. Federal law requires a minimum one-year CDL disqualification for a first DUI conviction. If you were hauling hazardous materials, the disqualification jumps to three years. A second DUI conviction brings lifetime CDL disqualification, though states may allow reinstatement after 10 years if you complete a rehabilitation program.2Office of the Law Revision Counsel. 49 USC 31310 – Disqualifications The federal BAC threshold for commercial drivers is 0.04%, so you can be well under 0.08% and still lose the CDL.5eCFR. 49 CFR Part 383 Subpart D – Driver Disqualifications and Penalties
Travel to Canada
Canada treats impaired driving as a serious crime, and a single DUI conviction from any country can make you inadmissible at the border. Since December 2018, Bill C-46 raised the maximum penalty for impaired driving to 10 years, reclassifying it as “serious criminality.”6Government of Canada. Convicted of Driving While Impaired You can apply for a Temporary Resident Permit for a specific trip, or, five years after completing your full sentence (including probation and fines), apply for criminal rehabilitation. For offenses before December 18, 2018, you may be deemed rehabilitated automatically after 10 years; that pathway does not apply to later offenses.
