What this tool does
The DUI Penalty Estimator provides general educational information about the typical range of penalties associated with a DUI (Driving Under the Influence) or DWI (Driving While Intoxicated) charge across all 50 US states.
**IMPORTANT: This tool does not provide legal advice.** The estimates shown are general ranges based on typical state statutes and are intended only to help people understand the potential consequences of a DUI charge. Actual penalties depend on many factors including your specific circumstances, prior criminal history, the prosecutor assigned to your case, plea negotiations, and judicial discretion.
If you are facing a DUI charge, consult a licensed DUI defense attorney in your state immediately.
Understanding DUI penalties
A DUI conviction typically carries multiple types of penalties that compound on each other. Understanding the full scope of potential consequences helps you appreciate why legal representation is so important.
**Criminal penalties** include fines, jail time, and probation. These are set by state law but judges often have discretion within statutory ranges. Aggravating factors — such as a high BAC, causing an accident, or having a minor in the vehicle — can push penalties toward the higher end or add mandatory minimums.
**Administrative penalties** are separate from criminal proceedings and are imposed by your state's motor vehicle authority (DMV or equivalent). License suspension can begin immediately after arrest in many states, even before a conviction, through a process called Administrative License Suspension (ALS).
**Financial consequences** extend far beyond the fine itself. Court costs, legal fees, alcohol education programs, ignition interlock device installation and monthly fees, towing and impoundment, and dramatically increased insurance premiums can easily multiply the total cost of a DUI several times over.
Factors that affect DUI penalties
No two DUI cases are identical. Courts consider many factors when determining penalties:
**BAC level:** Most states set 0.08% as the legal limit, but many have enhanced penalties for BAC levels at or above 0.15% or 0.16%, often called "aggravated DUI" or "super DUI." A BAC over 0.20% typically triggers the most severe penalties.
**Prior offenses:** A first offense usually carries the lowest penalties, often with options for diversion programs. Second and subsequent offenses face dramatically higher mandatory minimums, longer license suspensions, and mandatory ignition interlock requirements.
**Accidents and injuries:** If your DUI involved an accident, property damage, or injuries to others, charges may be elevated to felony level. A DUI causing death can result in vehicular manslaughter or second-degree murder charges.
**Minors in the vehicle:** Driving under the influence with a passenger under 18 is treated as an aggravating factor in virtually every state, often doubling fines or adding mandatory jail time.
**Commercial drivers:** CDL holders face a 0.04% BAC limit and typically lose their commercial license for a year on a first offense — potentially ending a driving career entirely.
**Cooperation with law enforcement:** Refusing a breathalyzer test triggers automatic license suspension in all states under implied consent laws, and refusal can be used as evidence in some states.
SR-22 insurance explained
SR-22 is not an insurance policy — it is a certificate of financial responsibility that your auto insurance company files with your state's DMV on your behalf. Most states require SR-22 filing for a period of 3 years following a DUI conviction, though some states require up to 5 years.
Because SR-22 signals to insurers that you are a high-risk driver, your insurance premiums will increase substantially. The average increase after a DUI ranges from \$800 to \$2,500 or more per year, depending on your state, age, driving history, and the insurance company. Some insurers will drop you entirely, forcing you to seek coverage through high-risk specialty insurers.
If your SR-22 lapses — for example, if you stop paying premiums and your policy is cancelled — your insurer is required to notify the state, which can result in your license being suspended again. Maintaining continuous coverage throughout the SR-22 period is essential.
Some states use the term "FR-44" instead of SR-22, particularly Florida and Virginia, which require higher minimum liability limits.

FAQs
Q: How accurate are these penalty estimates? A: The estimates reflect typical statutory ranges for each state as of 2024-2025. They are general educational information and should not be relied upon for legal planning. Actual penalties depend heavily on the specific facts of your case, your attorney, and the court. Use these figures only to understand the general scope of consequences.
Q: What is the difference between a DUI and a DWI? A: DUI (Driving Under the Influence) and DWI (Driving While Intoxicated or Impaired) are terms used interchangeably in different states. Some states use one term, some use the other, and a few use both to distinguish between alcohol and drug impairment or between misdemeanor and felony levels. Legally, they are equivalent in most contexts.
Q: Can a DUI charge be reduced or dismissed? A: Yes, in many cases. An experienced DUI attorney can challenge the legality of the traffic stop, the accuracy of the breathalyzer or field sobriety tests, chain of custody for blood samples, and other procedural issues. In some states, first-time offenders may be eligible for diversion programs that result in dismissal after completing certain requirements.
Q: How long does a DUI stay on my record? A: It varies significantly by state. In many states, a DUI stays on your driving record for 10 years, meaning a second offense within 10 years is treated as a second DUI. Some states have lifetime lookback periods for enhanced penalties. A DUI conviction on your criminal record may be permanent unless you pursue expungement, which is available in some but not all states.
Q: Do I need an attorney for a DUI charge? A: While you have the right to represent yourself, a DUI charge is serious and the legal process is complex. A qualified DUI defense attorney knows local courts, prosecutors, and the technical aspects of DUI law that can make a significant difference in outcomes. Even for a first offense, an attorney may be able to reduce charges, negotiate plea agreements, or identify procedural violations that could result in dismissal.
Q: What is an ignition interlock device and who has to get one? A: An ignition interlock device (IID) is a breathalyzer connected to your vehicle's ignition. You must blow into it before the car will start, and periodically while driving. If it detects alcohol above a threshold (typically 0.02%), the vehicle will not start or will signal a violation. Many states require IIDs for all DUI convictions, while others require them only for repeat offenses or high-BAC cases. The cost is typically \$70–\$150 for installation plus \$60–\$100 per month for monitoring.
Q: Will a DUI affect my job or professional license? A: Potentially, yes. Many employers conduct background checks and a DUI conviction may affect employment, particularly in jobs requiring driving, working with children, holding security clearances, or in licensed professions such as law, medicine, nursing, teaching, or commercial transportation. Professional licensing boards may impose additional sanctions beyond criminal penalties.
