How to Use the DUI Penalty Estimator
A DUI charge is one of the most serious traffic-related offenses, carrying significant financial, legal, and personal consequences. This DUI penalty estimator provides general guidance on what you might expect based on your state, BAC level, and prior record — so you can prepare before meeting with an attorney.
Step 1: Select Your State
DUI penalties vary dramatically by state. California imposes mandatory minimum fines and IID requirements, while Texas has a range of penalties that increase sharply for repeat offenders. Select your state from the dropdown to see state-specific penalty ranges. If your state isn't listed, the "Other State (General)" option provides typical national averages.
Step 2: Enter Your BAC Level
Your blood alcohol content (BAC) at the time of arrest significantly affects penalties. The standard legal limit is 0.08% in all U.S. states. BAC levels of 0.15% or higher trigger enhanced penalties in most states, often doubling minimum fines and requiring IID installation. Levels above 0.20% may be charged as aggravated DUI with mandatory minimum jail time.
Step 3: Indicate Prior Offenses
Prior DUI convictions within the past 5–10 years (lookback period varies by state) are the biggest factor in DUI sentencing. A first offense might carry a $500–$2,000 fine and probation. A second offense typically doubles or triples fines and adds mandatory jail time. A third offense is often charged as a felony with potential prison sentences of 1–5 years.
Understanding Your Results
The results show typical fine ranges, license suspension periods, potential jail time, ignition interlock device (IID) requirements, and estimated insurance impact. The total cost estimate includes fines, court costs, attorney fees, SR-22 insurance, and IID installation — all real costs that most people underestimate. A typical first-offense DUI ends up costing $10,000–$25,000 total when all costs are factored in.

DUI (Driving Under the Influence) and DWI (Driving While Intoxicated) refer to the same offense in most states. Some states use one term, others use both with different severity thresholds.
How does a prior DUI affect penalties?
Prior DUI convictions dramatically increase penalties in every state. A second DUI typically doubles fines and minimum jail time. A third offense often triggers felony charges with mandatory prison sentences.
Will a DUI affect my insurance?
Yes — significantly. Most insurers will increase your premium 30-100%+ after a DUI. Many require an SR-22 filing for 3 years. Some carriers will cancel your policy entirely.
What is an ignition interlock device?
An ignition interlock device (IID) is a breathalyzer connected to your car's ignition. You must blow a legal BAC reading before the car starts. Most states require IIDs for DUI convictions, especially for elevated BAC or repeat offenses.
