License Suspension Duration Calculator
Estimate your driver's license suspension duration based on violation type, number of prior offenses, BAC level (if applicable), and whether a hardship/restricted license applies.
Primary Violation Type
-- Select Violation -- DUI / DWI – 1st Offense DUI / DWI – 2nd Offense DUI / DWI – 3rd Offense Reckless Driving Excessive Speeding (30+ mph over limit) Moderate Speeding (15–29 mph over limit) Hit and Run Point Accumulation (12+ points) Driving Without Insurance Drag Racing / Street Racing School Zone Violation Implied Consent Refusal (Breathalyzer)
BAC Level (Blood Alcohol Content, %)
Legal limit is 0.08% in most states. Enter 0 if unknown.
Number of Prior Suspensions / Revocations (last 10 years)
Was a Minor (under 18) Involved or Was Driver Under 21?
No Yes
Did the Violation Result in Bodily Injury or Property Damage?
No injury or damage Property damage only Bodily injury Fatality
Eligible for Hardship / Restricted License?
No Yes (work, medical, school driving only)
Is This a Commercial Driver's License (CDL)?
No – Standard License Yes – CDL Holder

#### Formula
Total Suspension Days = BaseDays × BAC_Multiplier + PriorOffenseAdd + MinorAdd + InjuryAdd + CDL_Add
- BaseDays: Statutory minimum suspension for the primary violation (e.g., 90 days for 1st DUI, 180 days for hit-and-run).
- BAC Multiplier: +50% if BAC ≥ 0.16% (aggravated DUI threshold).
- PriorOffenseAdd: +50% for 1 prior, +100% for 2 priors, +150% for 3+ priors (within 10 years).
- MinorAdd: +25% if a minor was involved or driver was under 21 (zero-tolerance law).
- InjuryAdd: +30 days (property damage), +50% (bodily injury), +100% (fatality).
- CDL_Add: +50% for commercial license holders per FMCSA federal standards.
- Hardship License: Does not reduce total suspension; mandatory minimum = 50% of total days before restricted privileges may begin.
#### Assumptions & References
- Base durations follow NHTSA Model Impaired Driving Law and AAMVA (American Association of Motor Vehicle Administrators) guidelines.
- BAC legal limit of 0.08% applies in all U.S. states; aggravated DUI threshold of 0.16% used per NHTSA recommendations.
- CDL holders are subject to stricter federal rules under 49 CFR Part 383 (FMCSA Commercial Driver's License Standards).
- Hardship/restricted license eligibility typically requires SR-22 insurance and, for DUI, an Ignition Interlock Device (IID).
- Actual suspension length varies significantly by state. This calculator provides a general national estimate and is not legal advice.
- Prior offenses lookback period assumed to be 10 years (varies by state: some use 5 or 7 years).
