Drink Driving Calculator (DUI Penalties & License) USA

DUI/DWI penalty data sourced from the National Highway Traffic Safety Administration (NHTSA), Driving Under the Influence (DUI) federal standard under 23 U.S.C. § 158, and state-level DUI/DWI statutes across all 50 U.S. states.
The standard legal Blood Alcohol Content (BAC) limit is 0.08% for drivers 21+ in all 50 states. Commercial drivers (CDL) face a 0.04% limit under 49 CFR Part 382. Drivers under 21 are subject to zero-tolerance laws (BAC ≤ 0.02%) in most states.
Enhanced penalties ("Aggravated DUI") apply in most states at BAC ≥ 0.15%. A 3rd or subsequent DUI conviction is a felony in most jurisdictions, carrying potential prison sentences exceeding one year.
All states have implied consent laws — refusing a BAC test results in automatic license suspension (typically 6–12 months) regardless of conviction. Ignition Interlock Devices (IID) and SR-22 insurance filings are commonly required for license reinstatement.
A DUI conviction typically remains on your driving record for 5–10 years and may affect employment, insurance rates, and professional licensing.
