DUI Lookback and Felony Checker

Does a Prior DUI Still Count?

States count prior DUI convictions only within a lookback period, often 5 to 10 years, though some count them for life. Pick your state and enter how long ago your prior conviction was to see whether it still counts, and when an offense becomes a felony.

How Lookback Periods Work

The lookback window decides whether a new offense is charged as a repeat offense, which carries more jail time, longer suspensions and, past a point, a felony. States measure the window differently (from conviction, from the offense date), so the state page gives the exact rule and statute.

Frequently Asked Questions

What Is a DUI Lookback Period?

It's how far back a state looks for prior DUI convictions when deciding whether a new offense counts as a second or third offense. Outside the window, a new offense is usually treated as a first for sentencing, though some states never stop counting.

Does a DUI From Another State Count?

Many states count out-of-state convictions for similar offenses. Check your state's page and its statute.
