When Does a DUI Become a Felony?

Multiple Prior Offenses

The single most common path to felony DUI is repeat offending. In most states a third DUI within 7 to 10 years is a felony; a few states (New York, Texas) treat the third as a felony regardless of timing. A fourth offense is felony in nearly every state and often carries a 2-to-5-year prison minimum.

Prior convictions count even if expunged, sealed, or set aside in nearly every state for sentencing-enhancement purposes.

DUI Causing Injury

DUI with serious bodily injury is a felony in every state. Sentences range from 2 to 10 years in prison plus restitution. DUI-related vehicular manslaughter or homicide carries 4 to 25+ years (life without parole in some states for repeat offenders or extreme aggravators).

The injury does not have to be permanent — broken bones, concussions, and lacerations all qualify in most jurisdictions.

Child Endangerment

Driving impaired with a minor (typically under 14, sometimes under 16 or 18) in the vehicle triggers a felony enhancement in over 30 states. The charge is sometimes brought as a separate count of felony child endangerment in addition to the DUI.

Driving on a Suspended License

DUI while driving on a license already suspended for a prior DUI is a felony in Florida, Oklahoma, and many other states. This is one of the easiest ways to turn a 'simple' first DUI into a multi-year prison sentence.

Extreme BAC

Some states (Arizona, Indiana, others) make 'extreme DUI' (BAC 0.15 or 0.20+) a separate elevated charge with mandatory minimum jail and felony exposure on a second occurrence.

DUI With Hit-and-Run

Leaving the scene of an accident while impaired is felony in most states even on a first offense. Combined charges (DUI + felony hit-and-run + injury) can carry 10 to 30 years in prison.

Felony Consequences Beyond Prison

Permanent criminal record visible on every background check. Loss of voting rights (varies by state). Loss of right to own or possess firearms (federal and state). Loss of professional licenses (medical, legal, education, finance). Immigration consequences: removable offense for non-citizens. Difficulty obtaining housing, credit, and employment for life.

Felony DUI is one of the few felonies that virtually never gets expunged — most states either prohibit expungement entirely or require 10–20 year waiting periods.

Defending a Felony DUI

Felony DUI cases require an experienced criminal defense attorney with DUI expertise — never a public defender alone if you can avoid it. Defense priorities include: challenging the prior convictions used for enhancement (constitutionality, validity of waivers), aggressive motion practice on Fourth Amendment issues, and negotiating reductions to misdemeanor wet reckless or pre-trial diversion where available.
