When a DUI is a felony.

A PA DUI is a felony when it's a third-or-subsequent Highest BAC / refusal offense, any fourth offense, or any DUI that causes serious bodily injury or death (Aggravated Assault by Vehicle / Homicide by Vehicle While DUI). Felony DUI carries state prison and a permanent felony record.
