Enhancements, in the context of DUI laws, refer to greater punishments or penalties that are levied to the sentences of some individuals that are convicted of driving under the influence (DUI/DWI). These are issued only under certain circumstances.
The circumstances under which DUI enhanced sentences are given vary from state to state. They generally include prior DUI convictions, high BAC levels, property damage, refusal to take field sobriety or chemical tests, endangerment of children, or infliction of bodily injury. A DUI sentence enhancement usually means stricter punishments or penalties in the form of long-term license suspension, higher fines, or mandatory jail time.
