Penalties vary with the country or state in which the offence occurs. There may be additional or "enhanced' penalties based on the number of prior drunk driving convictions, the blood alcohol level at the time of arrest, whether there are children or other passengers in the vehicle, whether intoxicants other than alcohol (marijuana, cocaine, methamphetamine, etc.) are involved, and if the drunk driving incident caused property damage, injury or death.

Typical penalties can include

• Jail or prison time
• Monetary fines
• Forfeiture of the drivers license
• Mandatory attendance at alcohol counselling or rehabilitation sessions, Alcoholics Anonymous meetings, and/or victim impact panels (where victims of drunk drivers talk about their experiences)
• Community service, sometimes while wearing a vest or other garment identifying them as a convicted drunk driver
• Requirements to abstain from consuming alcohol or other contraband drugs, possibly enforced by an electronic monitoring bracelet
