Impaired Driving
Driving under the influence (DUI) of alcohol, drugs or both is more than illegal—it can be deadly.
In Montana there are a number of laws related to impaired driving, but here are a few basics:
- At this time, the alcohol concentration limit in Montana is .08, with the number referring to grams of alcohol per 100 milliliters of blood or grams of alcohol per 210 liters of breath. For drivers under the age of 21 it is .02.
- Drivers in Montana are considered to have given consent to blood or breath tests to determine the presence of alcohol or drugs. An arrested person may refuse to submit to such a test, but Montana law then allows a peace officer to seize the driver's license. The license may then be suspended or revoked and the length of the suspension depends on whether it is a first refusal or second or subsequent refusal.
- The penalties for a first-offense drunk-driving conviction include up to six months in jail and a fine of up to $1,000. Parts of the imprisonment may be suspended, pending the completion of a court-ordered chemical dependency program.
- Vehicles may be forfeited on the second or subsequent DUI.
- A fourth or subsequent DUI is a felony.
The Montana DUI statutes begin at 61-8-401 of the Montana Code Annotated
