According to Montana DUI laws, individuals can fight to keep their driver's license and to avoid jail time and fines. It is difficult to do this if you have been charged with DUI. The best recourse available is using a specialized and experienced Montana DUI lawyer.

Montana Blood Alcohol Concentration Laws

The Montana BAC level is .08 percent. If you are at or over this number, you are in violation of Montana DUI laws and will face charges. Likewise, if you refuse to take the Preliminary Alcohol Screen testing (PAS test) you will be charged with DUI as well. You do not have to have a high BAC to be charged: a police officer may arrest and charge you with DUI if you fail sobriety tests or appear to be under the influence or unable to control your vehicle:

  • Driving patterns can be used
  • Performance in field sobriety tests is used
  • Physical appearance, such as blood shot eyes

Also keep in mind that Montana DUI laws also state that if you are under 21 years of age and have a BAC level of .02 or higher, you will be charged with DUI. If your BAC level is .18 you will face enhanced penalties. An ignition interlock device may be required. Increased fines and up to a 12 month period of driver's license revocation may be required.

If you have failed any of these tests, contact a Montana DUI lawyer right away to fight the charges.

Implied Consent Laws

In the state of Montana, driving on roadways means you are agreeing to take a chemical test if a police officer requires one. This falls under the state's Implied Consent laws.

If you refuse to take a chemical test, you will have your license immediately suspended for 6 months. If you refuse more than one time for subsequent arrests, you will lose your driver's license for at least 1 year and there is the potential of a required ignition interlock device being required.
