In Montana, charges of Driving Under the Influence of Alcohol or Drugs (“DUI”) have criminal consequences including jail time, fines, alcohol and drug treatment, and suspension of your driver’s license.  If you are convicted of a DUI, you will be prohibited from entering Canada and potentially other countries. An Aggravated DUI has even harsher penalties. The trial lawyers at Blackford Carls P.C. are experienced DUI defense attorneys, and will zealously defend your DUI.

We aggressively defend DUIs and work to protect your Constitutional rights. The Montana and United States Constitutions prohibit law enforcement from stopping and investigating you for DUI without specific evidence.  If law enforcement improperly searches and seizes you, any evidence they obtained would be inadmissible and your charges may be dismissed. The experienced trial lawyers at Blackford Carls P.C. make sure that law enforcement also conducted the investigation and the tests properly.  If the investigation and tests were improper, we will fight to exclude the improper evidence from Court.

The experienced trial lawyers at Blackford Carls P.C. fight DUI charges to get you the best possible result.
