Montana has secondary law enforcement for safety belt use, meaning that there must be another reason for stopping a vehicle other than noncompliance with safety belt laws before a violation can be charged. Although Montana ranks relatively high for overall seat belt usage among states with secondary law enforcement (76.9 percent in 2011 for all roads), NHTSA documentation shows that most states with a primary enforcement law have higher compliance rates.
Comprehensive Highway Safety Plan
Montana has established a variety of programs to encourage safety belt use and proper utilization of child safety restraints. New strategies focus on the establishment of a primary safety belt law and targeted enforcement and education for low belt use populations.
