Montana Vehicle Inspection Rules & Safety Standards
Montana vehicle inspection requirements and safety standards can be confusing, especially since the rules vary by vehicle type and age. Unlike many states, Montana doesn’t require annual safety inspections for most passenger vehicles, but there are still key situations where you’ll need one.
As of 2026, the Montana Department of Justice Motor Vehicle Division enforces safety checks for certain vehicles, with exemptions for newer models and specific use cases. Here’s what you need to know to stay compliant and avoid fines.
Quick Answer
Montana vehicle inspection requirements and safety standards apply to most vehicles over 4 years old. Newer passenger vehicles are exempt from annual safety inspections. Commercial vehicles and rebuilt titles have stricter rules.
Inspections cover brakes, lights, tires, and other safety components. Fees typically range from $10 to $30.
