Safety Laws in Montana

Helmets
Motorcycles
Riders under 18 must wear a helmet.
Bicycles
There is no statewide bicycle helmet law, but the Montana Department of Transportation (MDT) strongly recommends you wear one.
Headlights
Vehicles
Headlights must be used:
- One half-hour after sunset until one half-hour before sunrise.
- When visibility, due to foul weather, is reduced to 500 feet or less.
Motorcycles
Daytime headlights are required in Montana. A modulating headlight is permissable.
Bicycles
When riding at night, your bike must be equipped with a front white light and a red rear light that are both visible from 500 feet.
Cell Phones and Texting
As of October 2011, there are no statewide laws prohibiting cell phone use or texting while driving. However, several municipalities have implemented their own bans:
- Billings―Prohibits texting and the use of handheld phones
- Butte―Prohibits the use of handheld phones
- Helena―Prohibits the use of handheld phones
- MIssoula―Prohibits texting (this also applies to bicyclists)
- Whitefish―Prohibits texting and the use of handheld phones
Montana Child Car Seat Laws
- Kids under six or weighing less than 60 pounds must ride in a federally-approved safety seat or booster.
- All other riders, regardless of age, must use a seat belt.
If you're in the market for one, you can shop online for a child car seat at any time. When ordering, be sure the car seat matches your child's height, weight and age.
Reporting Drunk or Dangerous Drivers
Dial 911 if you suspect a driver of being drunk or unfit to drive. Provide the vehicle's license plate number, make, model, location and travel direction.
In a non-emergency situation, you may report someone you suspect of being unfit to drive to the Montana Motor Vehicle Division. The more information you can relay about the individual and your relationship to that individual, the better.
