Safety Laws in Montana
Riders under 18 years old must wear a helmet.
There is no statewide bicycle helmet law, but the Montana Department of Transportation (MDT) strongly recommends you wear one.
Headlights must be used:
- 30 minutes after sunset until 30 minutes before sunrise.
- When visibility, due to foul weather, is reduced to 500 ft or less.
Daytime headlights are required in Montana. A modulating headlight is permissible.
When riding at night, your bike must be equipped with a front white light visible from 500 ft away, and a red rear light that is also visible from 500 ft.
As of October 2013, there are no statewide laws prohibiting cell phone use or texting while driving. However, several municipalities have implemented their own bans on distracted driving:
- Billings: Prohibits texting and the use of handheld phones
- Helena: Prohibits the use of handheld phones (this also applies to bicyclists)
- Missoula: Prohibits texting (this also applies to bicyclists)
- Whitefish: Prohibits texting and the use of handheld phones
- Hamilton: Prohibits handheld devices
- Bozeman: Prohibits texting and hand held phones
- Great Falls: Prohibits texting and hand held phones
- Columbia Falls: Prohibits texting and hand held phones
- Butte-Silver Bow and Anaconda-Deer Lodge: County wide bans on the use of handheld phones
- Kids under 6 years old or weighing less than 60 lbs must ride in a federally-approved safety seat or booster.
- All other riders, regardless of age, must use a seat belt.
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.
