Snowmobile helmets help prevent serious head injury.

DOT approved helmet
  • Benefits
    • Snowmobile helmets are designed to protect your head and face in collisions or falls, from tree branches while riding, from the cold, and from loud noise.
    • Unlike motorcycle helmets, snowmobile helmets have vents that you can open or close prevent fogging.
    • Snowmobile face shields have a double lens to resist fogging. Some face shields have built-in defrosters that plug into an outlet on the snowmobile.
    • Snowmobile helmets have a foam liner that may offer some degree of flotation if you fall into freezing water. Wearing a helmet also provides insulation to retain body heat around your brain.
  • Selection
    • Make sure your helmet fits snugly, fastens securely, and doesn’t move or feel loose. Try on helmets over riding headgear.
    • Replace your helmet every five years. Made of fiberglass or plastic, helmets become brittle over time.
    • Place a strip of reflective tape on your helmet for extra visibility after dark.
    • Don’t paint your helmet. Solvents in the paint can weaken the shell.
    • If you are operating your snowmobile in the United States, select a helmet with a safety-approval label from the Department of Transportation (DOT).
