Snowmobile group at night using CSS lights
  • Group riding requires good communication and visual contact.
  • Visual communication requires proper spacing.
  • To keep the group together, the trail leader should slow down or wait on the opposite side of a crossing when a stop is required. After crossing, the leader stops or slows the group to ensure that everyone knows the correct route.
  • Hand signals should be used at all times when riding. When riding with a group, you give hand signals to the person behind you.
    • Don’t make sloppy signals.
    • Make sure the person behind you can see your signals.
  • Two-way headsets installed in helmets are useful for voice communication and are an effective way for the trail leader and the sweep to communicate.

Communication Safety System

Another way to signal other snowmobilers is with a Communication Safety System (CSS). The CSS is a lighting system that attaches to the left handlebar or the left side of the hood on your snowmobile. You select the light that is appropriate for your situation.

  • Yellow light: More snowmobiles are following you.
  • Green light: You are the last snowmobile in the group, or you are riding alone.
  • Flashing hazard light: You or another rider needs assistance.
