Final answer:
A safe following distance on a snowmobile depends on the speed, terrain conditions, and the rider's experience level, but a recommended gap is a minimum of a two-second space.
Step-by-step explanation:
When following another snowmobile, it is essential to maintain a safe distance to prevent collisions, especially due to varying snow and ice conditions which can affect stopping distances. An ideal distance isn't specifically mentioned, but a good rule of thumb would be to allow for a two-second gap between you and the snowmobile in front of you. This gap should be increased in poor visibility, slippery conditions, or when following larger vehicles. Factors to consider include the snowmobile's speed, the terrain conditions, and the rider's experience level.
