What factor significantly increases the risk of accidents while snowmobiling?

Operating at high speeds significantly increases the risk of accidents while snowmobiling because higher speeds reduce the operator's ability to react to sudden obstacles, changes in terrain, or other hazards on the trail. When traveling quickly, the snowmobile's stopping distance increases, which can lead to collisions if the operator encounters something unexpected. Additionally, high speeds can result in loss of control, particularly on uneven surfaces or in poor visibility conditions, heightening the likelihood of crashes. Therefore, recognizing the dangers associated with speed is crucial for snowmobile operators to ensure their safety and the safety of others on the trail.
