What is an important consideration when following a snowplow?

Leaving plenty of space when following a snowplow is crucial because these vehicles may spread sand or gravel on the road to improve traction during icy conditions. This action can create a hazardous situation for vehicles that are closely following. If there isn’t enough space, a driver may find it difficult to react in time to any potential changes in the road conditions or obstacles caused by the sand or gravel being deposited. Adequate distance allows drivers to maintain control, ensuring safer navigation in potentially slippery or hazardous situations that may arise after a snowplow passes.

The other considerations, while they could be relevant in different contexts, do not specifically address the unique challenges posed by snowplows and the conditions they create. For instance, while snowplows may make sudden stops, they are primarily focused on clearing the road, and the spreading of materials necessitates extra caution regarding following distance.
