Weather, Visibility & EmergenciesStandalone practice
A snowplow ahead is throwing snow toward the right shoulder and leaving a cloud that limits your view. What is the safest response?
Correct answer: Stay well back and wait until a safe, visible passing opportunity exists.
Why
Give a snowplow room to work. It may move much more slowly than other traffic and its blade can extend beyond its body. Never pass on its shoulder side. Stay patient when blowing snow or traffic makes passing unsafe.
