Is It Safe to Pass a Snowplow?
Keeping safe around snowplows:
Be extremely cautious when passing a snowplow. They can be moved sideways by drifts and hard snow pack.
Stay back at least five car lengths behind the plow to be clear of snow fog and sanding material that can reduce your visibility.
Know where the snowplow is on multi-lane roadways, e.g., in either lane, on the shoulder, highway ramps and authorized vehicle only crossovers.
