If you come up on several snowplows clearing a freeway, you should NOT

The question is about what you should NOT do. On freeways, several snowplows may be staggered across the road, clearing all lanes at the same time by passing a ridge of snow from plow to plow. Do not try to pass between them. This is extremely dangerous because there is not enough room to pass safely, and the ridge of wet snow can throw your vehicle out of control.
