Final answer:
It is unsafe to pass between several snowplows clearing a freeway. One should stay well back from the plows to avoid hazardous conditions. Moving to another lane is only safe if the lane is clear of snow and ice and the plows are not occupying it.
Step-by-step explanation:
When you come upon several snowplows clearing a freeway, you should NOT attempt to pass between them. This action can be extremely dangerous as snowplows often create a blind spot for drivers, and the road in between may not be cleared of snow and ice. Instead, it's essential to stay well back of the snowplows, as the plowed snow and debris can create a hazard if you follow too closely. Moving to another lane might be a safe option, but it depends on the lane conditions and whether it is clear of snow and ice. If the plows are occupying all lanes, it's safest to stay behind them at a safe distance until you can pass safely.
