Always exceed the speed limit to avoid getting rear ended. If traffic is stopped on the Interstate, it is okay to drive on the shoulder of the road and get off at the next exit. If you change your mind about getting on the Interstate or miss the exit, use the shoulder of the road to back up. That's what it's for. Never expect salt on the road when it snows.
Salt costs money.
It's every one for themselves under hazardous conditions, another good reason to own a 4-wheel drive vehicle. Never stay home because you don't know how to drive in snow. Get out as soon as possible and see how bad it is. Semi trucks with double trailers should always drive in the left-hand passing lane as they are in a bigger hurry than everyone else. Gasoline tankers should drive as fast as possible through urban areas so they will endanger public safety for a shorter period of time.
