Put the big rigs on the shoulder or anywhere except in the lanes of traffic. As soon as a winter weather WARNING is issued, off the road they go. We got every plane out of the sky on 9/11, we ought to be able to get big rigs on the side of the road too.
The real solution is to get all the private vehicles off the freeways. At the FIRST winter storm warning, you could all pull over to the shoulder and park. Leave the lanes to the trucks and emergency vehicles.
You see how stupid that sounds. It sounds just like saying"get all the trucks off the road"
Perhaps the real solution is for the taxpayers to fund more places to park, with facilities, for ANYONE to pull off the road. Imagine sitting in your car for 6-8 hours without any place to pee.
