I-80 Poconos area in Pennsylvania...stranded vehicles

It would seem to me, that the authorities, knowing that the pattern is repeated over and over with truckers on major routes during winter storms, would shut them down to the truckers. That's what we do here in California. The Highway Patrol and Department of Transportation holds all trucks from the California/Nevada state line to the East and the 2,000' elevation to the West until the weather improves.
No, the truckers don't like it, but they expect it and can plan for it because it's the policy.
