Most campuses have private roads. As such, they can enforce their policies even on the roadway. Smokers have the ability to drive on other roads, etc. to not violate the policy. It has been upheld in state and federal courts.

I happen not to agree with the policy, since it is extreme and putative. But they never asked my opinion when they did it. One more example of schools being forced to play mommy and daddy instead of focusing on education.
