Minneapolis has a very strange and archaic law that specifically prohibits red cars from being driven on Lake Street, one of the major routes in south Minneapolis. Needless to say this is not enforced and probably never has been within the lifetime of any poster here.
But if it ever was enforced for some bizarre reason and thus was challenged in court...what would be the reasoning if any to strike it down? After all there are plenty of laws restricting certain vehicles from certain roads, although those are based on size and weight requirements, and Minneapolis also restricts all vehicles except buses and taxis (but not rideshares) from a street in downtown. But those aren't as arbitrary as restricted based on the vehicle color. However is it really a First Amendment right to drive a red car on all public streets? I can see the argument but it sounds kind of weird.
Is there some other standard that would strike down this law?
Definitely not a first amendment violation. Can states ban someone from drinking water on a street? It's just a stupid law but not necessarily unconstitutional.
