A Georgia state law requires the use of contoured rear-fender mudguards on trucks and trailers operating within Georgia state lines. The statute further makes it illegal for trucks and trailers to use straight mudguards. In approximately thirty-five other states, straight mudguards are legal. Moreover, in Florida, straight mudguards are explicitly required by law. There is some evidence suggesting that contoured mudguards might be a little safer than straight mudguards.

Discuss whether this Georgia statute violates any constitutional provisions.
