In the 1950s, Illinois enacted legislation requiring trucks to have curved mud flaps. There was no federal law about mud flaps at the time, but the Illinois statute was enacted because state legislators asserted that the curved mud flaps were more effective in preventing accidents than the straight mud flaps. Several trucking companies brought suit, because the Illinois statute conflicted with the laws of other states that required straight mud flaps. Was the Illinois statute constitutional?
A. No because it violated the Commerce Clause.
B. Yes because it did not discriminate against out of state truckers.
C. No, the Supremacy Clause does not allow conflicting state legislation.
D. Yes, there was no federal statute so the state statute did not violate the Supremacy Clause.
