In the United States, the legal situation varies from state to state. In California, residents must pay a state fee of $1,000.[clarification needed] The states of Colorado, Massachusetts, and Wisconsin ban such memorials. Other states impose specific requirements.[6][7] In Birmingham, Alabama, roadside memorials have been removed from Interstate highways.[8] Some people view unauthorized street memorials as illegal and think they constitute the taking of public property for private purposes, and are also a distraction and therefore dangerous to the motoring public. Others think they serve as a sort of public service announcement that reminds drivers to be careful and drive safely, and are no more distracting than any other roadside advertisement. Others find them tacky and disturbing.
Using a Christian cross as a memorial along a public highway can be seen as an illegal endorsement of religion and has been challenged in a growing number of lawsuits by secular groups concerned about the separation of church and state.
