A proposed Clark County ordinance would prohibit trailer-drawn billboards and limit the overall size of vehicles to 32 feet long and 8.5 feet wide.
The trucks would also be prohibited from operating in winds over 35 mph and from making U-turns.
The ordinance would also bar billboard trucks from parking in residential neighborhoods.
Clark County Commissioner Jim Gibson told the Las Vegas Sun that public safety concerns prompted the proposal. He said the commission wanted to implement minimum safety standards of operation, especially on congested roadways like the Las Vegas Strip.
The proposal includes a $500-per-truck annual licensing fee.
