The state Assembly voted to approve a bill last week that would give Los Angeles officials more power to crack down on mobile billboard advertisers.
AB 1298 sponsored by Assemblyman Bob Blumenfield, D-Van Nuys, would give the city the authority to penalize mobile billboard advertisers who skirt towing and impound laws.
State law allows vehicles to park in the same place for up to 72 hours.
Mobile billboards hitched to cars, trucks, motorcycles or even bikes, have abused the law by moving a matter of inches to start a new 72-hour cycle and essentially keep billboards in the same location.
The bill, which still needs to be signed by Gov. Jerry Brown, gives cities the authority to draft ordinances specifying the minimum distance a vehicle must move to avoid being towed after 72 hours.
The bill would also broaden the definition of a mobile billboard to include any device that transports a sign for the purpose of advertising.
