Under current law, a truck with a mobile billboard trailer can move just a few inches and comply with regulations.
That effectively means the billboard can remain in the same general location -- give or take a few inches -- indefinitely.
A bill that would make it easier for city officials to regulate such billboards was approved Monday by the Assembly. Assemblyman Bob Blumenfield's bill gives cities the authority to regulate how far a parked vehicle must move after 72 hours.
"Mobile billboards are a plague that must be driven from our community,'' said the Woodland Hills lawmaker.
Blumenfield authored a related law that went into effect in January. That bill banned unhitched billboard trailers from being parked on public streets, but included a loophole that allowed billboard owners to hitch the advertisements to a truck and move them just a few inches.
It's the latest step in the city's crackdown on mobile billboards. Efforts have been mired in litigation and stringent requirements to post the ordinances at every entrance to the city, Blumenfield said.
The bill passed the Assembly with a 58-11 vote. It now moves to the Senate for consideration.
