Just hours before California’s new gig-work law, AB5, is set to take effect, a federal judge issued a temporary restraining order blocking the state from enforcing it upon truck drivers. U.S. District Judge Roger Benitez, in a five-page order on New Year’s Eve, discussed the California Trucking Association’s contention that AB5 was preempted by a 1994 federal statute that prohibits states from making laws that affect the price, route or service of freight-hauling motor carriers.
