 In November 2019, the California Trucking Association, representing about 70,000 truck drivers in the state, filed suit in the United States District Court for the Southern District of California, challenging both the California Supreme Court "Dynamex" ruling and AB5.The Association argues that many of the represented drivers had opted to be independent contractors after having been employeed drivers, as this allows them to set their own schedules and otherwise profit from owning their own vehicle.Enforcement of AB5 would force them to be treated as employees and lose these benefits, the Association argued.
