LOS ANGELES - Truck drivers' claims arising from the charging and markup of liability insurance are preempted, but they may recover under the California unfair competition law (UCL) based on a motor carriers' charging of workers' compensation fees, an appeals court held in an opinion published Sept. 20 (Salvador Rodriguez, et al. v. RWA Trucking Co. Inc., No. B241727, Calif. App., 2nd Dist., Div. 4).
