Hazardous Materials: California Meal and Rest Break Requirements
Notice of Administrative Determination of Preemption.
PHMSA finds that California's meal and rest break requirements create an unnecessary delay in the transportation of hazardous materials, and are therefore preempted with respect to all drivers of motor vehicles that are transporting hazardous materials. The agency also finds that the California meal and rest break requirements are preempted with respect to drivers of motor vehicles that are transporting Division 1.1, 1.2, or 1.3 explosive material and are subject to the attendance requirements of 49 CFR 397.5(a), because it is not possible for a motor carrier employer's drivers to comply with the off-duty requirement of the California rule and the federal attendance requirement. Finally, the California meal and rest break requirements are preempted as to motor carriers who are required to file a security plan under 49 CFR 172.800, and who have filed security plans requiring constant attendance of hazardous materials, because the California requirements are an obstacle to carrying out the requirements of 49 CFR 172.800 with respect to such motor carriers.
