Are exceptions to Hours of Service rules made for adverse weather conditions?
A driver may exceed the 10- or 11-hour driving limit by no more than two hours due to adverse weather conditions. However, the adverse weather exception doesnt allow a driver to exceed the 14- or 15-hour daily limit or the 60- or 70-hour weekly limit. In order to use an adverse weather exemption, the driver must be involved in a trip that could normally have been completed without an HOS violation and that the adverse driving conditions developed after the driver began the trip.
