Texas and Louisiana have declared state emergencies due to Harvey. These declarations
automatically waive select FMCSRs, including hours-of-service (HOS) regulations, for motor
carriers hauling resources to aid in restoration efforts. The declarations exempt FCMSR in every state along the motor carrier’s route as long as the final destination is with the declared disaster areas in Texas or Louisiana.
