The Section 13(b)(1) overtime exemption does not apply to employees not engaged in “safety affecting activities”, such as dispatchers, office personnel, those who unload vehicles, or those who load but are not responsible for the proper loading of the vehicle. Only drivers, drivers’ helpers, loaders who are responsible for proper loading, and mechanics working directly on motor vehicles that are to be used in transportation of passengers or property in interstate commerce can be exempt from the overtime provisions of the FLSA under Section 13(b)(1).
