A driver with a commercial driver’s license, or CDL, can operate trucks and other vehicles for commercial purposes. A temporary CDL driver works for a company as a substitute driver, a contractor, or a freelancer, without a permanent position. As a temporary CDL driver, your job duties depend on the needs of each client and the type of CDL license you hold. You may operate small trucks and make local deliveries, or you may drive large cargo loads longer distances that require you to stay overnight before returning home. Temporary CDL drivers may work a particular route for a set amount of time, or you may receive assignments on an on-call basis.
