United Truck Driving School has been training the nation's truck drivers since 1978. With two Southern California locations, our training includes all classes and combinations of vehicles. We offer Class A, Class A + P, and Class B CDL training. New classes start every two weeks and run on a continuous basis year-round. Programs are based on the number of hours completed. United's most popular format is the 40-hour per week full-time program. We recently added a night and weekend class at our San Diego campus to accommodate other schedules.
