Expect multiple-choice questions drawn from the state's CDL manual, covering topics such as pre-trip inspection, shifting, seeing and communicating, space management, emergency maneuvers, skid recovery, vehicle systems, cargo securement, passenger and hazardous materials awareness, hours of service, accident procedures, and railroad crossings.
