Which check should a commercial driver perform continuously while the vehicle is moving?
Correct answer: C – Watch the gauges and use the senses for signs of trouble
During a trip, drivers should monitor gauges and use sight, hearing, smell, and feel to detect possible trouble. Physical checks of tires, wheels, brakes, lights, trailer connections, coupling devices, and cargo securement should be completed when the vehicle is safely stopped. Continuous monitoring can provide early warning of a developing problem.
