Commercial Driver's License

Answer: C - Commercial drivers should be aware that wheels locking up, loss of braking power, pulling to one side and/or jackknifing are often caused by wet brakes. Brakes on commercial vehicles can become wet when driven in periods of heavy rain or if the vehicle is driven through standing water. Generally, wet brakes will first be noticed as a "grabbing" sensation or as a loss of braking power. In either case, the driver should pull over when safely able to do so and allow the brakes to dry out.
