Commercial Driver's License

Answer: D - Commercial drivers must be aware of the conditions that can lead to wet brakes. Brakes can become wet when driving in heavy rain, driving through puddles on the road, or when driving on melting snow and melting ice. Wet brakes can result in reduced or complete loss of braking power. Wet brakes can also cause the vehicle to pull to one side, which can be dangerous to other vehicles and can also lead to trailers jackknifing.
