Safe DrivingQuestion 43 of 120
You have just driven through deep standing water and your brakes feel weak. What should you do?
a.Stop immediately and wait for the brakes to air dry
b.Drive slowly while applying light pressure to the brakes to generate heat and dry them out
c.Pump the brake pedal rapidly while accelerating
d.Set the parking brake while rolling
Explanation
Light steady pressure while moving slowly creates the friction heat that dries wet linings and restores braking. Waiting can leave the brakes wet, rapid pumping while accelerating does not create sustained heat, and applying the parking brake while rolling can lock the drive wheels.
