Georgia Commercial Driver License Practice Test

What action should you take if you're experiencing wheel lockups due to wet brakes?

1. Release the pressure on the brake

2. Increase your speed to regain control

3. Pull the brake handle immediately

4. Shift into a lower gear

The correct answer is: Release the pressure on the brake

Releasing the pressure on the brake is the correct action when experiencing wheel lockups due to wet brakes. When brakes become wet, they can lose their effectiveness and may cause the wheels to lock up, which can lead to a loss of control of the vehicle. By releasing the brake pressure, you allow the wheels to start rolling again, which helps regain traction and steering control. Increasing your speed might seem like a way to regain control, but it actually exacerbates the issue by potentially increasing the slide or loss of control. Pulling the brake handle immediately can lead to further wheel lockup, worsening the situation and making it harder to control the vehicle. Shifting into a lower gear could provide some engine braking, but it doesn't directly address the immediate issue of locked wheels, which is why simply releasing brake pressure is the most effective approach.
