Final answer:
Locking the brakes on a vehicle results in a loss of control over the speed and direction of the vehicle.
Step-by-step explanation:
When you lock your brakes, you lose the ability to control the speed and direction of your vehicle.
Locking the brakes means that the wheels stop rotating and slide on the road surface. This results in a loss of traction, making it difficult to steer the vehicle or maintain control.
To prevent locking the brakes, it is important to apply steady pressure on the brake pedal instead of fully depressing it.
