Final answer:
In an emergency situation, the proper way to use ABS is to firmly apply constant pressure on the brake pedal to prevent the wheels from locking up and skidding.
Step-by-step explanation:
In an emergency situation, the proper way to use ABS (anti-lock brake system) is to firmly apply constant pressure on the brake pedal. ABS is designed to prevent the wheels from locking up and skidding, allowing for better control of the vehicle during emergency braking.
When the ABS system detects that a wheel is about to lock up, it automatically modulates the brake pressure to that wheel. This prevents the wheel from skidding and allows the driver to maintain steering control.
It's important to note that ABS should be used in conjunction with good driving techniques, such as looking and steering in the direction you want to go, to ensure safe braking and control of the vehicle.
