Driving on wet and slippery roads can cause a vehicle to lose traction and spin out of control. Vehicles equipped with an anti-lock braking system, will prevent the wheels from locking up and allow the driver to maintain control of the vehicle while concentrating on steering to safety. Drivers should keep their foot firmly placed on the brake pedal because the ABS braking system will automatically pump the brakes. The term ABS stands for anti-lock braking system. 

There are several types of anti-lock braking systems available as standard or optional equipment. The vehicle's owner's manual will indicate whether the vehicle is equipped with anti-lock brakes. When a vehicle is not equipped with an anti-lock braking system, drivers must manually pump the brakes to prevent wheels from locking up during a sudden stop. 

When a driver engages the anti-lock braking system, they may feel a slight vibration or hear a grinding noise. This is normal and indicates the anti-lock braking system is working properly. Maintaining control of the vehicle during sudden stops is enhanced with anti-lock braking systems. Drivers should use caution when driving in bad weather and lower their speed to adjust to the road conditions. 

During a sudden stop, a driver who is operating a vehicle without an anti-lock braking system, will need advanced driving skill to bring the vehicle to a safe stop. Tires should be regularly checked for correct tire pressure. The brake system needs regular maintenance by checking the brake fluid levels and regular changing of the brake fluid. Driver reaction time will also affect the overall distance required to bring the vehicle to a safe stop. Maintain a safe distance from other vehicles during bad weather because the safe stopping distance is increased. 

When a driver applies pressure to the brakes, the anti-lock controller uses information collected by sensors and controls the braking force to the wheels. This process repeats itself as long as the driver has pressure on the brake pedal. This will provide the vehicle's braking system to prevent the wheels from locking up. 

Driving a vehicle equipped with an anti-lock braking system won't make a vehicle stop faster. The anti-lock braking system's purpose is to help the driver maintain control of the vehicle by keeping the wheels from locking up. If the vehicle loses control and the wheels lock up, the driver will not be able to steer safely. Safe driving means being alert and aware of road conditions.
