Anti-lock Brakes (ABS)

One of the first things that drivers learn when learning how to become a driving instructor is how ABS systems work. They operate by rapidly pumping the brakes on and off several times per second (much faster than the best and quickest human) . This allows the driver to maintain directional control in an emergency. This is especially useful if you get into trouble on a slippery surface.

ABS is a standard requirement on modern cars but when it was first intoduced cars equipped with ABS attracted a lower insurance premium - however, insurance companies soon discovered that ABS did not lead to fewer claims, just different claims. ABS is a valuable safety addition to cars but will not compensate for bad driving!

For drivers who 'tailgate' ABS will be of little use. If your view from the drivers seat is usually like the picture on the right - drop back!

Your driving instructor probably told you about the two-second rule - if you keep a safe distance you can avoid the need for emergency braking.

The latest technologies go one step beyond ABS and intervene when a vehicle seems to be going off course. This is done by applying the brakes on individual wheels.

Points to bear in mind when using ABS

Read your vehicle manual:

Your owner's manual will explain how to use the ABS most efficiently in your particular vehicle.

Keep your foot on the brake:

With many systems that can be a noise (like a machine gun) and a pulsating of the brake pedal. The first time you experience this it can feel strange. Don't wait for an emergency, go out and test your ABS to get a feel for it (Note: Ensure that you do this in a safe location that is clear of other traffic and people).

Remember to steer:

This means looking where you want to go (your escape route). This might mean looking at the verge and driving off the road. If you stare at the danger, your arms won't work and you will still hit it.

The rule is 'Look at what you want to hit!' - the space, not the obstruction.

Always keep a safe distance ...

Leave sufficient (see the two-second-rule) space in which to stop. ABS is a great help but it won't stop you crashing. If you drive too fast or too close, expect to suffer the consequences.
