ABS senses when a wheel is about to lock and adjusts brake pressure automatically, so you can keep steering while braking hard. It does not necessarily shorten stopping distance, and you should brake normally and let the system do its work.
If the ABS malfunction lamp comes on, there is no need to panic, because the regular brakes keep working as they always do. Keep driving and braking normally, and have the antilock system serviced as soon as you can.
When you brake hard on a slippery road, the wheels can lock and make the bus skid. ABS prevents the wheels from locking, which lets the driver keep control. It does not always shorten the stopping distance, and it cannot stop skids that come from turning too sharply.
Vehicles with ABS have a yellow lamp on the dash that lights to warn of a problem in the system. Normal braking still works without ABS, so keep driving carefully and have the system repaired soon.
ABS uses a computer to keep the wheels from locking during hard braking, which helps prevent skids and lets you keep steering. It does not, however, necessarily shorten the time or distance you need to stop.
By keeping the wheels from locking up under hard braking, ABS lets you keep steering and lowers the chance of a skid. Federal rules have required ABS on most new trucks, tractors and trailers since the late 1990s.
ABS keeps the wheels from locking and helps you stay in control when you brake hard, but it does not make up for speeding, tailgating, or careless driving. Keep the same following distance you always would; the system supports good habits but does not replace them.
ABS keeps the wheels from locking during hard braking, so you can keep steering, which helps most on slippery roads. It is required equipment on newer trucks, not an option.
ABS keeps the wheels from locking when you brake hard on a slippery surface, so there is no need to pump the brakes. Your usual braking habits do not change: press only as hard as it takes to stop safely while keeping control.
Your ordinary brakes keep working when ABS fails on some wheels, so there is no need to stop; simply drive as you normally would. Have the antilock system checked and repaired at the earliest chance.
Every bus with ABS has a yellow ABS malfunction light on its dashboard, and on newer buses it comes on briefly at start-up as a bulb check. ABS has been required on air-brake buses built since March 1, 1998, and on hydraulic-brake buses built since March 1, 1999.
Trucks, tractors, and buses equipped with antilock brakes have a yellow ABS warning lamp on the dash. On newer vehicles it comes on briefly at startup as a bulb check and then goes out.
ABS does its job automatically, so brake the way you normally would and use only as much pressure as the stop calls for. Pumping the pedal interferes with the system, and ABS does not necessarily shorten your stopping distance.
ABS senses when a wheel is about to lock during sudden, hard braking and adjusts brake pressure so the wheels keep turning and the vehicle does not skid. It will not necessarily shorten the stop, and it does nothing to prevent a skid caused by turning too sharply.
