Antilock Braking Systems - Commercial Driver's License (General Knowledge)

The main indicator that your vehicle is equipped with an ABS is the yellow malfunction light in your instrument panel. If your vehicle is to code, and it was produced after March 1998 it should be equipped with an ABS. Also, you can always just physically get out of the cab and look at the back of your brakes for the telltale presence of wheel speed sensor wires. Your speedometer indicating both miles and kilometers per hour is not related to your ABS (it may mean your truck was manufactured in Canada).

The only purpose listed that is true of ABS is that they are designed to prevent a vehicles brakes from locking. Obviously this is more important for large or heavy vehicles, whose brakes lock more easily than other vehicles, and which pose a much greater threat when moving across a road with locked brakes.
