If a tractor, truck, or bus has anti-lock brakes and the yellow ABS malfunction lamp lights up on the instrument panel when you are underway, you should know?

When the yellow ABS malfunction lamp illuminates on the instrument panel while the vehicle is in motion, it indicates that the Anti-lock Braking System (ABS) may not be functioning properly. The ABS is designed to prevent wheel lock-up during hard braking, thereby maintaining vehicle control. If the warning light is on, it serves as a crucial alert that the safety feature intended to help in slippery conditions or during emergency stops is potentially compromised.

A malfunctioning ABS means that the vehicle may not only take longer to stop but also that you may lose traction and control in critical braking situations. Therefore, it is essential to address this warning immediately by seeking vehicle inspection and repair, as continued operation of a vehicle with a disabled ABS can pose significant safety risks. Knowing this helps drivers understand the importance of responding to dashboard indicators promptly to ensure their safety and that of others on the road.
