What color is the malfunction lamp for anti-lock brakes on a dolly?

Red Yellow Green Blue

Correct Answer:

Yellow

Explanation:

The malfunction lamp for anti-lock brakes (ABS) on a dolly is yellow. This color is used to indicate a caution or warning condition. When the ABS light is illuminated, it typically signifies that there is a fault in the ABS system. The yellow color helps drivers quickly recognize that there may be a problem that requires attention, while not indicating an immediate emergency, as would be the case with a red light. Understanding the color coding of warning lights is crucial for ensuring the safety and functionality of the braking system, allowing drivers to take necessary actions to maintain vehicle safety.
