Which indicator confirms that you are driving with anti-lock brakes?

The yellow ABS malfunction lamp on the instrument panel illuminating when you start the engine is an important indicator of the presence of anti-lock braking systems (ABS) in a vehicle. When the engine is turned on, this lamp typically lights up temporarily as part of the self-check process for the vehicle's systems, including ABS. If the system is functioning correctly, the light will turn off after a few moments. Such systems are designed to prevent wheel lock-up during braking, helping maintain steering control.

In this context, the presence of the yellow ABS warning light serves as an initial confirmation that the vehicle is equipped with anti-lock brakes and indicates that the system is operational unless the light stays on, which would suggest a malfunction. This is critical for drivers as it ensures they are aware of their braking capabilities, especially under emergency braking situations.

Other options such as the red indicator lamp or the green light are not standard indicators of ABS function. A red indicator typically signifies a serious issue that requires immediate attention, while a green light usually signals an active system but is not commonly associated with anti-lock brakes. The option indicating no indicator fails to consider the importance of dashboard alerts in modern vehicles for driver awareness.
