How can you identify if your trailer is equipped with anti-lock brakes?

The presence of a yellow ABS light during a light check is the correct indication that your trailer is equipped with anti-lock brakes. This light serves as an important visual signal that alerts you to the status of the anti-lock braking system (ABS). If the yellow light illuminates, it confirms that the system is in place and functioning properly.

Understanding the significance of the ABS light is vital for safety on the road. ABS helps prevent the wheels from locking up during hard braking, which aids in maintaining steering control. It's essential for drivers to be familiar with this indicator, as it can influence braking performance, especially in slippery conditions.

In contrast, while a red ABS light might suggest an issue, it does not specifically indicate the presence of anti-lock brakes. Sound from the braking system wouldn't reliably identify the presence of ABS either, as different braking systems may produce various sounds. Inspecting the brake lines can help confirm the integrity of the braking system, but it doesn't provide information about the ABS feature itself.
