Where is the ABS indicator lamp located on a converter dolly with ABS?

• A. On the dashboard center.
• B. A yellow lamp on the left side.
• C. On the steering column.
• D. There is no lamp.

Answer: (B)

Anti-lock braking system indicators warn you if the system on the trailer or dolly isn’t functioning. For a converter dolly with ABS, the indicator lamp is a yellow light mounted on the left side of the dolly. This placement keeps the status visible to the driver without needing to glance at the tractor’s controls, and it distinguishes the dolly’s ABS status from the tractor’s dash lights. The center of the dashboard or the steering column are not where the dolly’s ABS status is shown, and there is indeed a lamp on the dolly, so those options don’t fit. If the lamp lights up or stays on, it signals a fault in the dolly’s ABS that should be checked.
