Manitoba Airbrake Practice Exam

When a malfunction occurs in the anti-lock braking system, a warning light typically illuminates on the dashboard. This indicates that there is an issue with the system and it should be checked by a mechanic. Option B, a warning sound, is incorrect because most vehicles do not have an audible warning for an anti-lock braking system malfunction. Option C, the vehicle pulling to one side, may indicate a problem with the brakes, but it is not specific to the anti-lock braking system. Option D, none of the above, is incorrect because the warning light is the most common and reliable indicator of a malfunction in the anti-lock braking system.
