You are driving and both the low air buzzer and warning light activate at the same time. What does this most likely mean compared to just one activating?
Pick an answer
Correct!
Not quite. The correct answer is highlighted.
Correct answer to question 22 (Air Brakes): That the vehicle has two separate warning systems both confirming the same low pressure condition, and the situation should be treated seriously either way
Why
Whether one or both warnings activate, the underlying message is the same: air pressure has dropped below the safe threshold, and the driver needs to stop and address it rather than waiting to see if it gets worse.
