When the rear wheels are off the ground, what is the status of the rear wheel parking brakes?

• A. Not Available
• B. Fully Engaged
• C. Automatically Engaged
• D. Not Applicable

Answer: (A)

When the rear wheels are off the ground, you can’t determine or observe the parking brake’s true state because there’s no ground contact to create braking resistance or to verify that the mechanism is holding. In this situation, the status is not meaningful or usable, which is why the appropriate choice is Not Available. If the vehicle were on the ground, you could test whether the parking brakes hold the weight, but with the wheels raised, you can’t confirm engagement or release. The other options imply a definite active state or automatic behavior, which isn’t applicable when the wheels aren’t bearing weight.
