Difficulty: MediumBasic Maintenance and Daily Checks

Before setting off on a journey, you need to check that all your rear brake lights are working properly, but you are alone and have no one to help you. How should you safely carry out this check?

  1. A
    Rely on the dashboard charging warning lamp to alert you if an exterior bulb has failed.
  2. Reverse towards a wall or garage door and look for the red reflection in your mirrors.Answer
  3. C
    Ensure the tyre tread depth is above 1.6 mm across the central three-quarters before assuming the lighting circuit is intact.
  4. D
    Increase all tyre pressures to the heavy-load setting so the automated lighting diagnostic system activates.

Answer

Reverse towards a wall or garage door and look for the red reflection in your mirrors.
When checking brake lights without an assistant, reversing close to a reflective surface—such as a garage door, flat wall, or window—enables the driver to press the brake pedal and confirm in their rear-view and side mirrors that the bright red brake lights illuminate.

Step-by-Step Solution

1
Position the vehicle with the rear facing a reflective surface such as a garage door, wall, or window.
The rear lighting units are oriented towards a surface that will reflect light back towards the driver.
This allows the light beam to bounce back into the driver's line of sight.
2
Press the footbrake while observing the interior rear-view mirror and external side mirrors.
The bright red reflection of the brake lamps becomes clearly visible on the surface behind.
This confirms that all rear brake light bulbs illuminate upon pedal application without requiring an assistant to stand outside.
