What action must you take when a vehicle inspection reveals non-working brake lamps?

When a vehicle inspection reveals non-working brake lamps, the appropriate action is to record the significant defect and not operate the vehicle until the defect is repaired. Brake lamps are critical for safe driving, as they alert other drivers when the vehicle is slowing down or stopping. Operating a vehicle with non-working brake lamps poses a serious safety risk not only to the driver but also to others on the road, as it can lead to accidents due to a lack of communication between vehicles.

Addressing this issue ensures that the vehicle complies with safety regulations and is fit for operation. Immediate repairs are necessary to restore the functionality of the brake lamps, thereby maintaining safe driving conditions. Monitoring the vehicle’s condition or deeming the defect minor does not adequately address the potential dangers associated with faulty brake lights. It's important to prioritize safety above all else in these situations.
