Which of the following vehicles must be equipped with a reverse-drive buzzer?
- All commercial vehicles must be equipped with this buzzer.
- Vehicles with an all up weight of 12,000 kg or less.
- Vehicles with an all up weight of more than 4,000 kg.
- Correct answer: Commercial vehicles and work vehicles with an all up weight of more than 15,000 kg, tractors and buses.
Why this is the answer
The correct answer in the official bank: Commercial vehicles and work vehicles with an all up weight of more than 15,000 kg, tractors and buses.
A reverse buzzer beeps while the vehicle backs up, warning pedestrians and drivers behind it. The duty applies to large vehicles where the driver's view to the rear is especially limited: commercial and work vehicles with an all up weight of more than 15,000 kg, plus tractors and buses. Not every commercial vehicle needs one, and the rule is not based on a 4,000 kg limit.
