Which of the following types of vehicles must have a low rear collision protection bumper?
- Commercial vehicles with a rear extension that covers 60% of the axle distance.
- Commercial vehicles, trailers and semi-trailers with an all up weight of 3,500 kg or less.
- Connected vehicles, integral commercial vehicles and semi-trailer trucks with an all up weight of more than 15,000 kg.
- Correct answer: Commercial vehicles, trailers and semi-trailers, and work vehicles with an all up weight of more than 3,500 kg.
Why this is the answer
The correct answer in the official bank: Commercial vehicles, trailers and semi-trailers, and work vehicles with an all up weight of more than 3,500 kg.
A low rear collision protection bumper stops a small car that hits from behind from sliding under the high chassis of a heavy vehicle. That is why it is required on commercial vehicles, trailers, semi-trailers and work vehicles with an all up weight of more than 3,500 kg. Lighter vehicles are usually low enough, and limiting the rule to vehicles over 15,000 kg is too narrow.
