What is “perimeter lighting” according to traffic regulations?
- Correct answer: A yellow lighting system arranged around an oversize freight. The distance between lamps should not exceed 100 cm.
- Green lights installed on the sides of long vehicles.
- A portable lighting system that has a chain on which flags are installed. The minimum distance between the flags should be 50 cm.
- A fixed lighting system on the walls of long vehicles.
Why this is the answer
The correct answer in the official bank: A yellow lighting system arranged around an oversize freight. The distance between lamps should not exceed 100 cm.
Perimeter lighting marks the outline of an oversize freight so other drivers can see its size and shape, especially in the dark. It consists of yellow lamps arranged around the load, spaced no more than 100 cm apart. It is not green side lights or a fixed lighting system on the walls of a long vehicle, and a chain with flags is not lighting at all.
