Question 4125
Which vehicles are required to have their clearance lights on when their use is mandatory?
- Those wider than 2.10 meters.
- Roadside assistance vehicles.
- Those transporting dangerous goods.
Show answer and explanation
Correct answer: Those wider than 2.10 meters.
If your vehicle is more than 2.10 meters wide, you must turn on the clearance lights along with the position lights whenever lighting is required. They indicate its overall width. Carrying dangerous goods or providing roadside assistance does not change this. In the image, the truck has its clearance lights on at the upper corners.
