Question 1371 in the bank

It is obligatory to fit Extremity (width) side lights:

  1. Correct answer: On a 210cm-or-more wide vehicle.
  2. Only on connected vehicles or semi-trailers.
  3. On all commercial vehicles.
  4. On vehicles with an all up width of 180cm or less.

Why this is the answer

The correct answer in the official bank: On a 210cm-or-more wide vehicle.

Extremity (width) lights mark the outer edges of a wide vehicle, so other drivers can judge its width at night or in poor visibility. That is why they are obligatory on any vehicle 210 cm wide or more. The duty depends on the vehicle's width, not on whether it is a commercial vehicle or a connected vehicle, and narrow vehicles do not need them.
