Question 1644 · Truck theory test

At night, what effect could driving with a single headlight have on oncoming drivers?

Pick an answer to test yourself.

Correct answer

They could mistake the vehicle for a motorcycle.

Official explanation

Motor vehicles, except motorcycles, are required by law to have two headlights. A vehicle with only one headlight could be mistaken for a motorcycle, and other road users could believe that it is in a different position on the road than it actually is. Vehicle lights should be checked on a regular basis, and faulty lighting should be repaired immediately.
