Head lights which are not properly adjusted:
- Make the driver more alert.
- Cause self-blinding of the driver.
- Have no effect on driving and on vehicle control.
- Correct answer: Do not illuminate the road properly.
Why this is the answer
The correct answer in the official bank: Do not illuminate the road properly.
Headlights that are not properly adjusted do not illuminate the road as required. If they are aimed too low, the visibility range is shortened. If they are aimed too high, they dazzle oncoming drivers. It is therefore important to check the headlight adjustment from time to time, especially after a repair or when the vehicle carries a heavy load.
