What is not a reason to use dim-bright headlights at night?

Using dim-bright headlights at night is essential for the safety of all road users. Each situation where dim headlights are recommended aims to reduce glare and improve visibility for both the driver and others on the road.

When considering the correct answer about when not to use dim-bright headlights, it's important to point out that driving when no other vehicles are present does not necessitate the use of dim headlights. In an empty road environment, drivers can generally use their bright headlights, assuming there are no other road users to affect. This allows for maximum visibility without the risk of blinding others.

On the other hand, in scenarios involving oncoming traffic, well-lit roads, or closely following another vehicle, dim headlights are essential. When traffic approaches from the front, bright headlights could blind the oncoming driver, leading to dangerous situations. Similarly, driving on a well-lit road typically does not require bright headlights, as sufficient street lighting provides the necessary visibility. Lastly, when following another vehicle closely, using bright headlights can blind the driver in front, so dim headlights are preferred to maintain safe distances and visibility without causing hazard.
