Where should you not use your high beam headlights?

Using high beam headlights is not appropriate in fog, rain, or when approaching oncoming traffic because these conditions can significantly reduce visibility. High beams are designed to illuminate the road far ahead, but they can create a glare when reflected off precipitation or fog, making it even harder to see. This glare can rebound back into the driver’s eyes and adversely affect visibility.

Moreover, when approaching oncoming vehicles, high beams can cause temporary blindness for the other driver, creating a dangerous situation on the road. Instead of high beams, using low beam headlights in these situations is recommended because they provide sufficient illumination without creating glare for yourself or others.

In contrast, other environments mentioned, such as city streets, open highways, and parking lots, generally allow for the practical use of high beam headlights when there is no oncoming traffic or no immediate obstacles. However, caution should always be exercised regarding surrounding vehicles and pedestrians in these areas.
