Which of the following is NOT a condition for using high beam lights?

Using high beam headlights is appropriate under certain conditions to enhance visibility while driving, particularly in low-light situations. However, it is essential to ensure that they are not used when they can blind other drivers or create unsafe conditions.

The correct response points out that using high beams while passing slow vehicles is not a suitable condition. When approaching or passing another vehicle, especially if that vehicle is in close proximity or oncoming, using high beams can significantly impair the other driver's vision. Instead, it is better to switch to low beams to maintain safety for both drivers.

In contrast, the other conditions for using high beams, such as driving on highways without street lighting, where visibility is limited, are appropriate as they help illuminate the road ahead. Similarly, using high beams in open areas where the view is obstructed or limited enhances the driver's ability to see obstacles. However, intersecting roads without traffic lights requires caution since high beams might dazzle other road users as well, but they could still be used in certain scenarios where it’s safe to do so.
