When is it permissible to use high beams?

• A. In foggy conditions
• B. On open highways without oncoming traffic
• C. In well-lit urban areas
• D. During sunrise and sunset

Answer: (B)

Using high beams is permissible on open highways without oncoming traffic because high beams provide better visibility in darker conditions. This is especially useful on rural roads or highways where there are fewer artificial lights, allowing drivers to see further ahead and spot potential hazards. In this context, using high beams helps illuminate the road and surrounding areas more effectively, as there are no opposing vehicles to blind. This enhances the driver's ability to react to any obstacles or changes in the driving environment, contributing to overall road safety. In contrast, using high beams in foggy conditions can scatter the light, making visibility worse instead of better. In well-lit urban areas, streetlights provide adequate illumination, so high beams are not necessary and can potentially blind other drivers. Similarly, during sunrise and sunset, the angle of the sun can create glare, making high beams inappropriate as they may disrupt both visibility and the comfort of other drivers on the road.
