When should high beams be used?

Using high beams is appropriate when it is safe and legal to do so, as they provide better visibility in low-light conditions, such as on dark country roads or during nighttime driving when there are no oncoming vehicles. High beams increase the distance you can see ahead, allowing you to spot hazards sooner and respond accordingly.

It's essential to consider the traffic around you; high beams should not be used when there is oncoming traffic or when you are following another vehicle closely, as they can blind other drivers. This practice not only enhances safety for you but also for others on the road. Understanding when it is appropriate to use high beams can significantly improve driving conditions and safety in various situations.

The other options suggest limited or inappropriate uses of high beams, such as using them only on empty highways or requiring their use at all times in the city. However, city streets often have street lighting, making high beams unnecessary and potentially dangerous for others.
