When is it appropriate to use high beams while driving?

Using high beams while driving is appropriate when it is safe and legal to do so. High beams enhance visibility by illuminating the road further ahead, which is particularly useful in rural or dark areas without street lighting. However, high beams should not be used when other vehicles are approaching, as they can blind other drivers and create hazardous conditions. It is essential to know when it is safe to switch to high beams, such as when you are driving without oncoming traffic or following another vehicle, ensuring that your use of high beams does not compromise the safety of others on the road.

The other options suggest scenarios where it may not be suitable to use high beams, such as during heavy traffic, in bad weather, or at all times, where their use may cause visibility issues for yourself and others.
