When should you use your high beams while driving?

Using high beams is appropriate when driving in conditions where visibility is reduced, and it is safe to do so, specifically when there are no oncoming vehicles. High beams illuminate the road further ahead, providing better visibility for the driver, which is particularly beneficial in rural or dark areas without streetlights.

Engaging high beams when there are no oncoming vehicles ensures that you can see as much of the road ahead as possible without risking blinding other drivers. In contrast, high beams can be dangerous if other vehicles are present, as they can impair the vision of other drivers. This is why they're discouraged in congested city traffic, where frequent stopping and starting occurs, and during the daytime when visibility is not an issue.

It's also not advisable to switch to high beams solely for changing lanes, as this maneuver is typically performed with normal headlights, ensuring the other vehicles around you maintain their visibility without disruption.
