When can you legally use your high beams?

Using high beams is permitted under specific conditions to enhance visibility without blinding other drivers. The correct choice is that high beams can be used only when there is no oncoming traffic. This is important because high beams illuminate a greater area ahead and can significantly improve visibility in dark conditions; however, they can also dazzle approaching drivers, potentially leading to dangerous situations.

When driving at night, high beams should be dimmed to low beams when another vehicle approaches within 500 feet or when following another vehicle within 350 feet. This ensures that other drivers are not impaired by excessive glare.

While high beams can enhance driving visibility significantly, they are not recommended for use in city driving, where streetlights provide adequate illumination, nor are they suitable during the daytime when regular headlights are sufficient. Therefore, it's crucial to be mindful of when to activate high beams to maintain safety for all road users.
