When is it safe to use your high beams?

Using high beams is safe on dark roads when there are no oncoming vehicles or when driving alone because they provide increased visibility to illuminate the road further ahead, which is particularly useful in low-light conditions. High beams are designed to cast a wider and stronger light beam that can help drivers see obstacles, animals, or other hazards that may not be visible with standard headlights.

In contrast, using high beams in foggy conditions can create glare that reflects back into the driver’s eyes, reducing visibility rather than improving it. During heavy traffic, high beams can blind other drivers and create dangerous driving conditions, while well-lit city streets typically provide enough illumination for safe driving without the need for high beams. Hence, using high beams is only advisable in specific situations where it will not negatively affect other road users.
