157. Sunlight

Sunlight can reduce visibility when the sun is low in the sky or when bright light reflects from wet roads, snow, buildings or other vehicles. Sun glare can make traffic lights, signs, pedestrians and other road users difficult to see. Drivers should reduce speed when necessary, keep the windscreen clean, use the sun visor or suitable sunglasses and leave extra space to react to hazards that may be temporarily hidden by glare.

Why can sunlight be dangerous when driving?

Bright or low sunlight can cause glare and temporarily reduce visibility, making traffic lights, signs, pedestrians and other road users more difficult to see.

When is sun glare most likely to cause problems?

Glare is often strongest when the sun is low in the sky, particularly around sunrise and sunset, and when sunlight reflects from wet roads, snow, glass or other bright surfaces.

What should you do when sunlight makes it difficult to see?

Reduce speed and increase your following distance so you have more time to react. Use the sun visor where helpful and avoid continuing at a speed that is too high for the available visibility.

Can a dirty windscreen make sun glare worse?

Yes. Dirt, grease, dust and streaks on the glass can scatter bright sunlight and make glare much worse. Keep the windscreen clean inside and outside.

Can sunglasses help while driving in bright sunlight?

Suitable sunglasses can reduce glare and improve visual comfort in bright conditions. They should not be so dark that they significantly reduce visibility, especially when entering tunnels or shaded areas.

Does a sun visor improve visibility?

Yes. A correctly positioned sun visor can block direct sunlight without unnecessarily obstructing the driver’s view of the road.
