Sunstrike can happen at any time during the day, but most likely during sunrise or sunset, when the sun’s rays hit your windscreen at a low angle. This can make it difficult, or even impossible, to see. This is a very dangerous condition to drive in. Follow these guidelines to avoid a crash.

Reducing the danger of sunstrike

  • Be prepared for possible sunstrike when driving at sunrise or sunset, especially when turning or driving towards the sun. 
  • Be especially careful in winter, when sunstrike is more likely, because the sun is lower in the sky. 
  • Keep your windscreen clean, inside and out. Dust and grime on the windscreen can make the effects of sunstrike much worse. 
  • Wear sunglasses when driving with the sun in your eyes. 
  • Use your car’s sun visors to block the sun. 
  • If you experience sunstrike, it may be safest to pull over and wait for a few minutes until your eyes adjust or visibility improves. 
  • Be careful if snow has fallen and the sky is clear – sunlight shining on snow can cause snow blindness, which produces similar effects to sunstrike.
