131. Weather
Weather can have a major effect on driving conditions by reducing visibility, grip and vehicle control. Rain, fog, snow, ice, strong wind and bright sunlight can all increase the risk of an accident. Drivers should adapt their speed and following distance to the conditions, avoid sudden steering or braking on slippery roads and use the appropriate lights when visibility is reduced. Even when driving below the posted speed limit, a driver may still be travelling too fast for the weather and road conditions.
