Visibility is critical to safety. Drivers must have a good view of the road, signs and other road users. It is necessary to regularly top up the washer fluid, and do not forget to regularly clean all the windows in your car. Dirty side windows can make it difficult to use the mirrors, as well as prevent or delay notification of an approaching car from the side. When the driver sees only fragments of the road, he cannot quickly see hazards and react!
In addition, visibility is impaired by the sun's rays. When sunlight hits a dirty window at a certain angle, the driver may temporarily lose all visibility and ability to see the road.
As with keeping windows clean, you should also take care to clean your headlights. Dirt can reduce the range and intensity of the light emitted.
