What does the double white line mean?

The presence of a double white line signifies that crossing is prohibited for all vehicles. This marking is designed to enhance road safety by preventing drivers from overtaking or changing lanes in areas where it may be dangerous to do so. Such areas often include locations with restricted visibility, like curves or intersections, where the risk of collisions is heightened. This clear regulation helps maintain order on the road and ensures that vehicles stay in their designated lanes to avoid accidents. It's important for drivers to recognize and obey this road marking to promote safety for themselves and other road users.
