What is the meaning of an unbroken white line in the middle of the road?

Answer: B — You must not overtake there

An unbroken white line in the middle of the road indicates that drivers are not permitted to overtake vehicles in that particular area. The purpose of this marking is to enhance road safety by preventing overtaking where visibility may be limited or where it could create dangerous situations. Typically, these lines are used in areas like curves, intersections, or places with high pedestrian activity, where overtaking would pose a significant risk. The significance of this marking should be taken seriously as ignoring it can lead to accidents or violations of traffic regulations. Understanding such road markings helps ensure a safe driving environment for everyone on the road.
