What indicates that a vehicle should not overtake?

A continuous line on the road is an important visual signal that indicates vehicles are prohibited from overtaking in that area. This marking typically appears in situations where it is unsafe to pass, such as near curves, intersections, or areas with limited visibility. The presence of the continuous line serves as a clear warning to drivers, helping to prevent accidents by maintaining safe distances between vehicles.

In contrast, while a "STOP" sign and a red light also indicate that a vehicle must stop, they do not specifically communicate anything about overtaking. A "NON-STOP" box may suggest that vehicles should not stop in that area, but it does not directly relate to the action of overtaking. Understanding these roadway markings helps ensure safer driving practices and compliance with traffic regulations.
