The sign "Overtaking ban for motor vehicles over 3.5 t" indicates that motor vehicles with a weight exceeding 3.5 tons are prohibited from overtaking in that area. This restriction is typically placed in zones where safety is paramount, such as curves, intersections, or areas with heavy traffic, ensuring smoother traffic flow and reducing the risk of accidents. Drivers of vehicles exceeding this weight must adhere to this regulation and cannot overtake lighter vehicles in that section of the road. Always observe such signs closely to ensure compliance with traffic laws and maintain safety on the roads.
