Which types of urban roads prohibit overtaking when driving a motor vehicle?

[Karl]

The "Road Traffic Safety Law of the People's Republic of China" stipulates: Article 43: When motor vehicles are driving in the same lane, the following vehicle must maintain a safe distance from the vehicle ahead to allow for emergency braking measures. Overtaking is prohibited under the following circumstances: 1. When the vehicle ahead is making a left turn, performing a U-turn, or overtaking another vehicle. 2. When there is a possibility of encountering oncoming traffic. 3. When the vehicle ahead is an emergency vehicle such as a police car, fire truck, ambulance, or engineering rescue vehicle performing urgent duties—overtaking is not allowed, and the driver must yield to ensure its emergency passage. 4. When passing through areas where overtaking is unsafe, such as railway crossings, intersections, narrow bridges, curves, steep slopes, tunnels, pedestrian crosswalks, or sections of urban roads with heavy traffic flow.
