What do you mean there are bicycles and arrows on the traffic signs?

There are bicycles and an arrow on the traffic sign, indicating non-motor vehicle lanes.

Non-motor vehicle lanes are usually white bicycle signs with a blue background. They will be set at the starting point of roads or lanes and the entrance of intersections to remind people that there are non-motor vehicle lanes ahead. If there are non-motor vehicle lanes, non-motor vehicles should drive in non-motor vehicle lanes as required. If not, they should drive on the right side of the driveway.

Non-motor vehicle lanes refer to the lanes on expressways and urban roads from the right sidewalk tooth (line) to the first motor vehicle lane (or isolation belt, pier) or drawn on the sidewalk, except in special circumstances, which are exclusively used by non-motor vehicles.

Non-motor vehicle lanes are mainly roads for bicycles, flatbeds, tricycles, electric vehicles and animal-drawn vehicles. At present, there are a large number of non-motor vehicles running on various urban roads in China, among which bicycles and electric vehicles are the most prominent, and the number of bicycles and electric vehicles in most small and medium-sized cities is still increasing. Therefore, non-motor vehicles still occupy an important position in the city, and sufficient attention must be paid to the design of non-motor vehicles.

According to Article 36 of the Road Traffic Safety Law of the People's Republic of China, roads are divided into motor vehicle lanes, non-motor vehicle lanes and sidewalks according to road conditions and traffic needs, and motor vehicles, non-motor vehicles and pedestrians are allowed to pass in separate lanes. There are no motor vehicle lanes, non-motor vehicle lanes and sidewalks. Motor vehicles pass in the middle of the road, and non-motor vehicles and pedestrians pass on both sides of the road.
