Parking is allowed on roadsides where parking lines are marked. Below are specific details on where parking is prohibited: Sections with no-parking signs or markings: Parking is not allowed on sections with isolation facilities between motor vehicle lanes, non-motor vehicle lanes, and sidewalks, as well as at pedestrian crossings and construction areas. Intersections: Parking is prohibited at intersections, railway crossings, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, and within 50 meters of these locations. Additionally, parking is not allowed in front of bus stops, emergency stations, gas stations, fire hydrants, or fire stations, and within 30 meters of these locations, except when using these facilities.
