In what situations is overtaking not allowed?

[OOwen]

When the vehicle ahead is making a left turn, U-turn, or overtaking; when there is a possibility of encountering oncoming vehicles; when the vehicle ahead is a police car, fire truck, ambulance, or engineering rescue vehicle performing emergency tasks; when passing through railway crossings, intersections, narrow bridges, curves, steep slopes, tunnels, pedestrian crossings, or urban sections with heavy traffic, where overtaking conditions are not met. Do not overtake when visibility is poor due to wind, rain, snow, fog, or excessive dust raised by the vehicle ahead; generally, overtaking is not allowed when there is an oncoming vehicle within 150 meters ahead, and it is best to operate the vehicle within a 200-meter range; do not overtake when visibility is obstructed, such as when turning or crossing the top of a slope; double overtaking is not allowed when the vehicle ahead is overtaking; do not overtake when passing through Huaying Street, tunnels, narrow bridges, railway crossings, school gates, icy roads, or when towing a damaged vehicle. Do not overtake at intersections, such as when a car is driving on the main road. Do not overtake when there is a branch road on the left side to prevent accidents caused by the overtaken vehicle suddenly turning left.
