When a heavy goods service vehicle is parked on a road at night, from what distance must its rear red light nearest the centre of the road be visible?

This is a specific parked-vehicle lighting requirement. Do not substitute the visibility distance for ordinary driving tail lights or projecting-load warning lamps. The parking position must also be legal and safe.

本题针对夜间停车灯光，不应混用其他行驶尾灯或超出货物警示灯的可见距离要求。仍须选择合法安全停车位置。
