夜間應選擇能及時停車的車速：劃分車道的道路須能在前方看得清且無障礙的道路距離內停車；未劃分車道時，須能在該距離的一半內停車。

If visibility or grip is reduced, slow further as needed. The posted maximum does not guarantee a safe speed. This is a stopping-distance rule, not the two-second following-gap rule.
能見度或輪胎抓地力降低時，應按需要進一步減速。標示最高限速不代表當時一定安全。這是停車距離要求，不是判斷跟車間隔的兩秒規則。
