Basic speed law in rain｜雨天基本速度法则

原创练习题 / Practice question

The posted limit is unsafe in current heavy rain. What should you do?

限速牌允许的速度在当前大雨路况下不安全，应怎样做？

1. Exceed the limit with hazard lights on / 开启双闪后可超过限速
2. Reduce to a speed safe for the conditions / 降低到适合当前路况的安全速度
3. Match the fastest vehicle / 跟上最快车辆
4. Keep that speed as long as it is posted / 只要不超标志就继续原速

答案与解析 / Answer and explanation

Reduce to a speed safe for the conditions. The Basic Speed Law requires a speed safe for current conditions, even when that is below the posted limit.

降低到适合当前路况的安全速度。基本车速法要求车速始终适合当前路况，标示限速不能保证恶劣天气下同样安全。
