What is the most appropriate translation for this law article? In this Skeptics answer, a user provided a rough translation of a Chinese law article — from this source — about vehicles and pedestrians using Google Translate. So I thought, why don't we provide a good translation?

The Chinese article is:


  第四十七条　机动车行经人行横道时，应当减速行驶；遇行人正在通过人行横道，应当停车让行。


And Google says:


  Article 47 of the motor vehicle when passing a crosswalk, shall slow down traffic; when a pedestrian is crossing a crosswalk, shall stop to give.


Not the best translation, certainly. What would be a more appropriate translation?
Article 47: When a motor vehicle vehicle passes through a crosswalk, it should proceed at reduced speed; in the case when a pedestrian is crossing the crosswalk, the vehicle should stop and yield to the pedestrian.
