As shown in Brake’s recent research on 20mph limits, reducing limits from 30 to 20mph has been shown to reduce casualties because drivers have more time to react to unexpected events and emergencies. Children also benefit from slower speed limits because they struggle to judge the speed of vehicles over 20mph, so often make mistakes crossing roads with faster traffic.

A 2014 Brake survey found that eight in 10 people (78%) think 20mph should be the norm around schools, on residential streets, and in village, town and city centres.

The ‘GO 20’ resource challenges users to test their understanding of 20mph limits, and can be used to raise public awareness and encourage local authorities to introduce 20mph limits in their areas.
