Why 20mph?

Over 20 million people already live in local authorities in the UK which are adopting or have adopted this policy. This includes Wales where the First Minister has set up a Task Group to implement a 20mph national default for residential roads.

In February 2020, Global Ministers mandated 20mph or 30km/h speed limits 'wherever cyclists or pedestrians mix with motor vehicles with exceptions only where strong evidence exists that higher speeds are safe' (the Stockholm Declaration). This was also endorsed in August 2020 by the General Assembly of the United Nations. The World Health Organisation also endorses 20mph limits

A safe speed on roads with possible conflicts between cars and pedestrians, cyclists or other vulnerable road users is 30 km/h (20mph)"
