There is overwhelming public support for a maximum speed limit of 20mph to be the norm around schools, on residential streets, and in village, town and city centres, a survey suggests.

The research, commissioned by road safety charity Brake and Allianz Insurance, shows eight in 10 people (78%) back a 20mph maximum limit and comes as Brake takes its Go 20 campaign to Parliament.

The Brake and Allianz Insurance survey also found:

• Seven in 10 (72%) say roads in their town or village need to be made safer for walking and cycling

• Eight in 10 (81%) say traffic travels too fast on some (51%) or most (30%) of their local roads

• Eight in 10 (79%) think it would encourage more people to walk or cycle if roads and routes in their town or village were made safer

Speakers at the Brake and Allianz Insurance Go 20 Parliamentary reception today (April 2) will discuss the benefits of 20mph limits and progress being made by local authorities in implementing them.

Areas that have already introduced 20mph limits have seen significant reductions in casualties, such as Portsmouth where they fell by 22%, and Camden, where crashes reduced by 54%.

Other high profile local authorities now implementing 20mph limits include the City of London, Birmingham, Newcastle and Edinburgh.

Julie Townsend, deputy chief executive, Brake, said: "With many people already reaping the benefits of living in 20mph areas, we're reaching a point where it makes no sense to retain 30mph as the default limit in built-up areas. It's time for the government to Go 20 nationally.”
