Speed cameras in South Wales monitoring 20mph speed limit

Wales became one of the first countries in the world, and the first nation in the UK, to lower the default national speed limit on residential roads from 30mph to 20mph last September.

Enforcement on these roads has been paused since the new speed limit was rolled out allowing motorists a “grace period” to get used to the change.

GoSafe – a partnership made up of authorities including the Welsh Government and Wales emergency services – has been helping manage the 20mph change.

An “engagement first” approach was originally taken when it came to drivers caught over the speed limit in 20mph areas. 

But enforcement of the 20mph[1] speed limit on residential roads in Wales is now underway having started on March 18.

Full list of speed cameras in place to monitor new 20mph speed limit in South Wales

A list of “enforcement sites” has been revealed by GoSafe[2] where mobile and fixed speed cameras will be in place to ensure motorists are keeping to the new 20mph speed limit.

Our most successful cameras are those which capture 0 offences.

We want to make Welsh roads safer and 0 offences in a site means our enforcement is working.#GoSafehttps://t.co/PjDSMSnSMi pic.twitter.com/BJYuaOXo0f[3][4][5]

Sites where the 20mph speed limit will be enforced are based on where there has been evidence of road safety risk.

GoSafe considers enforcement where communities have raised concerns, collisions have occurred, or in areas where vulnerable road users and vehicles mix for example, near schools.
