Spain offers support to Wales with 20mph roll-out
The country introduced similar changes in 2019.
Wales' new 20mph speed limit is receiving international support with Spain's head of road safety saying the transition is easy to get used to and will soon feel 'normal'.
The country brought in a similar reduction in 2019 and has seen a drop in the number of deaths on the roads.
Álvaro Gómez is Head of the National Road Safety Observatory in Spain and played a key part when the country changed the speed limit on the majority of its roads to 30km/h.
Mr Gómez said: “The main target for us was to reduce the number of serious and fatal incidents in Spanish cities.
“Eight out of ten fatalities in cities are vulnerable road users and this includes pedestrians, cyclists, motorcyclists and e-scooter users.
“Speed is key to reducing risk. We have an older population in Spain and we were concerned about the number of pedestrians who were killed or seriously injured in road accidents.
“We didn’t have any serious incidents with local authorities over implementation. It all went well.
Spanish drivers and road users and cyclists and pedestrians are very comfortable with the new limit.
“The main message to people of Wales is that you can do it.
“There will be some fears beforehand but our experience and the experience of other cities across the world is that once it is done things become normal quickly.
“There are no big delays, there is no congestion there is no increase of pollution.
“Everything becomes normal, and everything gets better.”
The majority of residential roads across Wales now have a speed limit of 20 miles per hour but local authorities do have the power to make some roads exempt - keeping them at 30 miles per hour.
