More than 10,500 requests have been received by Welsh councils from residents to reassess roads that saw their limit lowered when the policy was introduced in September last year.
Police point to a drop in road causalities and crashes to suggest Wales’ flagship policy is working, although a recent poll said seven in 10 people still oppose the new limit.
One motoring organisation has said traffic calming measures like speed bumps should be installed to force drivers to do 20mph.
Welsh ministers said a 20mph limit would reduce deaths and noise and encourage people to walk or cycle when it was implemented in September 2023 - but it caused controversy with some drivers.
The limit changed on about 35% of Welsh roads - about 22,000 miles (35,171 km) in total - last year where lamp-posts are no more than 200 yards (183m) apart.

Statistics show a drop in casualties on 20mph and 30mph roads in Wales in the first three months of 2024, after the default built-up area limit was reduced.The number of serious casualties or fatalities has dropped 23%, and Wales’ largest police force says there have been at least 11 less deaths on the roads in their area.
This is sadly quite common, and I think by design in many places.
Rather than long, open roads having a 30mph speed and smaller residential roads at 20, the opposite is chosen, purely because councils know that they can put speed cameras there to make some money. Making roads safer through design costs money, and many roads where accidents are common are largely ignored.
It’s these tactics that feed into the hysteria that these measures are an attack on motorists. While I largely agree with the rules, many councils really take the piss. I was caught doing 24mph in a 20, but was able to overturn it because the camera was placed in the middle of a hill with a sharp enough decline to not make it legal to police.
They probably made a ton from that camera, all while the top of the hill is a small junction where people regularly crash - which is 30 and is only repaired when someone crashes into the traffic lights (not a rare occurrence).
