A SPEED limit could be axed for millions of drivers next week amid pressure to scrap controversial 20mph zones in residential areas.
Wales could see the national speed limit increased as Welsh Conservatives call for a more “targeted approach”.
But the restriction could remain in place in certain areas.
Shadow Transport Minister Natasha Asghar MS said: "Labour Ministers in Cardiff Bay continue to push their anti-motorist agenda, with drivers being forced out of their vehicles through Labour Government policy."
“The people of Wales want to get on with their daily lives, yet Labour’s lack of investment in public transport, road building ban, and 20mph speed limits are preventing them from doing exactly this.
"In the Senedd next week, we’ll be calling on the Welsh Labour Government to end their war on motorists, scrap their road building ban and 20mph speed limits, and to get Wales moving again.”

Transport minister, Lee Waters, did not rule out changes to the policy should it fail to achieve the expected outcomes.
However, he said: "So far it is going as we anticipated - speeds are down, and just as everywhere else that has introduced lower speeds, we expect that to result in fewer collisions, deaths and casualties.”
A Welsh Government spokesperson said: “The Cabinet Secretary has been clear that his immediate priority on 20mph is to listen.
"To support this, in the weeks ahead he will be engaging with elected representatives, businesses and communities across Wales.”
