Local road charges - which could include tolls and congestion charges - are included in the Welsh Government's strategy for transport in Wales. Officials think road charges could fund improvements in public transport and reduce the number of vehicles in the road.
The plans are one of the policies set out in the Welsh Government's National Transport Delivery Plan 2022 - 2027. Its ambition is to move more people away from using their cars by making public transport more effective and affordable, encourage people to walk or cycle as well as bringing services and facilities closer to where people live.
It said "fair road user charging" has the capacity to deliver that "modal shift" and says ministers in Wales have the power to give councils the right to bring in charges in their areas.
