A controversial ban on vehicles entering the centre of a west Wales seaside resort has begun.
Cars will be banned from the narrow streets from 11am to 5pm
Cars and lorries are barred from entering or moving within Tenby's walled area between 11am and 5pm until the end of August.
Cameras similar to those used in London for the congestion charge will read the number plates of all vehicles entering the ban zone and will send the information to a computer database.
Those found to be breaking the rules face a £60 fine and three penalty points on their licence.
The scheme has divided opinion in Tenby but Pembrokeshire council says it will make the streets safer, end crippling traffic jams and encourage more tourists to visit the area.
After last year's pilot project the authority carried out a survey of more than 1,500 residents, with two-thirds of those who responded in favour of the ban.
But the Tenby Walled Town Residents Association has fought the ban saying the hours of operation and the size of the fine are excessive.
Association vice-chairman Alistair Mackay said: "Last year we had an experiment for four weeks for four hours a day but this is for eight weeks for six hours a day.
"It was a nice experience on the face of it with people walking around the town with no traffic but we feel it's gone too far this year."
He said businesses in the walled area relying on courier deliveries would be affected as they are not exempt and those whose homes fall within the boundary should be given some leeway.
Mr Mackay added: "We are not against solving Tenby's traffic problem but we think this should be more flexible."
The emergency services are exempt and a helpline has been set up for others seeking permission to enter the ban zone.
The scheme in Tenby will run from 5 July to 31 August
Pembrokeshire council's cabinet member for transport Brian Hall said: "The scheme goes ahead again this year, following positive feedback from residents businesses and visitors at the end of the experiment last year.
"The council hopes the initiative will improve the enjoyment of the town by residents and visitors alike and encourage more people to return to Tenby in the future.
"Tenby is an important tourist destination in the county and we recognise that in order for visitors and locals to enjoy the town in a traffic free environment, certain restrictions need to be placed on the residents and businesses situated within the walled town and on Caldey Island."
Two free park and ride bus services will run daily between 1000BST and 1800BST.
One will travel from the Salterns car park to South Parade every 15 minutes while the other runs from the North Beach car park to the harbour every 10 minutes.
The helpline number is 0845 6021386.
