Visitors to Chorley town centre can now park free every Saturday afternoon.
The new charging policy is part of a trial that will run until the end of February to see what impact it has.
It is the first time free parking has been offered in the town centre on a Saturday afternoon.
The new charges will see a complete shake-up of tariffs on both the long and short stay car parks.
It will also see a reduction in price in the one-hour parking option and the limit of three hours parking on short stay car parks increased to four hours in response to people saying they wanted to stay for longer in the town.
There are also changes to Farrington Street car park, which is now a long stay car park and Portland Street car park, which has been converted to short stay to encourage more people to use it if the nearby Flat Iron car park is full.
Councillor Alistair Bradley, leader of Chorley Council, said: “We are determined to make things happen to improve the local economy and the introduction of new parking tariffs is just one of a number of things we will be trialling to get more people into Chorley.
“We’ve listened to traders and shoppers when devising the new tariffs and they have been well received since we made the announcement about the changes last month.”
He added: “This is a trial so we will review the outcomes at the beginning of next year and may look to make further changes in the future to help shoppers and traders.”
