The parents of a wheelchair-bound teenager have criticised the "inconsiderate" motorists who block their daughter's route into Chorley.
Laura May, 16, from Kirkstall Road, Chorley, was left paralysed after a back operation in 2005, the subject of an ongoing legal battle.
However, her parents Bill and Christine May say the challenges facing their daughter are being made worse by selfish motorists.
On Saturday she was forced to take a detour after her access from the Fleet Street car park to Whalley Street was blocked by cars.
Her parents hope the picture will shame drivers to think twice.
They said: "We had an appointment in the town centre on Saturday morning and we couldn't get on the Flat Iron car park because the sign was showing that it was full.
"We use Fleet Street car park quite a lot and it wasn't the first time that it was blocked. It is very frustrating, especially when you have an appointment as it takes time to have to turn back and walk around.
"There was no way that we could get through, it is so inconsiderate.
"The council should put bollards up to stop people parking there."
A fellow shopper, Coppull granddad Jim McGhee, was also spurred into taking pictures of the cars.
The semi-retired businessman said: "I have no axe to grind but do feel tremendously antagonised by these utterly inconsiderate people.
"We often take our 18-month-old grandson into town on Saturday and access would have been impossible had we had his buggy with us.
"In fact, I saw one young lady have to get her child out of a buggy and lift the empty pram over the bonnet of a Mercedes car that was parked there.
"My understanding of the situation is that it is illegal to block a public right of way."
Paul Riley, group manager at Lancashire Parking Services: "Lancashire Parking Services is working closely with the local police and PCSOs in Chorley who can issue warning notices to vehicles parked causing an obstruction to other road users.
"Police can issue fines to vehicles parked on pavements or in places that cause an obstruction to wheelchair users, prams and pedestrians. Concerned residents can bring issues like this to the attention of the community police teams or Lancashire Parking Services."
