Police are cracking down on motorists driving the wrong way along streets in Chorley town centre.
Market Street was reopened to traffic in November, after being pedestrianised for more than 10 years.
It is a 12-month trial by Chorley Council to encourage people to visit the town centre and boost trade.

But there have been problems with vehicles ignoring no-entry signs and travelling the wrong way along Market Street and Chapel Street.
Officers from Chorley neighbourhood policing team launched an operation last month to remind and educate drivers about the new
They are now issuing tickets to anyone caught driving the wrong way.
The tickets can lead to a fine and points on the motorist’s driving licence.
The neighbourhood policing team took action after receiving a number of complaints from business owners, residents and shoppers in the town centre.
PC Nic Barff-Lewis said: “A team has been working in the town centre in the morning and the evening.
“First of all we were advising and then issuing tickets.
“The problem is a lot better since we have done that.
“In the New Year so far, we have not had any people misusing the system, but we want to make people aware the no-entry signs are there for a reason – for the safety of people in the town centre.
“Going through a no-entry is three points on your licence and you could get a fine.”
Coun Peter Wilson, deputy leader of Chorley Council, said Market Street was reopened to traffic and extra parking spaces created after requests from traders.
He felt it was going well so far, but urged drivers to follow the rules of the road.
Coun Wilson said: “There’s no excuse for motorists to drive the wrong way along Market Street.
“It’s dangerous for other motorists and pedestrians.
“When it started happening, when we reopened the road to traffic last November, we installed new no-entry signs to ensure traffic heading northbound turns up St George’s Street.”
