Drivers face being caught out by a new 'bus gate' on Deansgate in Manchester city centre. Now operational 24-hours-a-day, the restrictions mean only buses, taxis and cycles can travel south - between the junctions for Blackfriars to King Street West.
It's part of the council's vision to transform the area around the major city centre street.
For the first two weeks, only warning notices will be issued to drivers who fail to follow the new rules. No Penalty Charge Notices (PCNs) will be issued until February 27.
