Thousands of drivers will be handed back their motoring fines from this week after Essex County council agreed its bus lane road signs weren't clear enough.
The authority had issued nearly 30,000 penalty tickets to drivers in Colchester.
After a campaign by motorists, councillors admitted the signage on North Hill and High Street was unclear.
Essex County Council granted an amnesty on penalty charge notices issued to those motorists who used the re-introduced bus lanes in Colchester town centre prior to 12th Jan 2014.
Cllr David Finch, Leader of Essex County Council "Following the decision regarding an amnesty on penalty charge notices and a subsequent waiving of the fines, I am pleased to confirm that motorists should shortly all be in receipt of their refunds.
Essex County Council has also made a number of improvements to the road markings in Colchester town centre to make it clearer to motorists where the bus lanes are located. We are awaiting DfT authorisation for additional signage which will be installed as soon as authorisation is received."
