Is there a recommended period for the issue of warning notices prior to the issue of Penalty Charge Notices (PCNs)?
For the first six months, motorists who break the rules will be sent a warning letter for each first-time infringement of their vehicle at each location. Any subsequent breach during this period will lead to a penalty charge notice.
After that first six months, warning letters will end, and all breaches will result in a penalty charge notice.
Any new sites will be subject to the same requirements above.
