Highways England has declared that 192,293 Penalty Charge Notices (PCNs) have been passed onto the European Debt Recovery Agency since the Dartford Crossing became a free flow crossing.Responding to a Freedom of Information Request, the numbers involved cover the period from 30th November, when the toll barriers were phased out, to 7th July.There have been around half a million crossings by non-UK registered vehicles so far during chargeable hours (6am-10pm).Highways England says it will publish how many of these PCNs have been subsequently paid in due course.  It says it can take longer to recover unpaid money from foreign vehicles because it can take up to two months to receive the information about registered keepers abroad.In the response, Highways England stressed it has provided information about the Dart Charge in ten languages, distributed at ports, on ferries and through European motoring organisations.It says it is serious about pursuing non-payers, regardless of their country of origin.
