The enforcement of a civil penalty charge—for example a penalty charge arising from parking, certain moving traffic contraventions, or from a road user charging scheme—is a matter for the issuing local authority. The Government are not aware of local authorities making arrangements to monitor vehicles leaving the UK for this purpose.
The enforcement of criminal penalties is an operational matter for HM Courts Service. HMCS does not routinely monitor vehicles leaving ports for the purpose of fine enforcement. The EU Framework on Mutual Recognition of Financial Penalties, once implemented, should ensure that future offenders from other EU member states pay the penalty for the criminal offences they commit.
