controlled areas to local authorities; other parking offences such as any involving penalty points and/or those not involving the 1991 Act (or equivalent in Northern Ireland) remain enforceable by traffic wardens. Traffic wardens in the Metropolitan Police could be promoted to traffic warden supervisor, traffic warden controller, senior traffic warden controller, and area traffic warden controller. Most "traffic wardens" are now non-existent and have, in almost all areas, been replaced by local authority civil enforcement officers/parking wardens/parking attendants etc. Traffic officers of the former Highways Agency and current Highways England (England and Wales) operate under the Traffic Management Act 2004 and have various powers to deal with vehicles on a "relevant road" (chiefly motorways and trunk roads) which on other roads would be dealt with as parking offences by police or local authorities; this includes the power to remove such vehicles.
