As Civil Enforcement Officers / Parking Attendants walk around their beat, they enter details about cars parked at parking meters into their handheld computers. This includes the meter number, the registration number of the car, the amount of time a car has remaining on the meter (with consequent expiry time) and the position of the front and rear valves of the pavement-facing car tyres (given as clock points - e.g. 9 means 9 o'clock).
Offence code: 07
Explanation: Parked with payment made to extend the stay beyond the initial time ('meter feeding'). You may not pay extra money into a meter/pay and display machine to extend the time you have already purchased - even if this does not take you past the maximum time allowed at that parking place.
