As this number plate things seems to have assumed great importance, I attach this:-


Vehicle Number Plates in the UK
There are strict rules set out that govern the layout, fonts and character specifications used on UK number plates. There are also general rules laid out on how number plates must be displayed. If these rules are not followed then it can be seen as an offence. General rules will include:



Number plates must be lit during the evenings
Registration marks must be readable and not covered by dirt
Vehicles must have number plates fixed to them
Number plates must be laid out in the correct size, colouring, font and spacing
Owners cannot alter or rearrange numbers and lettering on their number plates
Plates should follow the British Standard for number plates including the trademark of the plate supplier
No other images should be used on number plates except approved images such as the Euro flag and other flags
A non reflective border is optional
Punishments for Number Plate Offences
Incorrect number plate offences can lead to fines of up to £1000 for each specific number plate offence. It may be the case that a Notice of Intended Prosecution (NIP) will be affixed to car, for instance in a public car park, with a fixed penalty violation. There is no requirement for an NIP to be provided for number plate offences. There are sometimes defences available for this type of offence but misleading or lying to the courts can lead to larger fines. Police cameras are regularly used to catch drivers with dirty numbers plates or plates with incorrect spacing.


PS If I were a still a serving officer in UK I personally would be on the look out for people who break the law in a way which affects other citizens in a real way, not wasting police time on a number plate which has been slightly modified, as long as it was still legible.
