Speed cameras: the myths exposed - You can doctor your numberplate

'Cling film or 'magic' sprays can be used on number plates to reflect the speed camera flash, making your plate 'unreadable'.'

No.

In tests using speed cameras, the leading brand of magic spray did not mask the number plate at all.

If you do resort to this tactic you could be charged with attempting to pervert the course of justice.

Having plates that are so dirty that they're unreadable is also an offence and many police forces are actively tracking down repeat offenders who trigger cameras with 'dodgy' plates.
