Dan is quite correct in that it is usual to stop motorists suspected of speeding in these circumstances. However, a few words of warning and clarification.
With the �traditional� safety camera process, the photographs taken can rarely identify the driver as most of the cameras currently in use work from the rear of the vehicle. In any case it is not necessary for the prosecuting authorities to identify the driver at the time of the offence. The registered keeper is required to provide these details.
The request for this information usually forms the first part of the �fixed penalty� process and is usually accompanied by a �conditional fixed penalty offer�. This offer invites the driver to accept guilt and pay a fixed penalty (�60 and 3 points) without going to court. The offer will not be made if the speed is excessive and will not be continued if the 3 points awarded to the driver would take him to 12 or more.
Failure to provide the information within the prescribed timescales is an offence under Section 172 of the Road Traffic Act and attracts a fine (of more than �60) and three penalty points against the registered keeper.
Whilst this process can be used following detection by hand held radar traps, it is not usual.
