Transport for London is installing two forward-facing speed cameras to aid identification of speeding motorists.
The trial cameras on Upper Thames Street will take a digital image of the front of speeding cars at the same time as a traditional speed camera takes an image from the rear. This will prevent people from claiming they weren't at the wheel.
Chris Lines, head of the London Road Safety Unit, Transport for London, said: "Speed is a contributory factor in a third of fatalities in London and we hope trialling these cameras will enable us to stop motorists who endanger lives by speeding." We're assuming Lines means excess speed, but the source of his data is unknown.
And don't think that you'll be safe from a ticket if you slow down or stop – Westminster Council has just got two new Smart Fortwos, both equipped with CCTV to monitor parking offences.
