How does a hand-held radar meter work?
This works just like any radar-controlled GATSO but displays the speed on the back for the operator to see. It’s then up to the operator’s discretion whether or not to stop you. You can buy so-called ‘radar-scattering number plate covers’ which do actually scatter the returning radar so the gun can’t get a reading. This does, of course, rely on the Policeman having pointed the gun at your number plate in the first place – generally they don’t as any nearly flat surface will do (headlights, bumpers, etc.).
