Police Laser Devises - can they target the back of your car?

Can police laser devices measure your speed from the back of your car or only from the front as you drive towards them?

Also, if you are being followed by a police car / bike, do they measure your speed using a laser or something else?

While we're waiting for BiB to sign on for the PH shift

GATSOs shoot up the chuff and other laser devices could do so.

Bikes and cars on 'following checks' or when stationary using markers and timings, either use a calibrated speedo to take a reading there and then, or calculations for speed using fixed markers and the time taken to travel between them - some absolute some in comparison to their vehicle if it's moving.

Purely on a note of general interest there are serious concerns over the shortcomings of two laser devices, the LTI 2020 and the latest Pro Laser III.

Yes. I got done by a scammer with an LTI20-20 hiding behind some signs so you couldn't see him until you'd gone past.

My brother got caught driving away from them as well.

For the Lti2020, receding targets are identified by the "-" sign in front of the speed reading on the display.

Also for the LTI 2020 device, receding Courtroom walls are identified by the expression on the defendant's face. Hopefully receding magistrates sat on the bench are indicated by a 'not guilty' verdict
