PETA meters at Bridgend
South Wales Police had a small number of the PETA meters which were maintained at Bridgend depot and it was thought that on some odd occasions the meters were deployed while the annual calibration was a bit out of date, often indicated by a panicked look on a traffic officer's face and a request to re-calibrate the device as soon as possible.
The new Bridgend depot was situated towards the bottom of Litchard Hill, a nice steady drop from Sarn Common (where the M4 junction 36 is now) and that hill was a favourite site for the police to site a speed trap; we all knew that!
One morning, a WT at Bridgend, who shall remain nameless but for the benefit of this story we'll call him Ron Morgan arrived at work about ten minutes late having a bit of a tantrum and laughing at the same time, you've guessed it, he'd been stopped in the speed trap.
As was normal procedure, the officers offered the accused the opportunity to examine the equipment, usually declined by Joe Public, but on this occasion the offer was accepted.
Ron duly checked the operating angle to the road, the 30 and 70 mph calibration points and found everything in order, then asked to see the log book for the equipment, only to find that not only was the radar set well within its calibration period but the technician who had carried out the job was ..... Ron Morgan!
