Police speed detectors 'reliable' | |
(about 2 hours later) | |
Police have reversed a decision to stop traffic officers in Scotland using handheld speed detecting equipment. | |
There had been fears the Visual Average Speed Computer and Recorder (Vascar) system could be affected by police radio waves. | |
But the Association of Chief Police Officers in Scotland (Acpos) said Home Office scientists had now confirmed that they were reliable. | |
Acpos has reversed the initial advice to stop using the handheld devices. | |
Road policing units had been told to employ alternatives to the system until further notice. | |
It had been suggested police radios could be causing faults in the speed detectors. We took the precaution of advising forces of a potential issue with the equipment and have now clarified the situation Chief Constable Kevin SmithAcpos | |
However, Acpos said it had now received advice from the Home Office Scientific Development Branch that there was no possibility of interference when guidelines were followed by officers. | |
Acpos said that the equipment had been tested and found to operate properly under the appropriate guidelines. | |
Chief Constable Kevin Smith, chairman of the road policing business area of Acpos, said: "We are confident that the speed detection equipment being used by Scottish forces is reliable and as such we have advised forces that it should be used as normal. | |
"We took the precaution of advising forces of a potential issue with the equipment and have now clarified the situation." | |
