Suspended jail and curfew for driver
who used speed camera jammer


A driver who installed a laser jamming device in his work van to avoid speeding tickets has been given a suspended jail sentence, ordered to pay £3000 and placed under curfew for two months.

A jury at Swansea Crown Court found Jason Moore guilty of perverting the course of justice after he fitted a Laser Star jamming device to a VW Transporter van to prevent a laser speed camera operator, employed by Dyfed-Powys Police, from establishing the speed of the vehicle.

James Hartson, prosecuting, told the court that in September 2018, the van was seen being driven at high speed as it approached the speed camera located near to Nantyci Showground on the A40, St Clears, approaching Camarthen.

When the camera operator attempted to measure the vehicle’s speed, an error message was indicated on the device. However, the operator had been trained by experts at Road Safety Support to recognise the unusual circumstances for this error message to be shown.

As members of Road Safety Support, Dyfed-Powys Police sought the specialist help of Steve Callaghan, the company’s forensic video analyst and laser jammer expert.

A copy of the video was sent to Mr Callaghan and he confirmed that there was a suspect device visible in the video images. He also spotted that the laser jammer could be seen to be flashing light from the grille of the van as the error messages were produced by the laser speedmeter.

As a result of Mr Callaghan’s preliminary examination and advice to Dyfed-Powys Police, the van was recovered to allow the device to be tested and recovered for evidence.

A full report was made on the findings of the examination and the circumstances of the incident where the speed could not be read. Road Safety Support found the speed of the van to be 72 mph, despite its maximum permitted speed being 60 mph.

Mr Moore claimed he didn’t know that the Laser Star jamming system was capable of blocking the speed measurement function of a police speedmeter. He claimed that he had bought the device solely because it had a parking sensor function.

Mr Moore appointed David Winstanley, a retired police collision investigator, who claimed to have sufficient expertise in laser and video systems to act as his expert witness.

Mr Winstanley insisted that the Laser Star is sold as a ‘parking sensor’ and should not be considered as primarily a laser jamming device.

In response, Mr Callaghan explained that the use of a laser beam to detect parking obstructions was wholly inappropriate and largely useless. He explained that, in any case, a parking sensor need not be programmed to jam a laser speedmeter. The Laser Star also has a list of speed cameras in its instructions and marketing that it can jam; not a property of a parking sensor.

Mr Moore also stated in his defence that the security company that he worked for insisted that employees pay for any damage caused to work vehicles. He claimed that he fitted the device to reduce the risk of damage.

Moore was found guilty by a jury and sentenced at Swansea Crown Court on October 18, 2021.

Judge Vosper QC called Moore’s defence “spurious” stating that he “wasn’t surprised that the jury rejected his defence.”

Moore was sentenced to 32 weeks’ custody, suspended for 2 years. He was also ordered to pay costs and fines totalling £3,000 and a curfew was imposed for two months.
