RSS speed laboratory receives
five-year seal of approval


Road Safety Support’s international speed test facility has retained its prestigious ISO 17025 accreditation after a major inspection and remains the only laboratory of its kind worldwide.

Five years after first receiving the accreditation, the United Kingdom Accreditation Service (UKAS) conducted a rigorous examination of the laboratory and its processes and confirmed that its high standards had been maintained.

Road Safety Support, a not-for-profit company, holds ISO 17025 for testing and calibrating speed cameras, vehicle speedometers, telematics and other speed measurement devices, either at its dedicated UK test track or on any road across the world. No other laboratory globally is accredited to do this.

The skilled laboratory team test devices to a known precision, proving beyond doubt that the technology is working within specified limits and that the evidence from it can be relied upon in court.

In 2019, the laboratory launched a new digital speedometer calibration method after an increase in the number of new vehicles fitted with electronic speedos. This posed a great problem for police forces and fleet suppliers, in particular, as they required a verifiable and accredited method of calibrating digital speedometers.

Traditionally, an analogue speedometer was removed from a vehicle and adjusted to read an accurate or close to true speed, as part of the calibration process. This method omitted the checking or calibration of the vehicle systems. 

Many modern vehicles now have digital speedometers that cannot be adjusted without compromising the vehicle; the Road Safety Support method service eliminates these concerns and provides a traceable calibration of the vehicle.

A large number of digital speedometers in police vehicles have now been expertly calibrated by Road Safety Support, for forces including Cumbria, Warwickshire, North Wales. Greater Manchester, Northamptonshire, Essex, South Wales and Cheshire.

News of the method is also spreading to managers of private fleets who recognise the importance of ensuring the accuracy of their speedometers, giving them and their drivers peace of mind that their vehicles are travelling at a verifiable speed.

As the pressure on companies to meet Environmental, Social and Governance (ESG) goals as well as improved health and safety policies increases, the service is now being widely recognised by fleet and health and safety managers across the public and private sectors.
