UK: Roadside computer 'games' aim to trap drivers on drugs
David Millward The Telegraph
Wednesday 23 Nov 2005 A computer test for motorists driving while under the influence of drugs was unveiled by the Home Office yesterday. The first machines are likely to be in the hands of patrol officers within two years when the Government will ask police forces to test the technology. Last December police were given powers to order motorists to carry out 1950s-style roadside tests, which would enable patrols to make a preliminary assessment of whether somebody was fit to drive, even if there was no evidence of alcohol. They included instructing drivers to walk in a straight line, stand on one leg or touch their nose with their index finger. These tests were introduced as research revealed that there was an increasing number of drivers getting behind the wheel having taken drugs. In Derbyshire 31 out of 92 motorists stopped in a pilot study tested positive for an array of narcotics including cannabis and heroin. Unlike alcohol, drugs cannot be detected by a Breathalyser. Home Office scientists believe that the traditional impairment tests are too subjective and have turned to technology to find a 21st century solution. Anyone who either fails or refuses to take the test will be taken to the police station for a blood test. The machine used yesterday was a Sony Vaio handheld personal computer, available in high street stores. It was loaded with a number of "games" designed to assess the reactions of a motorist. Drivers would be tested not only on their speed and dexterity but also the accuracy with which they performed the task. This is because while cannabis can slow reaction time, amphetamines quicken it - but also makes individuals more prone to error, a symptom which can be fatal when driving. Home Office scientists are looking for a device costing between UKP500 and UKP1,000 which can be issued to car patrols. Assuming they eventually become as prevalent as Breathalysers, even provincial forces could be facing bills of several hundred thousand pounds to equip their cars. Meanwhile Home Office scientists are also working on a portable "drugalyser". Whitehall hopes that a version capable of being carried by a police car could be ready for testing in three years.
