Dstl develops the first effective test for drug impairment

The Defence Science and Technology Laboratory (Dstl) is developing a roadside test to measure the effects of drugs on drivers.

The test, DIRECT™ (Driver Impairment Roadside Evaluation and Competency Test), is computer-based, and can be easily carried on a laptop. It can show in what areas and to what extent people have been affected by drugs, and will be the first standard, objective test that can measure how an individual’s performance has been affected and whether they are capable of driving safely.

DIRECT™ is primarily aimed at the testing of drivers who may be impaired by drugs, but can also be applied to other skills including operating machinery and driving other vehicles such as aircraft, and can cover all drugs including alcohol, medicinal drugs and illicit drugs.

The prototype of DIRECT™ is now nearing completion and is initially being developed to provide the police with an effective roadside test for drug-impaired drivers. It is expected that it will act as a deterrent and an on-the-spot test that will reduce the number of road accidents currently caused by people driving under the influence of drugs.

Adrian Clark, Project Manager at Dstl comment:

“Until now, there has not been a test that can effectively prove impairment due to drug taking. DIRECT™ does not operate on a zero tolerance basis but will objectively measure the person’s ability to drive safely. The test is an early prototype which can now be taken forward to the test and evaluation stage.

It is easy to use and can be carried around in the patrol car helping police confirm their initial thoughts that the driver is under the influence of drugs. The test could also be used in the workplace ensuring that employees who are using heavy machinery are not endangering themselves or their colleagues.”
