Objectives

To identify the prevalence of drugs among drivers.

To examine the nature of the effects which different drugs have on driving behaviour.

To devise techniques to address the problem by enforcing the law.

Methodology

  • Collect data on the extent of drug driving and monitor the success of new police enforcement techniques introduced in August 2000.

Key Findings

  • Assessment of impairment by police using FIT was supported by a forensic medical examiner (followed by clinical examination) in 77% of cases.

  • Roadside application of FIT demonstrated sensitivity of 65%, specificity of 77% and accuracy of 66%.

  • FIT is usable in its current form, however further development is required. Drug recognition skills of police were good.
