Driving under the influence of drugs part 2: research into the work processes and saliva drug tester, conditions regarding storage and transport of blood and data registration (full text only available in Dutch)


With effect from 1 July 2017, Article 8 of the Road Traffic Act has been expanded with paragraph 5 to better tackle driving under the influence of drugs – or as we call here: drugged driving. This can contribute to increasing road safety. The amendment to the law provides, among other things, for a set of instruments with which the police and the judicial authorities can more easily determine the use of drugs. The police are thus authorized to test road users for drug use by means of a saliva drug tester and by examining the psychomotor functions and eye and speech functions (by means of a psychomotor test or PMT).

The research has the following threefold problem definition (main questions) that are subsequently elaborated into research questions:

  1. How is the drug testing process going?
  2. What requirements should be set for the storage and transport of blood taken as part of a drug test, so that the degradation in the quantities of substances does not lead to the result being wrongly below the limits of the tested drugs?
  3. What information is needed for the evaluation of the law in five years and is this information collected and stored in current practice?
