Purpose and goal

DRUID (Driving under the Influence of Drugs, Alcohol and Medicine)VTI´s part comprise both experimental studies, where VTI´s advanced driving simulator will be used to study the effect of drugs in combination with sleepiness on driving behaviour, and filed studies where the prevalence of psychoactive substances on the roads will be observed. This will be compared to the prevalence of substances of drivers involved in accidents. VTI is also responsible for a part that aims at studying the underlying factors to why people are driving when intoxicated.

Expected results and effects

- Knowledge on the effects of drugs and medicines on driver behaviour. - Recommendations on suitable legal limits for the most commonly used substances - Information on the prevalence of the most commonly used substances on the roads - The prevalence of these drugs among accident involved drivers. - Information on the underlying factors to why people are driving when intoxicated.

Planned approach and implementation

One part is designed as a simulator study where the test person comes to the lab in the afternoon taking the correct doze dextroamphetamine alternatively placebo. Thereafter they will drive once as an awake condition and twice more during the night with increasing sleepiness and decreasing effect of the drug. The field observations will be carried out as a statistically representative selection study. In depth intervjues will be carried out to study the underlying factors to why people are driving when intoxicated.
