Alcool, drogues, médicaments et sécurité routière en Belgique. Belgian Toxicology and Trauma Study Research Group

The BTTS study (Belgian Toxicology and Trauma Study) was performed in Belgium between January 15th 1995 and June 15th 1996. The purpose was to investigate how frequently the drivers involved in road accidents were driving under the influence of psychotropic drugs. Two thousand fifty-three blood tests were performed of which 207 in the Liege region. The results obtained at the national level are compared to those obtained at the level of the Liege region. In both cases, the BTTS study allows the conclusion that a considerable proportion of drivers involved in road accidents resulting in significant traumatic consequences were driving under the influence of substances with psychotropic properties.
