Förekomst av alkohol och droger hos förare av lastbil och buss som varit inblandade i dödsolyckor och olyckor med svåra personskador


The aim of this study was to improve the knowledge about the presence of alcohol, drugs and medicine among drivers of trucks or busses involved in fatal accidents and accidents with severe injuries. The study is based on material from two different databases, the Swedish Transport Administrations in-depth study database and the Swedish Traffic Accident Data Acquisition (Strada), owned by The Swedish Transport Agency. The survey of the presence of substances and background variables such as gender, age and type of accident among drivers under influence is presented in this study and based on accidents that occurred 2008–2015. The study includes 614 fatal accidents from the in-depth study database and 3381 accidents with severe injuries from Strada.

For fatally injured drivers of trucks and busses in the in-depth database presence of alcohol was found in 15 percent, illegal drugs in 6 percent and medicine in 9 percent. Compared to the corresponding figure for drivers of cars, the presence of alcohol is lower, whereas the presence for illegal drugs and medicine, is at the same level. The presence is much lower when studying all drivers of trucks and busses involved in fatal accidents disregarding the drivers level of injury. The presence of alcohol among the drivers were 2 percent and 1 percent for illegal drugs respectively medicine. There are though differences between the type of vehicle driven. Among drivers of lighter trucks 16 of 156 drivers (10%) had presence of alcohol and/or illegal drugs. For drivers of trucks 4 of 369 (1%) and drivers of busses 0 of 96 drivers (0%) where under the influence of alcohol and/or illegal drugs.
