In the traffic domain it is commonly known that sleepiness is a highlycontributing factor in traffic accidents. Research has shown that sleepinessamong drivers is present in about 16-23 % of all car accidents. In the aviation andrailway industry a method or framework with some shared influences from theHuman Factors approach, called Fatigue Risk Management (FRM) has been usedto investigate how social and organisational factors affect the personnel’s level ofsleepiness. The overall aims of this study are to investigate how truck drivers’experience, fight and counteract sleepiness in their daily work environment. Theresults show that drivers face a wide variety of sleep contributing factors,stemming from both organisational factors and individual behaviour. Possibleways of counteracting truck driver sleepiness, concerning both the individual andthe organisation, are also suggested.
