Working in light vehicles--a review and conceptual model for occupational health and safety

Occupational light vehicle (OLV) use is the leading cause of work related traumatic deaths in Westernised countries. Previous research has focused primarily on narrow contexts of OLV-use such as corporate fleet vehicles. We have proposed a comprehensive systems model for OLV-use to provide a framework for identifying research needs and proposing policy and practice interventions. This model presents the worker as the locus of injury at the centre of work- and road-related determinants of injury. Using this model, we reviewed existing knowledge and found most studies focused only on company car drivers, neglecting OLV-users in non-traditional employment arrangements and those using other vehicle types. Environmental exposures, work design factors and risk and protective factors for the wider OLV-user population are inadequately researched. Neither road- nor work-related policy appropriately addresses OLV-use, and population surveillance relies largely on inadequate workers compensation insurance data. This review demonstrates that there are significant gaps in understanding the problem of OLV-use and a need for further research integrating public health, insurance and road safety responses. The model provides a framework for understanding the theory of OLV-use OHS and guidance for urgently needed intervention research, policy and practice.
