Design of on-road test routes: validity issues for assessment of functionally impaired drivers

Licensing authorities are faced with the challenge of designing on-road assessment procedures that are both valid and reliable. In the case of drivers with diagnosed medical conditions or disabilities, requirements for valid assessment need to be considered in relation to the kinds of functional impairments that might reduce driving competence and increase crash risk; an important determinant of assessment validity is the kind of test route used. This paper describes the characteristics of routes, including associated driving manoeuvres and traffic conditions, which are currently being used in Victoria, Australia by specialist occupational therapy driver assessors (OTDAs). Data were obtained by in-depth interviews of 22 OTDAs, representing 50 per cent of the total group active in Victoria, Australia at the time of this study; seven were based in rural or regional locations.
