What is the research evidence for the Driver Risk Index™?

The Driver Risk Index™ is the commercial name for our online driver risk assessment with a 30+ year research history underpinning its development. The scales used in the Driver Risk Index™ have been the subject of over 90 published academic papers. The scales have been through the standard phases of psychometric development, from the initial theoretical underpinning, through various methodological and statistical tests to practical use for driver risk assessment and management in a variety of different organisations. It has been reliably shown that the Driver Risk Index™ scales are personality-based emotional responses to driving. The scales are associated with driver behaviours, errors and crash risk.
