Driver profilers are widely used to understand driver attitudes, behaviours, and risk tendencies. They can offer quick insights across large driver groups, helping fleets spot trends and guide training decisions.

However, because profilers rely on self-reported answers, they don’t always reflect real on-road behaviour — and results can be influenced by guesswork, memory, or the desire to give the “right” answer.

Understanding where profilers add value — and where they fall short — is essential for building a fair and effective approach to driver competence.

Key insights from this paper:

• What driver profilers measure — and what they miss
• Why self-report tools can be biased or unreliable
• How profiler validity affects recruitment and training decisions
• When profilers are useful in fleet management
• Why behavioural and scenario-based assessments provide stronger evidence

Using profilers as one part of a wider competence strategy helps fleets make safer, fairer, and more informed decisions.
