Research using the driver behaviour questionnaire (DBQ) has found that aberrant driving behaviours can be categorised into: errors, lapses and violations (and aggressive violations, depending on the version of the DBQ used). There is also extensive evidence that it is only the 'violations' score which is significantly correlated with, and predictive of, crash involvement. This consistency has been found both across different samples and different countries. However, recent research conducted on those driving cars in a work-related context has found a different factor structure and a different pattern of correlations with crash involvement. The present study extends this research by investigating the factor structure of the DBQ and the relationship between aberrant driving behaviour and crash involvement for a sample of truck drivers. Factor analysis yielded a four factor solution, that broadly replicated the four hypothetical factors (errors, lapses, violations and aggressive violations) found in the general driving population. Only the violations factor was found to be significantly predictive of crash involvement. This research provides evidence of the robust nature of the DBQ findings in populations other than the drivers of private motor vehicles.
