The study explored the factors that contribute to vehicle runaways using a multi-method approach, which included: i) conducting a literature search, ii) reviewing relevant incidents reported under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations, iii) carrying out an online consultation survey of trade association members, and iv) conducting interviews with drivers, supervisors and manufacturers.
Failure to apply the cab handbrake and/or trailer parking brake was identified as the primary reason contributing to vehicle runaways. A combination of individual, job and organisational factors were identified as affecting drivers’ behaviours, and particularly the extent to which the cab handbrake and/or trailer parking brake would be applied. Provision of easily accessible controls, physical solutions (e.g. interlocks, cab alarms), supervision and raising risk awareness were control measures identified that could help prevent vehicle runaways.
