Queensland introduced substantially increased penalties (fine and demerit points) for illegal mobile phone use while driving. The introduction of new technology enforcement cameras then followed. A survey was undertaken at three points in time to understand whether there was a change in the attitudes, behaviours, and/or future intentions of a sample of Queensland drivers to illegal mobile phone use while driving. The results from the surveys show a reduction over time in the proportion of drivers who self-reported using a mobile phone illegally while driving, from 52.3% in the initial survey, to 47.6% in the third survey. However, the findings also show there remains the opportunity to increase the perception of certainty of detection, and minimise events of non-detection, for those who continue to use a mobile phone illegally while driving.
