A study to measure the incidence of driving under suspension in the Greater Moncton area.

Roadside checkpoints were used to determine the percentage of motorists driving while suspended (DWS) during various times of the day. These data showed that the percentage of motorists DWS was 57% of the expected value relative to their representation among all drivers. Data also showed that suspended drivers make up a higher percentage of drivers on the road after midnight. Results also indicated that 90% of suspended drivers stopped in this study produced a driving permit even though they are required to surrender it when suspended. In order to compare data collected at roadside checkpoints with self-report data. a questionnaire was administered to 456 persons taking a re-education course for first offenders and 68 participants taking a re-education course for second offenders. The results indicated that participants under-represented their own incidence of DWS. However, when asked about the driving behavior of other suspended drivers, their estimates were much closer to the data obtained with the roadside survey.
