The role of driver education in the licensing process in Quebec.

Problem: In many jurisdictions, driver education (DE) graduates, compared to non-graduates, are granted a time-discount that allows them to drive unsupervised several months earlier, despite little evidence of a safety benefit and consistent evidence of increased crash risk. Confounding factors may be threatening the validity of DE evaluations. A theoretical framework called the "licensing process" (LP) is proposed to identify and explore potential confounding factors in DE evaluations.

Wireless telephones and the risk of road crashes.

In light of the rapidly increasing development of the cell phone market, the use of such equipment while driving raises the question of whether it is associated with an increased accident risk; and if so, what is its magnitude. This research is an epidemiological study on two large cohorts, namely users and non-users of cell phones, with the objective of verifying whether an association exists between cell phone use and road crashes, separating those with injuries. The Société de l'Assurance Automobile du Québec (SAAQ) mailed a questionnaire and letter of consent to 175000 licence holders for passenger vehicles.

Three year injury crash records of new licensees with suspensions or invalidity periods lasting 90 days or more.

A subset of new licensees, namely the ones with suspensions or invalidity periods of at least 90 days are studied. This subpopulation is comprised of 3,550 men and 1,295 women for whom the study file contains age, gender, licensing exam performance, and the dates all police reported crashes for the first three years after licensing. This group is compared with the complementary subpopulation of 53,069 men and 58,464 women.

Impact of diabetes on crash risks of truck-permit holders and commercial drivers.

Objective: The U.S. and some Canadian government agencies have waived commercial license restrictions for some insulin-using diabetic drivers.
