Graduated driver licensing research in 2004 and 2005

This is the second update of research on graduated driver licensing (GDL) and teenage drivers and results have strengthened the case for GDL, for nighttime and passenger restrictions, and for extended supervised driving practice.

Abstract

This is the second update of research on graduated driver licensing (GDL) and teenage drivers. It briefly summarizes research in progress and research published since the January 2004 update (Hedlund, J. & Compton, R. [2004]. Graduated driver licensing research in 2003 and beyond. Journal of Safety Research 35(1), 5-11). Research has been very active, especially on teenage driver risk factors, GDL program evaluations, the role of parents in managing and training their teenage drivers, and driver education. Results have strengthened the case for GDL, for nighttime and passenger restrictions, and for extended supervised driving practice.
