Graduated drivers licensing and traffic injury-attributable emergency department visits in Alberta, an interrupted time series study

Removing GDL restrictions in Alberta led to immediate increases in MVC-related ED visits, particularly among motorcycle users, younger age groups, and males. Minimal ongoing trends suggest the effects were largely immediate and no statistically significant lasting impacts are noted. These findings highlight potential safety risks from relaxing licensing restrictions and the need for targeted interventions for high-risk groups as other provinces consider similar policy changes.
