Description and rationale

The lack of compliance among teen drivers with GDL rules reduces their effectiveness. License plate identifiers (decals) serve to facilitate police enforcement efforts by indicating whether a young driver on the road is subject to GDL rules. This can have a deterrent effect to ensure inexperienced drivers are not driving in high risk conditions. Studies in New Jersey revealed that the introduction of a decals requirement was associated with both short-term and longer-term crash reduction effects for initial license holders.1
