“…There is increasing evidence confirming the effectiveness of GDL, which acts as a form of exposure control by allowing novices to gain more driving experience over an extended period in lower risk circumstances. These programmes vary widely by jurisdiction; however, extended Learner and intermediate periods with greater restrictions such as passenger limits and night‐driving curfews have been shown to result in the greatest improvements in young novice driver road safety (Williams, Chaudhary, Tefft, & Tison, 2010). Reported non‐compliance by young novice drivers (e.g., in New Zealand, Harre, Field, & Kirkwood, 1996) and haphazard enforcement (Rice, Peek‐Asa, & Kraus, 2004), the issuing of warnings instead of punishment for infringement of road rules (Rhodes, Brown, & Edison, 2005), and failure to detect non‐compliance (Scott‐Parker, Watson, King, & Hyde, under review) weaken such interventions.…”
