Driving and Licensing Experiences of Learner Drivers in Queensland:
Comparing pre-and post-July 2007Presenter: Bridie Scott-Parker (PhD Candidate)
Co-Authors Ms Lyndel Bates, Prof Barry Watson, Dr Mark King, Dr Melissa Hyde
Extent of the Problem
• Young drivers (17-24 yrs), Queensland, 2008 13% of licensed driver/ rider population 20% of persons killed 33% of all fatalities arose from crashes involving
young drivers/ riders
3
Graduated Driver Licensing (GDL) Novice gains more supervised driving experience
under lower-risk driving conditions over an extended duration
Enhanced GDL for Learners, Queensland July 2007 Minimum age 16 years, minimum duration 1 year Must record 100 hours supervised practice recorded in
logbook, including 10 hours of night driving First 10 hours of professional supervision equates to 30
logbook hours Enhanced GDL for Provisional period at same time

Study Aims
1. To document the experiences of Learners within the current-GDL program (introduced July 2007)
2. To compare some of the experiences of Learners within the current-GDL program with those of Learners within the former-GDL program (pre-July 2007)
5
Method Former-GDL Program Current-GDL Program
Recruitment
• 2006, pre-July 2007• Recruited in-person from Brisbane and Townsville Licensing Centres
• April, May, June 2010• Recruited Queensland-wide with Flyer when progressed from Learner to Provisional Licence
Participants (Provisional licence)
(17-19 years)
149 Novices 75 females74 males
1162 Novices681 females481 males
Design and Procedure
(Longitudinal research)
• 35 minute telephone interview• Second telephone interview 1 year later
• 30 minute online or paper survey• Two further 20 minute surveys after 6 and 12 months

Additional Results – Current-GDL only
When did you get most of your driving practice? One third “from the beginning”; 50% of males and 60% of females “mainly at the end” of the Learner period
Did you continue practising after submitting your logbook and the practical driving assessment? 94.8% yes
How accurate were the entries in your logbook? 83.2% of novices reported their logbook accurate 12.8% of novices reported some rounding up of hours 4.0% of novices reported including extra hours

Strengths and Limitations
• Former-GDL/ Current-GDL/ Comparison– Representativeness of samples– Accuracy of responses– Key measures explored– Longitudinal research
• Emerging results need to be confirmed by larger-scale evaluations
12
In Conclusion
• Novices gained more supervised driving experience
• Parents supervising Learners more• No change in number of hours of supervision
provided by driving instructors• Novices reported less crash-involvement• No increase in unsupervised driving• Novices reported less difficulty obtaining
supervised driving practice
