Overview Young novice drivers The Queensland graduated driver licensing (GDL) context –Pre-July 2007 (‘Original-GDL’) –Post-July 2007 (‘Enhanced-GDL’) Experiences of Learners in Queensland’s enhanced-GDL program –Pre-/post-July 2007 comparison –Post-July 2007 only Implications Strengths and limitations 2

Young Novice Drivers [1] Statistics –Australia, year olds: 13% of population, 26% of driver fatalities –Queensland, 2010 Young drivers were involved in 36% of all crashes resulting in at least one person being hospitalised –Queensland, 1 July 2004 – 30 June 2009 The young driver was at fault in 81% of fatalities and 72% of hospitalisations 4
Young Novice Drivers [2] Greatest risk to novices –During the first 6 months of independent driving Graduated driver licensing –Gradual exposure to conditions of increased risk –Learner period provides opportunity for foundation of safe driving to reduce risk during later independent driving 5

Post July-2007 When did Learners have most driving practice? –One third “throughout” BUT –50% of males & 60% of females “mainly at end” Continued practising after submitting logbook and waiting for practical driving assessment? –95% yes Logbook accuracy –83% logbook accurate –13% ‘some rounding up’ –4% included extra hours 13
Pre-Licence driving –Reported by 12% of Learners Unsupervised driving –Reported by 12% of Learners Speeding –70% of Learners reported speeding by up to 10 km/hr –32% of Learners reported speeding by km/hr –13% of Learners reported speeding by > 20 km/h –Learners continue speeding at greater amounts and more frequently as Provisional 1 (P1) drivers Compliance with GDL/ General Rules [1] 14
Punishment avoidance –Some Learners (and P1) drivers reported their parents took the demerit points on their behalf –Some Learners successfully talked themselves out of a ticket for the same offence on multiple occasions, or multiple simultaneous offences were missed by Police –One quarter of males reported that they actively avoided on-road Police presence Compliance with GDL/ General Rules [2] 15
Implications [1] Longer Learner period, same age L P –Overall longer Learner duration BUT no difference in age of independent licensure –BUT ‘Older’ young novices report more difficulty/ longer Learner duration/ more unsupervised driving/ greater logbook inaccuracy Practice –More practice, = more safe? (reduced crashes/ offences) –Less difficulty in obtaining supervised practice (females) –‘Most at end’: persistent practice effects vs ‘cramming’? –Not practising after submitting logbook: focus upon accruing hours? 16
Implications [2] Non-compliance and punishment-avoidance –Suggests supervisors (most commonly parents and friends) are complicit, or less-effective than they could be {NB will be discussed further by Prof Barry Watson} –Punishment-avoiders/ Police-avoiders more risky drivers in general 17
Strengths and Limitations Self-report data (surveys, interviews) –Difficult to investigate behaviours any other way Low response rate in online surveys/ high attrition for longitudinal research, despite incentives –Young novice drivers difficult to recruit/ retain Greater participation of females –Separate gender analyses Generalisability of findings (small, matched sample for GDL-comparison) –Results need to be confirmed by larger-scale evaluations 18
