Abstract

This paper aims to add to the sparse research on patterns of traffic offending in young novice drivers by examining the trajectories of young Australian novices throughout the graduated driving licensing system (GDLS). Data on licensing, crashes and traffic offences for all persons aged under 25 years first licensed from July 2007 to June 2008 in New South Wales were supplied by transport authorities, with follow-up to January 2014. Eight hierarchical categories of offence were defined by seriousness. Total numbers of offences per month were plotted for one year after initial licensure while under supervision (L), after transitions to the first (P1) and second (P2) provisional licence phases and to unrestricted licensure (U). After excluding novices not transiting to P1, 75,470 novices (51.5 % male, 77.7 % 16 years old at L) remained. Of these 63,070 had a year of follow-up after P2 (52.5 % male, 82.3 % 16 years old at L) and 28,861 had a year of follow-up after U (55.5 % males, 91.7 % 16 years old at L), Offences were uncommon under at L but spiked after P1 and again after P2. Omitting GDLS offences there was a small increase after U. Patterns were broadly similar by age at L and time in L. Novices aged at least 18 years at L had the highest offence rates in the learner phase; those aged 17 years at L had the highest rates in P1 and P2. The longer novices spent in the supervised driving phase the lower their subsequent offence rates even allowing for age at P1. Urban or regional residence had little influence on offence rates but lower aggregate socio-economic status as measured by a census-derived index was associated with appreciably higher offence rates. Speeding was the most common offence type; dangerous/negligent driving was common immediately after P1, declining thereafter. These results are in broad agreement with previous research in noting the increase in offending as GDLS restrictions eased. They highlight the need for better understanding of the function of a GDLS in improving the safety of young drivers. They may also inform future enforcement and education policies for novice drivers. For example, rehabilitative interventions should occur coupled with enforcement soon after citation. Visible display of GDLS status would assist their identification.
