Summary
This review paper addresses the persistent public health issue of high crash rates among young novice drivers, despite decades of research into risk factors. The authors aim to synthesize evidence from the last decade (2007–2017) to identify the strongest indicators of crash risk compared to experienced drivers and to evaluate effective preventive interventions. The study is motivated by the need for a holistic understanding of how individual, social, and environmental factors interact, rather than examining them in isolation. The authors conducted a systematic review of 196 eligible papers, including empirical studies, systematic reviews, and crash reports, sourced from databases like PubMed and PsycInfo. The analysis adopts Bronfenbrenner’s ecological systems theory to categorize factors into individual characteristics, the social micro-system (parents, peers, training), and the broader socio-cultural macro-system. This framework allows for the examination of synergies between these domains, such as how social influences moderate individual cognitive deficits. Key findings indicate that the incomplete maturation of cognitive skills—specifically visual scanning, hazard anticipation, and inhibition of distractions—combined with high susceptibility to social influences, are the primary determinants of risk for young drivers. Young novices tend to scan roads more narrowly, underestimate risks, and overestimate their skills compared to experienced drivers. Personality traits like sensation-seeking and emotional states also contribute to risky behaviors, though their impact varies by context. Regarding interventions, the review finds that Graduate Driver Licensing (GDL) systems significantly reduce fatal crashes. Furthermore, cognitive training focusing on hazard perception is more effective than vehicle-handling training. Behavioral interventions, such as peer-led campaigns and brief educational programs, show modest but significant improvements in attitudes and specific behaviors like seat belt use and reduced drink-driving. The significance of this work lies in its demonstration that young driver risk is multifaceted and developmental. The authors conclude that effective interventions must adopt an ecological approach, addressing not just individual skills but also the social and environmental contexts in which young drivers operate. They highlight gaps in current knowledge, particularly the lack of long-term follow-up data on training effectiveness, and call for more robust, holistic programs that leverage positive social experiences and technological advancements to mitigate crash risks.
