Abstract

Introduction Speeding represents one of the main causes of road crashes worldwide, particularly among young drivers who are over-represented in road-crash statistics. For promoting road safety in France, an automatic speed enforcement (ASE) system was introduced late 2002. Objective In order to examine its efficiency on speeding and its motivations, we compared young drivers' intentions and beliefs about speeding between the introduction of ASE (T1) and its completion in 2005 (T2) via a large survey based on the extended Theory of Planned Behaviour (TPB). We assumed the introduction of the ASE would covariate with a reduction in intention to speeding between T1 and T2 and a change in the extended TPB factors according to gender and driving experience. Method One thousand one hundred and ninety-two young participants (49.7% men) divided into novice, beginner, and more-experienced drivers filled in a questionnaire based on the extended TPB about their driving behaviour and history at T1 and 24 months later (T2). Results Men, beginner and more-experienced drivers expressed more intention to speeding within the next 12 months at T1 and showed a higher decrease in intention between T1 and T2 as compared to women and novice drivers. The extended TPB accounted for 59% of the variance in the decrease of the intention to speeding. Its main predictors were: lower perceived behavioural control over speeding, less social pressure, lower perceived similarity with the prototypical deviant driver, and higher comparative optimism. Secondly, slightly more positive behavioural beliefs and more negative outcome evaluations predicted this decrease. Conclusion Practical implications of the findings for road safety are discussed.
