Objectives

In order to examine its efficiency on speeding and its motivations, young drivers’ intentions and beliefs about speeding before the introduction of automatic speed enforcement and its completion.

Methodology

A large survey based on the extended Theory of Planned Behaviour (TPB)

Key Findings:       

  • 1,192 young participants (49.7 per cent men) were divided into novice, beginner and more experienced drivers and filled in a questionnaire about their driving behaviour before speed cameras were installed and 24 months later.

  • Men, beginner and more experienced drivers expressed more intention to speeding within the next 12 months before the camera installation and showed a higher decrease in intentions afterwards, compared to women and novice drivers.

  • The extended TPB accounted for 59 per cent 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 drivers; and higher comparative optimism. Slightly more positive behavioural beliefs and more negative outcome evaluations also predicted this decrease.

  • In order for a behavioural change to be effective, an attitudinal change in favour of the target behaviour may be required. Campaigns and trainings should both teach young drivers, who lack experience, that complying with the speed limit is really in their own benefit because transgressing the speed limits increases the probability of negative consequences arriving to them.
