To analyse the effect of the threat of disqualification.


A postal survey of 1100 drivers followed by qualitative study of a sample of those responding and two focus groups.

Key Findings

  • The threat of disqualification from driving is effective.

  • Not all drivers with penalty points perceive themselves as dangerous.

  • The risk of detection acts as a deterrent.

  • Drivers with penalty points are more likely to be male, aged between 35 and 64, have high annual mileages and drive for work
