Specific deterrence is the actual experience of being sanctioned for the speeding behaviour. This may be an immediate sanction in the form of being stopped by a police officer and issued an infringement notice, or receiving an infringement later if detected by a speed camera. Research suggests that complex behaviours are not deterred by highly visible enforcement, but through the actual experience of detection. Other complex behaviours include unsafe overtaking or lane changes, which are driver behaviours that are momentary and involve complicated thought processes and may be performed during a journey.
