The Queensland Speeding Engagement Trial (QSET) experimentally tested the impact of a procedurally just policing letter sent to individuals detected speeding by mobile and fixed cameras. A total of 15,681 drivers received an infringement notice during the trial period. To reduce the likelihood of a Type I error, this study reports results for 5% of the sample (n = 835). Drivers in the control condition (n = 419) received a speeding infringement notice as per normal while those in the experimental condition (n = 416) received a procedurally just letter in addition to the speeding infringement notice. The experimental letter featured a picture of a roadside memorial with statements to demonstrate respect, neutral decision making, trustworthy motives, and public support needed to reduce the death toll on Queensland roads. Follow up administrative data indicated that the experimental intervention reduced subsequent speeding and all traffic offences for young drivers (18-24 years) who were considered high-range offenders when compared with the control condition. Additionally, all young drivers who received the procedurally just letter in addition to their infringement notice were less likely to have a non-speed related traffic offence in the six months after receiving their camera detected speed notice. This suggests that procedural justice can be delivered in a non face-to-face format and affect subsequent offending behaviour for certain populations.
