Risky driving behaviours such as mobile phone use and speeding remain common among young people, thereby contributing to their over-representation in road crashes. There is much evidence that similar-aged peer passengers can have a negative impact on a young driver’s behaviour; however, there is also research that supports the positive influence that peer passengers can have when they speak up about risky behaviours. Road safety education programs, such as the Royal Automobile Club of Queensland’s (RACQ) Docudrama program, aim to help young people understand the important role they play as peer passengers and, thus, the importance of being willing to speak up to a driver who may be engaging in risky behaviours. Extending on a previous evaluation of the RACQ Docudrama program, the current study uses an Extended Theory of Planned Behaviour framework to evaluate the program’s effectiveness in influencing peer passengers’ intentions and self-reported behaviour in speaking up against risky driving behaviours, including mobile phone use and speeding. A repeated-measures design compared participants’ responses over 3 time-points: Time 1 (one month before participating in the program), Time 2 (immediately after having participated in the program), and Time 3 (three months after program participation). The results indicate that levels of anticipated regret for having not spoken up were higher following participation in the program suggesting that it encouraged young people to consider how they would feel if something was to happen and they, as passengers, had not tried to prevent it by speaking up. Three months after participating in the program, the majority of participants reported that they were positively influenced by the program in terms of engaging in safer behaviours as passengers; although the significant effects regarding improvements were observed only immediately after participating in the program. The implications of such findings are discussed in terms of the need for some type of ‘booster’ post-program participation to capitalise on the positive immediate effects that the program evokes.

危险的驾驶行为（例如使用手机和超速驾驶）在年轻人中仍然很常见，从而导致他们在交通事故中的比例过高。有许多证据表明，同龄同龄乘客可能会对年轻驾驶员的行为产生负面影响。但是，也有研究支持同行乘客在谈论危险行为时可以产生的积极影响。道路安全教育计划，例如昆士兰皇家汽车俱乐部（RACQ）的Docudrama计划，旨在帮助年轻人理解他们在同伴乘客中扮演的重要角色，因此，愿意与可能会说服驾驶员的人说话的重要性从事冒险行为。扩展了先前对RACQ Docudrama程序的评估，当前的研究使用计划行为的扩展理论框架来评估该计划在影响对等乘客的意图和自我报告的行为以反对危险驾驶行为（包括使用手机和超速驾驶）时的有效性。重复测量设计比较了参与者在3个时间点上的反应：时间1（参加计划前一个月），时间2（参加计划后立即）和时间3（计划参加后三个月）。结果表明，参与该计划后，人们对未说出话感到遗憾的程度更高，这表明它鼓励年轻人考虑如果事情要发生，他们的感受，而作为乘客，他们并未试图通过阻止这种行为来防止这种情况的发生。讲起来。参加该计划三个月后，大多数参与者报告说，他们在乘坐乘客时采取更安全的行为方面受到了该计划的积极影响。尽管只有在参与该计划后，才能立即观察到与改进有关的重大影响。讨论了这些发现的含义，涉及需要某种类型的“推动者”参与计划后，以利用该计划所带来的积极直接影响。
