P plates (or decals) identify a driver's license status to other road users. They are a compulsory part of the graduated driver licensing system in Queensland, Australia, for drivers on a P1 (provisional 1) or P2 (provisional 2) license. This study explored the perceptions of young drivers regarding the display of P plates (decals) in Queensland, Australia.
In this study, 226 young drivers with a provisional (intermediate/restricted) license completed a 30-min online survey between October 2013 and June 2014. t Tests were used to compare the opinions of people who displayed their plates nearly always with those who displayed them less frequently.
Participants approved of the requirement to display P plates with 69% of those on a P1 license and 79% on a P2 license supporting the condition to display P1 (red) plates. Participants on a P1 license (62%) and a P2 license (68%) also approved the requirement to display P2 (green) plates. However, young drivers also perceived that the display of P plates (measured from 1 = never to 5 = nearly all the time) enabled newly licensed drivers to be targeted by police and other drivers (those who do not always display P plates: M = 3.72, SD = 0.94; those who nearly always display P plates: M = 3.43, SD = 1.09).
The study findings suggest that participants who nearly always display their P plates are more likely to report that having to display their plates resulted in them driving more carefully.
P牌（或贴纸）向其他道路使用者表明驾驶员的执照状态。在澳大利亚昆士兰州的分级驾驶员执照制度中，P牌是持有P1（临时1级）或P2（临时2级）执照的驾驶员的强制要求。本研究探讨了澳大利亚昆士兰州年轻驾驶员对展示P牌（贴纸）的看法。
在本研究中，226名持有临时（中级/受限）执照的年轻驾驶员于2013年10月至2014年6月期间完成了一项30分钟的在线调查。使用t检验比较几乎总是展示车牌的人与较少展示车牌的人的意见。
参与者赞成展示P牌的要求，69%的P1执照持有者和79%的P2执照持有者支持展示P1（红色）牌的规定。P1执照持有者（62%）和P2执照持有者（68%）也赞成展示P2（绿色）牌的要求。然而，年轻驾驶员也认为展示P牌（从1 = 从不展示到5 = 几乎一直展示进行衡量）会使新获得执照的驾驶员成为警察和其他驾驶员（那些不总是展示P牌的人：M = 3.72，标准差 = 0.94；那些几乎总是展示P牌的人：M = 3.43，标准差 = 1.09）的目标。
研究结果表明，几乎总是展示P牌的参与者更有可能报告称，必须展示车牌使他们开车更加谨慎。
