Penalties for speeding and their effect on moving violations: Evidence from Quebec drivers
研究2008年魁北克省大幅提高超速罚款并实施现场吊销驾照后，驾驶者违章行为的变化，发现新法有效遏制超速，尤其对男性、年轻人和高扣分驾驶者效果更明显。
Abstract In 2008, the province of Quebec drastically increased penalties for speeding well above the speed limit by doubling fines and instituting on‐the‐spot licence suspension. Using administrative driving and licensing records in Quebec from 2006 to 2010, we examine whether the new law discouraged unlawful driving behaviour by investigating the frequency with which motorists received traffic citations. We find that the new law was effective in deterring motorists from speeding. Moreover, the effect was most pronounced for males compared with females, for young compared with old, and especially so for drivers with high demerit point balances accumulated from past infractions compared with those with few or no tickets. In sum, the change in behaviour was most apparent for those drivers who were the intended targets for the legislation.
