Reduced mobility during COVID-19 lockdowns means not only fewer vehicles at risk of collision, but also an opportunity to speed on empty streets. The objective of this paper is to examine the impact of the first wave of the pandemic and the first lockdown on motor vehicle collisions (MVCs) and associated injuries and deaths in Greece. Using monthly data at the regional unit level, I provide descriptive evidence and subsequently follow a difference-in-differences econometric approach, comparing trends in 2020 with those of the previous 5 years while controlling for unemployment and petrol prices. I found a steep decline in collisions, injuries and deaths compared with what would have been otherwise expected. In March and April 2020, there were about 1226 fewer collisions, 72 fewer deaths, 40 fewer serious injuries and 1426 fewer minor injuries compared with what would have been expected in the absence of the pandemic.
新冠疫情封锁期间出行减少，这不仅意味着发生碰撞风险的车辆减少，也意味着有机会在空荡荡的街道上超速行驶。本文的目的是研究希腊第一波疫情和首次封锁对机动车碰撞事故（MVC）以及相关伤亡情况的影响。利用区域单位层面的月度数据，我提供了描述性证据，随后采用双重差分计量经济学方法，在控制失业率和汽油价格的同时，将2020年的趋势与前5年的趋势进行比较。我发现，与预期情况相比，碰撞事故、伤亡人数都大幅下降。与没有疫情时的预期相比，2020年3月和4月，碰撞事故减少了约1226起，死亡人数减少了72人，重伤人数减少了40人，轻伤人数减少了1426人。
