如果你无所谓口语化的话,这句就可以:Drunk driving is a common cause of accidents.
按照英文正式的说法醉驾叫做 Driving under the influence of alcohol。法律常用语中叫做Driving under the influence (DUI),也就是“在影响下驾驶”,原因是西方法律中DUI还包括毒驾。所以DUI是统称,需要标注什么原因的时候加上 of ___(原因)____ 就可以了。所以正式的翻译是:Driving under the influence of alcohol is a common cause of accidents.
Drunk driving is a common cause of accidents,
醉驾是发生事故的常见原因
