開門殺

開門殺是指機動車上的乘客或司機打開車門後，從機動車旁邊駛過的自行車、電動自行車、摩托車撞上車門的事故，此時非機動車的駕駛員有可能會受傷或死亡^[1][2][3][4]。另外車門突然打開後，車輛一旁的騎手也有可能會為避免撞上車門緊急轉向而撞到了其他車輛、非機動車或者摔倒受傷。^[5][6]。如果汽車的車門是推拉門或鷗翼車門，那麼發生開門殺的概率幾乎為0。此外某車輛的車門打開後，該車輛一旁的機動車也有可能撞上車門，而正準備下車的機動車駕駛員或乘客有可能因此受傷。

一名自行車騎手途徑一輛汽車時，撞上了汽車打開的車門

為了避免開門時撞到人，司機或乘客在打開車門之前應該查看一下後視鏡或者觀察一下車輛周圍的情況，或者用遠離車門的那個手來開車門，這樣就能迫使自己查看車門周圍的情況。對於非機動車騎手來說，他們應該遠離停著的車輛，因為車輛停止後有人可能會開門下車^[7]。

Visibility problems due to visual obstruction i.e., from bodywork or pillars of the vehicle were not found to be a major factor in these accidents.

A typical dooring law requires that a person opening a vehicle door ensure that it is reasonably safe to open the door, that opening the door will not interfere with moving traffic, and that the door is not open for any more time than necessary.

One of the most common causes of bike crashing is a stopped motorist who suddenly opens a door into the path of an approaching rider.... The best way to prevent this is to avoid pedaling in the 「door zone」—the three- to five-foot area next to a parked car.
