驾车 is a formal separable verb (离合词) meaning 'to drive a vehicle.' It is commonly used in written or official contexts such as traffic regulations (e.g., 酒后驾车 'drunk driving'). Unlike the everyday word 开车, 驾车 appears more in legal or administrative language. As a separable verb, 驾 and 车 can be split by aspect markers or modifiers: e.g., 驾过车 ('have driven a car'), 驾着车 ('is driving'). One example below shows the separated form.
