'坐车' literally means 'to sit + vehicle', and functions as a verb meaning 'to ride a vehicle'—typically public or private motorized transport like buses, taxis, subways, or cars. It emphasizes the act of being a passenger rather than driving. Unlike '开车' (to drive), '坐车' always implies riding as a non-driver. The character 坐 conveys the posture of sitting, while 车 refers broadly to wheeled vehicles, not just automobiles but also trains and trams in colloquial usage.

This phrase is common in daily conversation for describing commutes, travel plans, or transportation choices. It’s neutral in register—used by children and adults alike—and often appears in questions ('你今天怎么坐车去学校？') or statements about routine ('我每天坐车上班'). It does not apply to bicycles, motorcycles (where riders '骑车'), or walking—those require different verbs. '坐车' can stand alone or combine with directional complements (e.g., '坐车去北京') or duration/quantity phrases (e.g., '坐车十分钟').
