驶出 is a compound verb meaning 'to exit (a place) by vehicle'. It combines 驶 (shǐ), which means 'to drive' or 'to operate a vehicle', and 出 (chū), meaning 'to go out' or 'to exit'. Together, they emphasize the action of a vehicle moving out from an enclosed or defined location—such as a tunnel, garage, parking lot, highway exit ramp, or dock. Unlike generic verbs like 离开 (to leave), 驶出 specifically implies vehicular motion and is commonly used in transportation contexts, traffic reports, navigation instructions, and formal descriptions of movement.

This verb typically follows a subject (often a vehicle or driver) and may take a directional complement or location phrase marked by 从…（中）or onto a noun phrase with 的. It is neutral in register—used in both spoken and written Chinese—but rarely appears without a clear spatial reference point. It does not apply to pedestrians or non-vehicle movement; for those, use 走出 or 离开 instead.
