‘疾驶’ is a compound verb meaning ‘to speed rapidly’ or ‘to dash forward at high speed’. The first character, 疾 (jí), means ‘swift’, ‘fast’, or ‘urgent’, and often conveys urgency or intensity — as in 疾病 (jíbìng, ‘illness’) or 疾风 (jífēng, ‘gale’). The second character, 驶 (shǐ), means ‘to drive’, ‘to sail’, or ‘to operate a vehicle’, and appears in words like 行驶 (xíngshǐ, ‘to travel/drive’) and 航驶 (hángshǐ, ‘to navigate’). Together, 疾驶 emphasizes rapid, purposeful motion — typically of vehicles (cars, trains, boats) or sometimes animals or natural forces like wind or rivers. It carries a vivid, slightly literary tone and is common in descriptive writing, news reports, and narrative prose.

This word implies controlled but urgent movement — not just speed for its own sake, but speed with direction and momentum. It’s rarely used for people walking or running; instead, it evokes images of a police car racing through traffic, a bullet train gliding along tracks, or a motorboat cutting across water. While grammatically a verb, 疾驶 usually functions as a predicate verb or as part of a verb phrase (e.g., 疾驶而来, ‘speeding toward us’).
