Cultural Notes (if applicable)

In China, 车速 is often seen or heard in traffic-related situations. For example, road signs, navigation apps, and driving safety messages may remind drivers to 控制车速, meaning “control your vehicle speed,” or 降低车速, meaning “reduce your speed.”

Chinese traffic signs and driving instructions often use concise, formal wording. Because of this, 车速 may sound slightly more official than simply saying 开得快, which means “drive fast” in everyday speech.

A useful related phrase is 限速, meaning “speed limit.” For example, 限速六十公里 means “speed limit: 60 kilometers per hour.”

Conclusion

车速 means “vehicle speed” or “driving speed.” Remember that 车 means “vehicle” and 速 means “speed.” This word is especially useful when talking about driving, traffic safety, speed limits, and road conditions.
