What is the speed limit for small cars on highways?

[SanLawson]

Highway speed limit for small cars is 120 kilometers per hour. When driving normally on highways, the minimum speed for motor vehicles should not be lower than 60 km/h. Small passenger vehicles must not exceed 120 km/h at maximum speed, while large buses and trucks must not exceed 90 km/h, and motorcycles must not exceed 80 km/h and are prohibited from carrying passengers. When the speed displayed on traffic signs or road signs differs from the above regulations, the signs or markings should be followed. Highways are multi-lane roads exclusively designed for directional and lane-separated vehicle traffic with full access control. The annual average daily traffic volume for highway design should exceed 15,000 passenger car equivalents, with a design speed ranging from 80 to 120 kilometers per hour.

I've been driving on highways for over a decade. The speed limit for passenger cars is usually 120 km/h, which applies to most national highway sections. But it varies by location: in mountainous areas or near cities, the limit might drop to 100 or 80 km/h, or even lower—so always watch for road signs. Speed limits aren't there to annoy you; safety comes first—higher speeds mean longer braking distances, especially on wet or icy roads where losing traction can be dangerous. I've seen many accidents caused by speeding, and the fines are real: exceeding the limit by 10% costs you 3 points and a 200 RMB penalty. I also recommend regularly checking tire wear and brake systems—keeping your car in good shape helps prevent accidents.

Hi, I usually commute on highways where the speed limit for cars is generally 120 km/h, but don't think it's a rigid rule: for example, you need to slow down to 80 when entering tunnels, and there are speed cameras near toll stations. I find navigation apps very helpful as they provide real-time speed limit alerts, helping avoid speeding tickets. Driving requires flexible speed adjustment, especially in heavy traffic—don't rush to change lanes; maintaining around 110 km/h is fuel-efficient and safe. Occasionally on business trips, I've noticed slight speed limit variations between provinces—for example, highways in western regions might cap at 100 km/h, so checking maps beforehand is wise.

As an ordinary person who enjoys delving into automotive technology, I know that the speed limit for high-speed sedans is generally set at 120 kilometers per hour, based on road engineering and safety calculations. Modern vehicles' GPS systems automatically warn of speeding, and some cars even come with adaptive cruise control to assist in maintaining speed. Setting the limit too high would increase fuel consumption and wear; the 120 km/h balance point makes driving more efficient. In special road conditions like bridges or slopes, the speed limit may be reduced to below 100 km/h to prevent risks. In short, reasonable speed reduction benefits both others and oneself.

I believe obeying traffic rules is fundamental. The speed limit of 120 km/h for sedans on highways is legally mandated. Exceeding this limit will be captured by speed cameras, resulting in a 200 yuan fine and penalty points for minor violations, or even causing accidents in severe cases. Different road sections like mountainous highways or urban ring roads often have specific speed limits, such as 100 km/h warning signs that must be heeded. While driving, I also maintain safe distances and avoid hazards like drunk or fatigued driving. Speed limits aren't just numbers—they're directly related to overall traffic safety.
