What is the maximum speed limit for passenger cars on highways in kilometers per hour?

According to the relevant regulations of the Road Traffic Safety Law, highways should indicate the speed limits for each lane. The maximum speed must not exceed 120 kilometers per hour, and the minimum speed must not be lower than 60 kilometers per hour. On highways, the maximum speed for small passenger cars must not exceed 120 kilometers per hour, while other motor vehicles must not exceed 100 kilometers per hour, and motorcycles must not exceed 80 kilometers per hour. As stipulated in the "Road Traffic Safety Law Implementation Regulations," if there are two lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour. If there are three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 kilometers per hour, and the minimum speed for the middle lane is 90 kilometers per hour. If the speed limit indicated by road signs conflicts with the above lane speed regulations, drivers must follow the speed limit indicated by the road signs. Highway driving precautions: Pedestrians, non-motor vehicles, tractors, agricultural vehicles, electric bicycles, wheeled special machinery, full-trailer tractors, and motor vehicles with a designed maximum speed below 70 kilometers per hour are not allowed to enter highways. Additionally, drivers with a learner's permit are not allowed to drive on highways. Vehicles entering highways must be equipped with a warning sign for breakdowns. After entering the highway, motor vehicles should accelerate to at least 60 kilometers per hour as soon as possible. Vehicles entering the highway from an on-ramp must increase their speed in the acceleration lane and turn on the left turn signal. When merging into the traffic lane, they must not obstruct the normal flow of other vehicles.
From my over ten years of driving experience, the speed limit for passenger cars on highways is usually no more than 120 kilometers per hour. This regulation isn't arbitrary—highway design and traffic laws take safety factors into account. While speeding can be thrilling, the braking distance at 130 km/h is over 30% longer than at 120 km/h, making it much harder to stop in an emergency. I once nearly had an accident during heavy rain because I didn't control my speed. At high speeds, wind resistance increases, and fuel consumption rises too; maintaining a cruising speed around 115 km/h is the most fuel-efficient and stress-free. In mountainous areas or sections with many curves, the speed limit might drop to 100 km/h—always check road signs rather than guessing. With more speed cameras being installed, fines can range from 1,000 to 2,000 yuan plus demerit points, with up to 12 points leading to license suspension—hardly worth the risk. Safety comes first when driving, especially on long trips; take a break every two hours at rest stops to combat fatigue. Remember, driving slower often means arriving earlier because you avoid trouble along the way. For those who've just gotten their license, I recommend driving on the highway a few times with an experienced driver to gain some practical experience.
As a car enthusiast who cherishes my vehicle, I have a profound understanding of automotive performance. The 120 km/h speed limit on highways is scientifically justified, as it aligns with the braking systems and tire grip of most compact cars. At 120 km/h, the suspension can stably handle curves and road undulations, with risks increasing significantly beyond this speed. High-speed driving generates excessive wind noise that compromises comfort and can lead to engine overheating and soaring fuel consumption. Safety test data indicates that for every 10 km/h increase in speed, braking distance grows by 40% – a primary cause of highway rear-end collisions. During long-distance drives, I always use cruise control to maintain 110-120 km/h for relaxed and stable operation. While ordinary sedans can technically reach 200 km/h, real-world highway conditions don't support such speeds. I recall driving 150 km/h on Germany's unlimited-speed autobahns, but became much more cautious when returning to domestic highways. In rainy conditions with slippery roads, staying below 100 km/h is essential to prevent skidding. While performance modifications can boost horsepower, the penalties for speeding make it not worth the risk. The overall recommendation is to understand your vehicle's capabilities, respect speed limits, and avoid recklessly pushing boundaries. The best way to enjoy driving is within safe parameters.
