What are the speed limits for four lanes in the same direction?

[VanMorgan]

On highways with four lanes in the same direction, the maximum speed should not exceed 120 km/h. Here are the relevant details: 1. According to Article 78 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": Highways should indicate the speed limits for each lane, with the maximum speed not exceeding 120 km/h and the minimum speed not less than 60 km/h. 2. For two lanes in the same direction: The minimum speed for the left lane is 100 km/h. For three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 km/h, and the minimum speed for the middle lane(s) is 90 km/h. If the speed limit indicated by road signs differs from the above lane speed regulations, drivers should follow the speed limit indicated by the road signs.

When I was driving on the highway once, the speed arrangement for the four lanes was as follows: the leftmost lane is usually the overtaking lane, where the speed can be maintained at 120 kilometers per hour, but avoid occupying it for too long; the middle two lanes are the main driving lanes, with speeds generally between 100 and 110 kilometers per hour, where maintaining a safe distance is key; the rightmost lane is the slow lane or exit lane, with speeds around 80 to 100 kilometers per hour, suitable for trucks or cautious driving. Remember to use only the left lane for overtaking, otherwise accidents can easily occur. I noticed that during holidays, the overall speed slows down, especially when encountering traffic jams or rainy weather. Maintaining a safe distance and paying attention to road signs can help avoid rear-end collisions.

I understand the traffic rules, where the four lanes in the same direction have different speed limits: the left lane has a speed limit of 120 km/h, mainly used for overtaking; the middle two lanes have speed limits of 100-110 km/h, intended for normal driving; the right lane has a speed limit of 80-100 km/h, suitable for slower vehicles. In actual driving, avoid speeding or occupying the left lane for too long, as violations will result in penalty points. Wind speed affects safety—reducing speed by 10% on windy days is more prudent. Observe surrounding traffic to avoid sudden lane changes.

Having driven countless miles, actual speeds depend on the lane: the far-left fast lane often reaches 120 or higher, but after overtaking, return to the middle lane; the middle lane is comfortable at 100-110; the right slow lane is safe at 80-90. Experience shows that speeds are higher with fewer cars in the early morning, but slower during the afternoon rush hour. Adjust the rearview mirror to monitor blind spots.

As a driver, I pay attention to the vehicle condition: SUVs maintain a steady 110 in the middle lane; sports cars can go 120+ in the left lane; compact cars stay in the right lane at 80-100. Battery failure or tire wear may reduce speed, so regular maintenance is recommended. Reduce speed by 10% in rainy weather to ensure clear visibility. When traffic is light, speed is flexible.

After years of commuting by car, I've observed that speeds in the four-lane highway often vary: the left lane is the fastest at 120 km/h, ideal for efficiency; the middle lane maintains a steady 100-110 km/h; while the right lane at 80-100 km/h is more fuel-efficient. During peak hours, all lanes slow down, and eco-driving is best practiced by using the right lane for slower speeds. Always check real-time traffic on navigation apps to avoid unexpected situations. Be aware that in dim lighting, it's easy to misjudge a car's speed based on its lights.
