What is the speed limit on Wuma Expressway?

[Neil]

Expressway speed limits require a minimum speed of no less than 60 km/h and a maximum speed of no more than 120 km/h. According to Article 78 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": Expressways shall indicate the driving speed of lanes, with the maximum speed not exceeding 120 km/h and the minimum speed not less than 60 km/h. The following precautions should be taken when driving on expressways: 1. Safety check: Check for potential safety hazards before getting in the car. Before driving on the expressway, you should check whether the vehicle has any safety hazards. 2. Wear seat belts: Always wear seat belts on the expressway, including the driver, front passenger, and rear seats. Avoid placing unsecured items in the car. 3. Try to stay in one lane: Do not change lanes frequently on the expressway, switching between the overtaking lane and the driving lane. Never make sudden, unannounced deceleration or stops in the driving lane. While driving, do not drive side by side with other vehicles, do not drive in the overtaking lane for extended periods, and never attempt to overtake from the emergency stopping lane. Additionally, prepare for lane changes in advance when exiting the expressway to avoid missing the exit.

As a seasoned driver who frequently travels on the Wuma Expressway, I remember the speed limit is generally around 120 kilometers per hour. However, in certain special sections such as near city entrances or mountainous curves, the limit drops to 80 or 100, clearly marked on road signs. While driving, it's essential to frequently glance at the rearview mirror and watch for road signs—don't rely solely on navigation app alerts, as electronic devices can sometimes lag. Driving too fast increases the risk of losing control, especially during rain or at night when braking distances lengthen; a sharp turn could easily lead to a rollover. Adhering to speed limits not only saves fuel but also ensures safety. Last time I was fined several hundred yuan for exceeding the limit by 10 km/h—the money was minor, but the penalty points were more troublesome. Since then, I've been driving steadily and cautiously.

I think the speed limit on Wuma Expressway is mostly set at 120 km/h, which is based on safety considerations in road design, such as wide straight sections with good visibility, but it often drops to 100 km/h at exits or construction zones. Why is this speed set? Research shows that airflow can affect stability during overtaking, and tire grip decreases too quickly in rainy conditions. Speeding beyond 140 km/h doubles the collision force, making it hard for drivers to react in time. It's advisable to always observe the surroundings. The newly installed intelligent speed limit monitoring system is highly sensitive—getting caught exceeding the limit by more than 20% could result in a fine of over 1,000 yuan and 6 penalty points. Safety on the expressway is no trivial matter; it's better to leave early than to speed.

Those who have driven on the Wuma Highway know that the speed limit on the main road is basically 120 kilometers per hour, and there are often 80 warning signs at lane change points. These regulations are not made arbitrarily; they are based on engineers' tests of road friction coefficients and accident data analysis. Speeding not only causes fuel consumption to skyrocket but also means the airbag deployment speed can't keep up in a crash. It's wisest to slow down while driving, especially at night or in heavy fog. Remember, speed limit signs are life savers—don't mess with fines.
