What is the maximum speed limit for trucks on highways?

[DiFaith]

On highways, the maximum speed limit for trucks must not exceed 100 kilometers per hour. Highway speed limit regulations: 1. Minimum speed: When driving normally on highways, the minimum speed for motor vehicles must not be lower than 60 km/h. 2. Two lanes in the same direction: The minimum speed for the left lane is 100 km/h. 3. Three or more lanes in the same direction: The minimum speed for the far-left lane is 110 km/h, while the middle lane has a minimum speed of 90 km/h. 4. Small passenger vehicles: The maximum speed limit for small passenger vehicles on highways must not exceed 120 km/h, while other motor vehicles must not exceed 100 km/h, and motorcycles must not exceed 80 km/h.

The maximum speed limit for trucks on highways is 90 km/h, as stipulated by national regulations. As a long-haul truck driver myself, based on personal experience, it's crucial to strictly adhere to the speed limit on the road. Otherwise, fines are the least concern—accidents can be life-threatening. Once, I tried to speed up to meet a delivery deadline and almost rear-ended another vehicle, with my tires even smoking. Trucks are inherently heavy, with longer braking distances, and high winds can make them unstable at speed. The 90 km/h limit is well-justified. Now, I always check speed-limited zones on the map before departure and remind myself that driving slower is safer. I advise fellow drivers to maintain their tires and braking systems regularly. It's not worth risking points on your license for speeding—safety should always come first.

From a technical perspective, highway speed limits are determined based on the characteristics of commercial vehicles. Having studied automotive engineering for a long time, I can confirm that the maximum speed limit for standard trucks is 90 km/h, primarily due to the risk of brake failure caused by vehicle weight. Under heavy loads, braking distances can increase several fold when exceeding 100 km/h, and engine overload can easily lead to overheating. Traffic regulations clearly define tiered limits: 120 km/h for passenger cars, 100 km/h for buses, and 90 km/h for trucks. When inspecting vehicles, I often remind owners that speeding not only violates traffic laws but also accelerates wear on chassis and suspension components. In actual driving, speed should be fine-tuned according to load - light loads may approach 90 km/h, while heavy loads are best kept below 80 km/h. Developing good habits like using GPS speed alerts helps prevent unintentional acceleration and loss of control.

As a young and new truck owner delivering goods, I was also curious about speed limits. On highways, trucks are only allowed to go up to 90 kilometers per hour. At first, I thought it was too slow and wanted to drive faster, but I got pulled over by the police once and fined. Later, I understood: the truck is too heavy, and it really can't stop quickly at high speeds. Now, I use my phone's navigation to set speed limit reminders to avoid speeding. By the way, driving steadily also saves fuel—I calculated it can reduce fuel costs by about 10%. For new drivers who are confused, I recommend making more short trips to get familiar with the rhythm and not driving recklessly in foggy or rainy weather.
