What is the speed limit for vehicles according to national standards?

[AmaraFitz]

Highways should indicate the speed limits for lanes, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour. Reasons for speed limits: Why are there maximum and minimum speed limits for motor vehicles on highways? This is primarily based on the design speed of the highway. Statistics on highway traffic accidents show that speeding is one of the main causes of traffic accidents, accounting for about 55% of all traffic accidents. Speed regulations on other roads: According to regulations, motor vehicles must not exceed the speed indicated by speed limit signs or markings on the road. On roads without speed limit signs or markings, motor vehicles must not exceed the following maximum speeds: (1) On roads without a central dividing line, the speed limit is 30 kilometers per hour in urban areas and 40 kilometers per hour on highways; (2) On roads with only one lane in the same direction, the speed limit is 50 kilometers per hour in urban areas and 70 kilometers per hour on highways. When driving on the road, strictly adhere to the regulations and avoid speeding.

I usually commute by riding an electric bicycle, with the maximum speed capped at 25 kilometers per hour as per national mandatory regulations, primarily for safety reasons. Speeds exceeding 30 kilometers per hour can easily lead to accidents or collisions, especially in crowded urban areas with heavy traffic. I once tried accelerating too quickly and almost had an accident because I couldn't brake in time. New bikes come with speed limiters that trigger alarms or force deceleration if the speed is exceeded. They also must be equipped with pedals so you can still ride manually if the battery runs out. Although adhering to this speed limit might feel slow, I've grown accustomed to it and find it more reassuring, plus it reduces maintenance efforts. Occasionally, I hear people complain about the speed being too slow, but I believe safety comes first—seeing numerous traffic accidents on the road makes me realize how necessary this standard is. Regularly checking tire pressure and brakes can also help maintain a steadier speed.

I do some small car repair jobs, and need to know that the national standard for electric bicycles limits the speed to 25 km/h at most. There's a small chip designed to control the motor output, and with stable battery power supply, the output must comply with the standard. Higher speeds consume more power and are dangerous, and speeding can result in fines ranging from tens to hundreds of yuan, with the vehicle's license being revoked. Repair shops often encounter modified bikes where the speed limiter is removed to exceed 40 km/h, but burning out the circuit can render the bike completely useless, costing even more. It's advised not to tamper with it—the factory settings are the most durable. Electric bicycles are moderately fast, making commutes easier, but for long distances, it's better to switch to a proper motorcycle that can go over 60 km/h for real fun. Maintain the battery well and replace the controller periodically to keep it in safe condition.

Riding an electric bike to commute is common, with the national standard setting a speed limit of 25 kilometers per hour. After riding for a few months, I feel this speed is just right on crowded streets, making it less stressful. Going just a bit faster would exceed the limit, and police occasionally check, with fines reaching up to two hundred yuan. I had a fall once when there was no speed limit, as I couldn't turn in time at higher speeds. Nowadays, new models sold at bike shops come with voice alerts that beep when exceeding 20 km/h. It can feel a bit slow when in a hurry, but safety comes first, especially on slippery roads during rainy days—driving slower is steadier. It's suitable for short commutes, but for longer distances, taking the bus or a taxi is necessary. You get used to it, and electric bikes also tend to have a longer lifespan.

New riders of electric bikes need to understand speed regulations. National standard vehicles are limited to within 25km/h. When I first started, I didn't know and accelerated to 30km/h, only to be reminded by a friend that it was a violation and could result in fines. The speed is designed this way to prevent accidents, especially in situations with many students riding or delivery personnel. The bike must have a pedal function as a backup power source, and the speed limit is factory-set. Speeding can easily cause battery overheating and affect the range. This speed is sufficient for urban areas, but exceeding it in suburban areas may lead to fines and penalty points. Learning to ride safely is most important. It may feel slow at first, but after getting used to it, it becomes much more worry-free. Regularly check the handlebars and controller.

Speaking of the national speed standard, there's deep thought behind the 25km/h limit for electric bicycles. The Traffic Safety Law states this speed can reduce accident rates by 70%, fitting perfectly into urban traffic flow during congestion. From my observations, lower speeds also mean less air pollution and reduced noise. Regulations encourage adopting this standard to replace older, faster models, with government subsidies for purchasing new compliant vehicles. Community neighbors all comply, and the penalty system has decreased violations by 20%. In the long run, it enhances public safety and fosters healthy slow-riding habits. Repair shops also find it easier, with common issues being battery aging affecting speed limiters.
