Truck speed limits are capped at 80 km/h, with a minimum speed not lower than 60 km/h. Below are the legal bases for truck speed limits: Highway speed regulations: Highways must indicate the driving speed for each lane. The maximum speed must not exceed 120 km/h, and the minimum speed must not be lower than 60 km/h. On highways, the maximum speed for small passenger vehicles must not exceed 120 km/h, other motor vehicles must not exceed 100 km/h, and motorcycles must not exceed 80 km/h. Speed regulations for different lanes: For roads with two lanes in the same direction, the minimum speed for the left lane is 100 km/h. For roads with 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 is 90 km/h.

I often drive heavy trucks for long distances on highways, where the speed limit for trucks is generally 80 kilometers per hour, not 90. This is mainly for safety reasons, as trucks are heavy and have long braking distances. If driven above 90 km/h, they are more likely to lose control and overturn in emergency situations. In bad weather, the speed must be further reduced. For example, when the road is wet on rainy days, the speed limit should be lowered to below 60 km/h; otherwise, the risk of skidding is high. Additionally, speed cameras on highways are very dense, and even a slight overspeed can be caught, resulting in a 200 yuan fine and 6 penalty points. I've seen too many drivers get into accidents due to speeding, so I recommend everyone develop the habit of regularly checking speed limit signs. In-car navigation can also remind you of the real-time speed limit on the current road section. For long-distance driving, setting the cruise control at 75-80 km/h is both fuel-efficient and smooth.

As a driver who has operated trucks for several years, I recall that the speed limit on highways is uniformly set at 80 kilometers per hour for trucks. This differs from passenger cars, which can reach 120 km/h on certain sections. Due to their large size and strong inertia, trucks maintain stability at 80 km/h. Once, while hauling a heavy load, I slightly accelerated to 85 km/h and immediately felt the steering wheel shake, prompting me to slow down promptly. Electronic surveillance cameras are also prevalent, with strict enforcement against speeding. The speed limit accounts for fatigue driving risks, as higher speeds increase drowsiness. It's advisable to adhere to rest area regulations, taking a break every two hours. Highway service areas prominently display signs reminding truck drivers to stay below 80 km/h.

I think the speed limit for trucks on highways is scientifically set at 80 kilometers per hour. This isn't arbitrarily determined; traffic authorities base it on extensive accident data to ensure safe passage even on curves or slopes. Exceeding the speed limit results in hefty fines and possibly even license suspension. I recommend using the speed limit alert function more often while driving, as new vehicles come equipped with GPS reminders. Speed limits adjust under different weather conditions, dropping below 60 in foggy weather. Familiarity with highway rules can prevent 80% of accidents, and cultivating good driving habits is more important than anything else.

How to Deal with Tire Pressure Warning?

The following are the methods to eliminate tire pressure warning and the functions of the tire pressure monitoring alarm. 1. How to eliminate the tire pressure warning in car tires: ① After the tire pressure indicator light comes on, pull the car over to the side; ② After confirming that the wheels are abnormal, we must check whether the tire pressure is high or low. If the alarm is triggered due to excessive tire pressure, we can slightly increase the tire gas to the safe value of tire pressure. If the tire pressure is shown to be too low, it needs to be reset before driving for a certain distance. 2. The functions of the tire pressure monitoring alarm: ① Prevent tire blowouts: Real-time monitoring of tire pressure and temperature to prevent problems before they occur. ② Save fuel: Maintaining the correct tire pressure reduces car fuel consumption. ③ Reduce wear: Insufficient tire pressure can cause excessive wear (tire scrubbing) and shorten the service life of the tires.

How to Determine if the Mercedes-Benz Charcoal Canister Solenoid Valve is Faulty?

Methods to determine if the Mercedes-Benz charcoal canister solenoid valve is faulty are as follows: Abnormal fuel tank usage: The fuel pump nozzle shuts off prematurely during refueling, or gas is released when opening the fuel tank cap. Fuel dripping: Presence of gasoline vapor or fuel droplets at the charcoal canister's outlet. Power loss: Weak acceleration, jerking movements, unstable idle speed fluctuating between high and low; engine stalling and failure to start, unusual noises while driving. The main function of the charcoal canister is to adsorb and filter gasoline vapor inside the fuel tank. The solenoid valve controls the entry of fuel vapor into the engine for combustion, thereby reducing fuel consumption and preventing excessive pressure in the fuel tank.

Does ECVT have a steel belt?

ECVT is a type of continuously variable transmission, and structurally, it also has a steel belt. Here is some relevant information about ECVT: Definition: ECVT is a hybrid transmission integrated with an electric motor. The ECVT transmission is specifically developed for new energy vehicles and hybrid models. ECVT achieves a balance between engine power and motor power by using a gear and two motors (one large and one small). Therefore, the car's engine does not directly drive the vehicle but instead relies on these two motors for power output. Combination Method: ECVT changes the combination of planetary gears to control the motor's speed, thereby adjusting the motor's power and torque. The motor, which plays a crucial role in this process, ensures that both the speed change and torque change are linear. Hence, as long as the power and torque of the engine and motor are well-coordinated, achieving smoothness similar to CVT is not a problem.

Is 5w30 or 5w40 better for the Hyundai Elantra?

The owner's manual for the Hyundai Elantra recommends using either 5W-20 or 5W-30 as the dedicated engine oil, so 5W30 is the appropriate choice. Engine oils are classified into different grades because engine models and operating conditions vary, leading to different lubrication requirements. Related information: Oil grade: 5w30 represents the oil grade, where the number before the W indicates the minimum operating temperature the oil can withstand. For example, 5W can endure temperatures as low as -30°C. W grades include 0W, 5W, 10W, 15W, etc., with smaller numbers indicating better low-temperature fluidity and performance in cold conditions. The number after the W represents the oil's viscosity at 100°C, with grades such as SAE20, 30, 40, etc. Higher numbers indicate higher viscosity. Oil performance: Most vehicles today use multi-grade oils, which contain special additives that allow the oil to flow easily in cold temperatures without solidifying, while maintaining appropriate viscosity and good lubrication performance in high-temperature conditions.
