The speed limit of 120 kilometers per hour allows for a maximum overspeed of 50%, which is 180 kilometers per hour. Additional information: 1. Highways should indicate the speed limit for each lane, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour; 2. On highways, the maximum speed for small passenger vehicles should not exceed 120 kilometers per hour, while other motor vehicles should not exceed 100 kilometers per hour, and motorcycles should not exceed 80 kilometers per hour; 3. For roads with two lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour; for roads with three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 kilometers per hour, and the minimum speed for the middle lane is 90 kilometers per hour; 4. If the speed limit indicated by road signs differs from the above lane speed regulations, the speed limit indicated by the road signs should be followed.

When the speed limit is 120, I believe driving within 120 is the safest because road safety design is based on speed. Driving too fast extends the braking distance by several meters, making it extremely dangerous in case of sudden emergencies on the highway. With over a decade of driving experience, I once witnessed a speeding accident scene—cars destroyed and people injured, with no time for regrets. So, it's better to leave early rather than rush. Vehicle speedometers may have about a 3% error, so it's advisable to drive at 117-118 to leave some margin. Also, check tire wear; old tires have poorer grip and are more prone to skidding. Safe driving isn't just for yourself but also for passengers and others on the road. Arriving a bit slower makes for a more relaxed mood.

As an experienced driver, I usually drive around 125 km/h on roads with a 120 km/h speed limit. Sometimes when the road conditions are good, it feels okay to go a bit faster. However, I've actually tested the speedometer error - when it shows 125 km/h, the actual speed might already be 128 km/h. Getting caught by the police for speeding would be a huge loss. I've seen many friends receiving tickets with demerit points and fines starting from two to three hundred yuan. There are so many speed cameras on highways, it's best not to take the risk. Moreover, speeding increases fuel consumption - going from 120 to 130 km/h can cost over 20% more in fuel expenses. It's more worthwhile to save that money for a good meal. Driving steadily at 120 km/h actually makes the car more stable, with less engine noise, making long trips less tiring.

How to Read the Gauge on an Automotive Air Conditioning Pressure Meter?

The red indicator on an automotive air conditioning pressure meter represents the high-pressure side, while the blue one indicates the low-pressure side. The units for pressure values include kg/cm², MPa, kPa, and Psi. When the compressor is running, maintain the engine speed between 1500-2000 r/min and activate the air conditioning to engage the compressor. Typically, the low-pressure side should read around 150-250 kPa, and the high-pressure side should be approximately 1400-1600 kPa. Below is additional information regarding air conditioning system pressure: 1. The pressure in the air conditioning system is diagnosed using a manifold gauge set. The method involves connecting the high and low-pressure hoses of the gauge to the respective high and low-pressure service (charging) ports of the system. Set the air conditioning to the coldest setting and the blower speed to the highest. Enable recirculation mode, direct the airflow toward the face, and open all doors. 2. Operate the air conditioning system (ensure the engine maintains a steady speed, usually 1500 r/min, as using only idle speed may affect accurate fault diagnosis) and observe the gauge readings (for R12 or R-134a, normal operating pressures are: low-pressure side at 1.8–2.1 kgf/cm², high-pressure side at 12–14 kgf/cm² and 13–15 kgf/cm², respectively). If the readings fall outside these ranges, the air conditioning system is malfunctioning.

What does TRIP-A mean on a car?

TRIP-A refers to the short-distance mileage, also known as the trip mileage. TRIP is an English word meaning short-distance mileage. The function of TRIP-A is to help users calculate the kilometers traveled for each trip, and it can also be used to calculate fuel consumption based on the trip mileage. You can long-press the reset button to clear and reset it to zero. More details are as follows: 1. TRIP-A and TRIP-B odometers can be switched. To reset, press the small black button on the right for about one second. There are no restrictions on using TRIP-A and TRIP-B odometers. 2. TRIP-A can be set to reset to zero each time you refuel to calculate fuel consumption; TRIP-B can be set to reset to zero for each maintenance interval, such as every 5,000 KM. It can also be used to calculate the average fuel consumption over a certain period (several refuels). 3. The total odometer records and displays the vehicle's total mileage, which is the distance traveled since the vehicle was put into use. The total mileage of a car varies depending on the type of vehicle. 4. For common passenger cars like family sedans, the normal lifespan is 15~20 years, and under proper maintenance, it can last 300,000~500,000 kilometers. For common commercial vehicles like container trucks, the normal lifespan is 10~15 years, with a mileage of 400,000~800,000 kilometers.

Why is the car's one-button start not working?

Here are the reasons why the car's one-button start sometimes does not respond: 1. Check if the key is nearby, as the one-button start relies on key sensing. The car cannot start if the key is not present. 2. Verify if there was an operational error. If you only press the button without stepping on the brake, the car will power on, but the engine will not start. Another scenario is not holding the button long enough or not pressing it all the way down. 3. The gear is not in the P (Park) position. "Sensing issues": 1. Frequently placing the car key near electronic devices such as mobile phones, computers, or TVs may interfere with the low-intensity radio waves in the key. Alternatively, strong radio waves from nearby sources like TV towers, airports, or power plants can cause the one-button start to "fail." 2. The car key battery is low: If the remote control distance shortens or the sensing becomes less responsive, it indicates the car key battery is running low. In this state, the one-button start function will not work properly, and the battery should be replaced as soon as possible. 3. Car malfunction: In extreme cases such as fuel system issues, dead battery, or short circuits in electronic components, contact the 4S store staff directly.

Is a Four-Wheel Alignment Necessary After Changing Tires?

Generally, a four-wheel alignment is required after changing tires. The functions of four-wheel alignment for vehicles: 1. Significant benefits for tires: After a four-wheel alignment adjustment, the tires can maintain the optimal angle with the vehicle body, ensuring both improved grip and comfort. 2. Enhanced handling: After a four-wheel alignment adjustment, driving control can be correspondingly ensured. In emergency situations, sufficient tire grip allows the vehicle to follow the driver's intended path as closely as possible. 3. Fuel savings: After a four-wheel alignment adjustment, the vehicle can travel along the correct path, reducing wind resistance to some extent and consequently lowering fuel consumption. 4. Ensured driving safety: During a four-wheel alignment adjustment, the condition of the vehicle's suspension system and other components is also checked. This inspection can determine whether the tires have any adverse effects on the chassis system.

Can You Still Drive After the Car Overheats?

When the engine temperature is too high, you must stop the car immediately for inspection and must not continue driving. Otherwise, it can easily damage the engine, even requiring major repairs. To determine if the car is overheating, check three things: 1. The temperature gauge. 2. The temperature warning light. 3. Whether there is steam coming out. The temperature warning light should be given special attention because it is more noticeable and easier to see—it will light up first before the car overheats. Common reasons for overheating include: 1. Insufficient coolant. This should be checked first and is basically the only thing you can inspect yourself. If you are on the highway or in a remote area without coolant, you can temporarily use water as a substitute. 2. A dirty radiator. The radiator has many pores formed by cooling fins, which can easily accumulate debris, sludge, and other deposits, reducing airflow and cooling efficiency.

Is Crystal Coating Harmful to Car Paint?

For a new car, crystal coating does not cause damage to the paint surface; however, for a car that has been used for some time, crystal coating can potentially harm the car paint. For a new car, crystal coating only requires deep cleaning of the paint surface, followed by mirror restoration, degreasing treatment, and then applying the crystal coating directly. Since the paint surface of a new car has fewer contaminants and almost no scratches, the process is relatively quick. For a car that has been used for some time, the paint surface must first undergo polishing, followed by mirror restoration, degreasing, and finally, the crystal coating application. Due to various environmental factors causing different degrees of damage to the vehicle, it is essential to remove any contaminants or scratches from the paint surface beforehand to ensure it is smooth, allowing the crystal coating to achieve the best results. Benefits of Crystal Coating: Scratch Resistance: The high hardness of diamond crystals prevents most minor scratches and possesses elastic recovery capabilities. Corrosion Resistance: The ultra-fine nano-crystal layer of diamond crystals isolates the paint surface from the external environment, effectively preventing oxidation and acid rain corrosion. No Cracking: Diamond crystals are resistant to UV rays, extreme temperatures, and strong temperature variations, preventing cracking or peeling. Easy Cleaning: The robust fiber network of diamond crystals fills the tiny pores on the paint surface, achieving a mirror-like effect, making it easier to clean and maintain. Anti-Static: Diamond crystals contain anti-static agents, reducing dust adhesion to the paint surface. Enhanced Shine: The crystal structure of diamond crystals, similar to that of diamonds, increases light refraction, resulting in a brighter and more translucent paint surface.
