If driving on a four-lane highway, the speed division for vehicles is as follows: when in the leftmost lane, the speed should be between 110 km/h to 120 km/h; when driving in the second or third lane, the speed should be between 90 km/h to 110 km/h; when driving in the rightmost lane, the speed can be below 90 km/h but not lower than 60 km/h. Below is more detailed information: 1. For a three-lane road in the same direction, when a vehicle is in the leftmost lane, the speed should be between 110 km/h to 120 km/h, which is considered the overtaking lane; 2. When driving in the middle lane, the speed should be between 90 km/h to 110 km/h, which is the standard driving lane; 3. When driving in the right lane, the speed should be between 60 km/h to 100 km/h, typically designated for trucks; 4. The rightmost emergency lane should not be entered unless there is an emergency.

I've been driving on highways for decades. The maximum speed limit on four-lane roads is generally set around 120 km/h, but it varies depending on the location - mountainous areas might reduce it to 100 km/h, while urban ring roads could be 110 km/h. The minimum speed on highways is typically 60 km/h, as driving too slowly can easily cause rear-end collisions or traffic jams, so I recommend maintaining a safe speed between 80 to 110 km/h. During rainy or foggy weather, I proactively reduce my speed below 100 km/h to prevent skidding, and always pay attention to roadside speed limit signs which adjust according to road conditions. The key is to develop good habits - don't speed to save time, but don't drive at snail's pace either and make others honk. Safe driving is what really matters.

I usually pay attention to speed when driving. On a four-lane highway, the maximum speed is generally 120 kilometers per hour, and the minimum is around 60 kilometers per hour, but it depends on the signs. I prefer driving between 100 and 110, as it saves fuel without wasting time. Driving too slowly can make others feel blocked, while driving too fast burns fuel quickly and increases the risk of being caught speeding. I recommend using cruise control to maintain a steady speed, especially at night or during long-distance driving. By the way, it's a good idea to regularly check and update the speed limit signs—safety first.

Safe driving is my creed. The maximum speed on a four-lane highway is typically 120 kilometers per hour, while the minimum speed is approximately 60 kilometers per hour on expressways. The minimum speed ensures smooth traffic flow, as driving too slowly can cause trouble; the maximum speed prevents speeding accidents. Always observe road signs and follow the rules to avoid fines or dangers.

Is it safe to use Luqing Petrochemical's gasoline?

Luqing Petrochemical's gasoline meets national quality inspection standards, and generally does not have quality issues. The only drawback is that it may not be as fuel-efficient as gasoline from Sinopec and PetroChina. Therefore, car owners can use it with confidence. If you are still concerned, it is recommended to use gasoline from Sinopec or PetroChina. The following are some details about Luqing Petrochemical's gasoline: 1. Detail one: To survive in the market, Luqing Petrochemical can only adopt a "price war" strategy to secure a customer base. Additionally, as a large private enterprise, Luqing Petrochemical strictly controls costs, which naturally leads to lower gasoline prices. 2. Detail two: Luqing Petrochemical is located in Shandong, a region in East China along the coast and the lower reaches of the Yellow River, where petroleum resources are abundant. There are many private refineries and oil enterprises in Shandong, resulting in a severe oversupply. This is the direct reason why Luqing Petrochemical's gasoline is cheaper. 3. Detail three: Long-term use of Luqing Petrochemical's gasoline has no significant impact on vehicles. As a large enterprise, its gasoline quality, while not as good as that of the "two barrels" (Sinopec and PetroChina), is still decent.

Can I drive if my license plate is washed away by water?

If your license plate is washed away by water, you cannot drive on the road and need to immediately apply for a temporary license plate. You should go to the relevant vehicle management department to reapply for a license plate as soon as possible. Since the replacement cycle for a new license plate takes 8 working days, you must obtain a temporary license plate to drive legally. Below is relevant information about license plates: 1. License plate material: Vehicle license plates are plates hung on the front and rear of the car, usually made of aluminum, plastic, or stickers, displaying the vehicle's registration number, registration area, or other basic information. 2. Function: The license plate is a numbering system for vehicles. Its main purpose is to identify the province, city, or county the vehicle belongs to, and the vehicle management office can use the license plate to find the owner of the vehicle.

Can You Make a U-Turn When Turning Left at an Intersection?

Left turns do not allow for U-turns. More details about vehicle U-turns are as follows: 1. Detail one: Vehicles are not permitted to make U-turns at locations with signs or markings prohibiting U-turns or left turns, including railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or any other hazardous sections. Vehicles can make U-turns at locations without signs or markings prohibiting U-turns or left turns, but they must not obstruct the normal passage of other vehicles and pedestrians. U-turns at intersections are not restricted by traffic lights. 2. Detail two: At intersections without signs or markings prohibiting U-turns (or left turns), U-turns are legally allowed regardless of whether the traffic light is red or green. However, if there is a clear sign at the intersection indicating "when the left turn light is green" or "when the red light is on," then U-turns must be made according to the signal timing specified on the sign.

What is the speed of an electric vehicle?

Currently, the fastest electric vehicle in the world has a top speed of up to 323 km/h. Below is a relevant introduction to electric vehicles: 1. Power Source: The power source provides electrical energy to the driving motor of the electric vehicle, which converts the electrical energy into mechanical energy. The most widely used power source currently is lead-acid batteries. However, with the advancement of electric vehicle technology, lead-acid batteries are gradually being replaced by other types of batteries due to their low energy density, slow charging speed, and short lifespan. 2. Composition: Includes the electric drive and control system, mechanical systems such as the driving force transmission, and working devices to accomplish set tasks. 3. Core: The electric drive and control system is the core of an electric vehicle and also the biggest difference that sets it apart from internal combustion engine vehicles.

What Causes the Hissing Friction Sound from the Front Wheels When Turning at Low Speed?

Low-speed turning with a hissing friction sound from the front wheels is caused by excessive wear of the brake pads, leading to abnormal noise. It is necessary to promptly inspect the brake pads and replace them if needed. Below is relevant information about brake pads: 1. Brake Pad Maintenance: The effectiveness of a car's braking system is largely determined by the brake pads, which are crucial for the vehicle. Regular inspection and protection are essential. Under normal driving conditions, the brake pads should be inspected every 5,000 kilometers. Not only should the remaining thickness be checked, but also the wear condition of the pads, whether the wear on both sides is even, and whether they retract smoothly. Any abnormalities must be addressed immediately. Brake pads should be replaced when their thickness is reduced to approximately 0.5 cm. 2. Brake Pad Replacement: When replacing brake pads, it is best to use original equipment manufacturer (OEM) parts. This ensures the best braking performance and minimizes wear between the brake pads and discs. After replacement, it is important to pump the brakes several times to eliminate any gap between the pads and the brake discs.

Why does an electric vehicle lack power at startup but runs fine afterwards?

Electric vehicles lacking power at startup but running fine afterwards may be caused by voltage issues or battery problems, and specific troubleshooting should be conducted by a 4S shop. Below is relevant information about electric vehicle batteries: 1. Optimal battery temperature: Since the optimal temperature range for battery cells is 0-40°C, temperatures that are too high or too low can affect the activity of the cells, cause irreversible damage, and even impact battery lifespan. When charging an electric vehicle, if the battery temperature is below 0°C, the battery needs to be preheated before charging, which also prolongs the charging process and is detrimental to battery maintenance. 2. Battery usage precautions: During vehicle charging, the battery pack temperature rises. If the temperature difference is too large, it can trigger chemical reactions in the active materials on the positive and negative plates, thereby shortening battery life. Conversely, when the battery temperature is too low, it reduces the battery's storage capacity, making it prone to over-discharge, which further shortens battery lifespan.
