Highway four-lane speed limits are as follows: 1. The first lane from left to right: 100-120 km/h. Generally reserved for passenger cars. 2. The second lane: 80-100 km/h. 3. The third lane: 60-100 km/h. 4. The fourth lane: Emergency lane. Some highways may have different regulations, so always follow the marked speed limits on the road. When driving on a highway, pay attention to the following: 1. Always adhere to the speed limit. The maximum speed limit on Chinese highways is 120 km/h, and different lanes may have varying speed limits, which are indicated by roadside signs. Speeding is a major cause of accidents, so avoid it at all costs. At the same time, avoid driving too slowly, as this can disrupt normal traffic flow. 2. When entering the main lane from an on-ramp, use the acceleration lane to reach an appropriate speed before merging. Do not obstruct vehicles already in the main lane. 3. Clearly distinguish the purpose of each lane and drive accordingly. Generally, stay in the main lane and only use the overtaking lane when necessary to ensure smooth traffic flow. 4. Follow speed limit regulations. Speeding can lead to accidents, while driving too slowly can hinder other vehicles. Reduce speed during rainy conditions. 5. Always watch for roadside and overhead signs and markings. Stay slightly to the right to avoid crossing the right lane divider, giving overtaking vehicles sufficient side clearance.

I've been driving on the highway for over a decade, so I'm quite familiar with lane speeds. The leftmost lane (first lane) is the fastest, with a minimum speed of 110 km/h and a maximum of 120 km/h – it's the overtaking lane. The second lane has a minimum of 90 and maximum of 120 km/h, where most passenger cars usually drive. The third lane has a minimum of 80 and maximum of 100 km/h, mainly used by trucks. The far-right fourth lane has a minimum of 60 and maximum of 100 km/h, often used by buses and trucks. But remember, the emergency lane on the far right is absolutely off-limits! I once saw someone get heavily fined for stopping there to repair their car. Don't just rely on your speedometer – always pay attention to road signs, as speed limits can suddenly drop to 80 km/h in tunnel areas.

Every time I drive on the highway, I enjoy observing the lane conditions and notice many drivers are confused about speed limits. The leftmost overtaking lane must maintain 110-120 km/h – driving too slow there risks rear-end collisions. The second lane from the left allows 90-120 km/h, which is my usual cruising choice. The third lane permits 80-100 km/h and is often occupied by trucks. The rightmost lane has the broadest range at 60-100 km/h but frequently has slow-moving vehicles. Last month, I encountered someone doing 80 km/h in the overtaking lane, causing a long queue behind. It's crucial to read lane markings correctly, especially during rainy or foggy conditions when you should reduce speed.

How many days does it take to receive the 2021 Sagitar after ordering?

The 2021 Sagitar usually arrives at the 4S store within 7 to 15 days after ordering, but there may be exceptions. This is because the vehicle needs to undergo factory inspections, and road transportation takes time. Here are some tips for car owners when picking up their vehicle: 1. Inspect the body: Check for scratches or wear on the paint. It's best to examine the paint under bright sunlight to spot any color differences. You can also open the doors and view the body from different angles to check if the sheet metal is even. 2. Check the vehicle's identification plate: The plate is located on the driver's side door or in the engine compartment, and you should note the manufacturing date. 3. Inspect the windshield: If the glass is a year or more older than the vehicle's production date, it may have been replaced. 4. Check the engine compartment for cleanliness: If the vehicle has been stored for a long time or used, there may be noticeable dust or stains in certain areas. 5. Check the doors: Ensure they open and close smoothly, and that the gaps between doors and bumpers are consistent. 6. Check the tire production date: This is another way to determine if the car has been in stock for a long time.

What is the normal SOC for a car battery?

Under normal circumstances, the battery voltage before starting the car should be between 11.8V and 12.8V, and after starting, it should be between 13.2V and 14.8V. As long as the voltage during startup is not lower than 11V, it is considered normal. Signs of a failing car battery are as follows: 1. Difficulty starting the car: If the car suddenly has difficulty starting without any other factors, it may be a sign that the battery is about to fail. 2. Dimming lights when the car is idling: For example, when stopping at a red light or temporarily parking, the headlights suddenly become dim. This is because the charging power of the engine decreases when idling. 3. Battery warning light comes on: When the battery warning light comes on, it is a reminder for the owner to go to a repair shop for battery maintenance and testing. 4. Normal driving most of the time, but occasionally the car has no power after parking and restarting: This is because when the battery is nearing the end of its life, the starting current is insufficient, causing an increase in oxide on the battery terminals, resulting in a complete loss of power.

What is the function of an automotive fuel pump?

Automotive oil pumps are divided into two parts: the engine oil pump and the gasoline pump. The engine oil pump is installed inside the engine. It transports engine oil to various parts of the engine, particularly between components that rub against each other, ensuring lubrication between these parts. This practice guarantees that the engine receives proper lubrication. Below is an introduction to automotive fuel pumps: 1. Fuel Pump: The fuel pump is a professional term in the automotive parts industry. It is one of the fundamental components of the fuel injection system in electronically fuel-injected vehicles, located inside the fuel tank. The fuel pump operates during startup and while the engine is running. If the engine stops but the ignition switch remains in the ON position, the HFM-SFI control module shuts off the power to the fuel pump to prevent accidental ignition. 2. Electric Centrifugal Booster Pump: The electric centrifugal booster pump serves as an auxiliary fuel pump in the fuel system. The motor is typically mounted on a wing beam corresponding to the lower position of the fuel tank, while the pump body is submerged in the fuel at the bottom of the tank. Sealing measures are implemented between the pump impeller and the motor to prevent fuel or fuel vapor from leaking into the motor. When fuel enters the pump body, the high-speed rotating impeller radially propels the fuel outward, generating centrifugal force, increasing fuel pressure, and delivering the fuel to the system.

Do Cars Have a Warranty Period?

Do Cars Have a Warranty Period? Cars do have a warranty period. The car warranty period refers to the timeframe during which the car manufacturer promises to provide free repairs and maintenance for any faults arising from quality issues when selling the product to consumers. Most car manufacturers now implement a new vehicle warranty period of "two years or 60,000 kilometers, whichever comes first." This means there are two conditions for the warranty period: one is a time limit of two years, and the other is a mileage limit of 60,000 kilometers. If either of these conditions is met, it indicates that the vehicle's warranty period has expired, and any subsequent normal maintenance or repairs will no longer be free. Additionally, during the warranty period, not all repair costs will be covered. It depends on the free items specified by the manufacturer within the warranty period. Usually, relevant descriptions can be found in the owner's manual and the after-sales departments of car 4S stores. Therefore, car owners are advised to carefully read the manual to avoid unnecessary expenses during the warranty period. Generally, the 60,000-kilometer warranty mainly covers the core components of the car, such as the engine, transmission, drivetrain, and chassis. The probability of failure for these components is relatively low, and the repair costs are high. Moreover, within this mileage range, such faults are less likely to occur. For wear-and-tear parts like tires, rims, headlights, and brakes, car dealers usually only provide a warranty of 3-6 months or 5,000 kilometers.

What is the impact of a driver's safe driving record?

Querying a driver's safe driving record is aimed at encouraging safe driving practices among drivers. Here is some extended information regarding traffic violation handling: 1. Time frame: Vehicle owners must report to the local traffic police station within 15 days of receiving the penalty notification after a violation. Failure to do so within this period will result in a daily late fee of 3% of the original fine, though the total late fee will not exceed double the original fine amount. Early handling helps avoid unnecessary penalties. 2. Confirmation method: The quickest and most effective way to check for violations is to visit the vehicle management office or traffic police station. Essential documents to bring include your driver's license, vehicle registration, and ID card—all three are mandatory. It's also advisable to carry some cash, so you can immediately process any violation records found.

Does wheel hub painting require registration?

Changing the color of wheel hubs does not require registration with the vehicle management office. The wheel hub is an important component of a car, shaped like a cylindrical barrel, also known as a steel ring, tire bell, wheel, or rim. It is the rotating part of the wheel steel inside the tire connected by pillars to the wheel core, essentially a metal component mounted on the axle to support the center of the tire. Below is extended information about wheel hubs: 1. Upgrading the size of wheel hubs, the overall size modification of imported wheel hubs includes increasing by 2 inches and 1 inch. That is, based on the original wheel hub, the width and diameter of the hub are increased by 2 inches or 1 inch simultaneously. 2. Upgrading the width and quality of wheel hubs. Tire upgrades are not just about upgrading the tires; the wheel hubs must also be upgraded. Only after determining the tires to be replaced can the wheel hubs be selected. After determining the diameter, the width of the wheel hub is decided. 3. The design of the wheel hub is determined by its material. Aluminum-magnesium alloy wheel hubs perform better in all aspects compared to steel wheel hubs.
