White semicircular markings refer to distance confirmation lines, which typically appear on highways; the hemispherical radius of white semicircular distance confirmation lines is 30cm, spaced at 50m intervals, and are usually set consecutively over certain road sections. Additional information: Purpose of white semicircular markings: Distance confirmation lines primarily serve to remind drivers to maintain a safe following distance from the vehicle ahead to prevent traffic accidents. Distance confirmation lines generally come in three forms: white zigzag distance confirmation lines, white semicircular distance confirmation lines, and white rectangular distance confirmation lines.

To be honest, I often notice those white semicircular markings on the road, mainly appearing in front of sidewalks or near intersections. These markings are actually warning signals designed by traffic authorities to remind us drivers to slow down, stop, and give priority to pedestrians. If accidentally ignored, you might be caught on camera for a violation fine or cause congestion accidents during peak hours. Last time I saw them near a school, I immediately slowed down, avoiding a potential collision with students crossing the road. Remember, parking is absolutely prohibited in these areas, as it could endanger pedestrian safety. Developing the habit of observing road signs not only ensures safety but also saves trouble. Always slow down in advance when encountering them, especially at night or during rainy weather, to maintain clear visibility.

As a seasoned driver with decades of experience, let me tell you that those white semicircular markings are extremely common on streets, especially at intersections or in residential areas. They primarily serve as no-parking zone warnings, indicating that parking within this area would obstruct pedestrian and vehicle passage. I've seen many people ignore these markings, leading to minor collisions or traffic tickets. In actual driving, spotting these markings means you should prepare to brake, as they hint at potential hazards ahead, like pedestrian crossings. Experience has taught me that extra vigilance prevents accidents, and regularly checking road signs enhances overall driving comfort. Remember, safety first—these markings are silent reminders.

What is the function of car paint?

Car paint serves to protect the vehicle from various corrosive elements in the atmosphere, decorate the car, indicate the type of vehicle, improve comfort and sealing, and prevent noise caused by vibration. Below are the principles and composition of car paint: Principles of car paint: The main component of car paint is resin, which has relatively large molecular gaps. After coating, small molecular elements such as silicon, silicon dioxide, and nano-inorganic silicon in the coating solution can fully penetrate into the molecular gaps and micropores of the car paint, forming a transparent crystalline layer on its surface similar to a smartphone screen protector. This significantly enhances the hardness and scratch resistance of the car paint surface, providing long-term sealing protection and keeping the car paint bright and new for a long time. Composition of car paint: The car paint surface consists of four layers, from the inside out: the electrophoretic layer, the middle coat layer, the color paint layer, and the clear coat layer. After the entire body is assembled, it is immersed in an electrophoretic tank, forming an electrophoretic layer on the surface of the body.

What is the normal voltage range for a 12V car battery?

Car 12V battery normal voltage range: No-load voltage is around 13V, load voltage should not be lower than 11V. Effects of abnormal battery voltage: Both excessively high or low battery voltage will cause certain impacts. Regular inspection of battery condition is recommended. When battery voltage drops below 10.8V, immediate charging is required. If battery voltage is too low, the vehicle may experience difficulty starting or complete failure to start. If battery voltage is too high, it may damage the battery. Voltage measurement methods: Use a multimeter to check the battery voltage during engine cranking. First measure with a high-frequency discharge meter or battery tester - under load current not less than 110A, the minimum voltage should not be lower than 9.6V and remain stable for 5 seconds. If voltage is below 9.6V but remains stable for 5 seconds, it indicates over-discharge and requires immediate charging. If voltage drops below 9.6V and cannot remain stable within 5 seconds, rapidly decreasing to 0V or near 0V, this indicates battery failure requiring replacement.

Can a Car with Tuned ECU Pass the Annual Inspection?

If the car is only tuned to stage 1 or 2, it will not affect the annual inspection. However, if it is tuned to stage 3, it will fail the annual inspection because too many modifications are required. The so-called stage 1, stage 2, and stage 3 refer to the tuning of the ECU program. Below are the impacts of ECU tuning and the items checked during the annual inspection: ECU tuning has the following effects on the car: After ECU tuning, the car will require higher-quality gasoline. Using low-quality gasoline may damage the vehicle. The temperature requirements also increase. After ECU tuning, the engine operates at higher frequencies, and without a proper cooling system, it may affect the engine's lifespan. The 4S store may refuse warranty services for vehicles with tuned ECUs. Items checked during the annual car inspection: Exterior inspection, exhaust emission test, window film transparency check, traffic violation check, and safety inspection, which includes a comprehensive check of the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, license plate installation, etc.

What is the fuel consumption of the CFMOTO 150nk?

CFMOTO 150nk has one model currently on sale, which is the CFMOTO 150nk (2021 model) motorcycle, equipped with a 150ml engine. The NEDC fuel consumption is 2.5L per 100 kilometers. The fuel tank capacity of different CFMOTO 150nk models varies. The distance that can be covered with a full tank of fuel is as follows: For the model equipped with a 150ml engine, the fuel tank capacity is 10L, and the distance that can be covered with a full tank is 10/2.5*100=400km. The fuel consumption of a motorcycle is directly related to five major factors: driving habits, the vehicle itself, road conditions, natural wind, and environmental temperature. Driving at an economical speed of 50 to 60 kilometers per hour is more fuel-efficient. Avoid sudden acceleration and braking, try to maintain a steady and smooth speed, and properly match the vehicle speed with the engine RPM for better fuel efficiency. The specific factors that can increase motorcycle fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not releasing the throttle in advance when approaching a red light, can increase fuel consumption. The vehicle itself: Vehicles with larger displacement engines generally consume more fuel than those with smaller displacement engines because larger displacement engines usually have higher power output and require more fuel to burn for work. Heavier motorcycles also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases vehicle resistance and fuel consumption. Low environmental temperatures: When the engine block temperature is low during cold starts, the injected fuel does not atomize easily, requiring more fuel to burn, which increases fuel consumption. Additionally, in low temperatures, the engine's computer will control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

Is Commercial Insurance Still Valid After Vehicle Transfer?

After the vehicle is transferred, the insurance can still be used. Vehicle insurance includes compulsory insurance and commercial insurance. The transfer of used car insurance needs to be done after the used car transaction is completed, and after the registration certificate owner information is changed, and the new vehicle license plate and driving license are obtained. Used car insurance does not necessarily have to be transferred; you can choose to cancel the insurance directly, but the compulsory insurance must be retained. Transfer documents: Seller: Owner's ID card, vehicle registration certificate, vehicle driving license, original purchase invoice (or transfer ticket if previously transferred). If the seller is a company, the original business license and official seal are required. Buyer: ID card. If the buyer is from another city and needs a local license, a valid temporary residence permit is also required. If the buyer is a company, the original business license and official seal are required. Original vehicle purchase invoice or the last transfer invoice. Original vehicle driving license. Vehicle registration certificate (green book). For outbound transfer, the small book of vehicle purchase tax is required. Relevant content about used car insurance transfer: Compulsory insurance change. According to the "Compulsory Insurance Regulations," in used car transactions, compulsory insurance cannot be canceled in principle. The only situation where cancellation is allowed is when the vehicle is sold to another region, in which case the new owner can purchase compulsory insurance in the new location. The new owner needs to bring their ID card, new driving license, used car transfer documents, and the newly issued compulsory insurance policy to the original owner's insurance company for cancellation. Timely change of commercial insurance. After the transfer of a used car, attention should not only be paid to the transfer of compulsory insurance but also to commercial insurance matters. For locally purchased used cars, the change requires the new owner and the original owner to bring the original policy, ID cards, new driving license, and transfer certificate to the original insurance company for processing. For used cars purchased from another region, as some insurance companies cannot underwrite policies across regions, the original owner can cancel the commercial insurance with the insurance company, and then the new owner can purchase new commercial insurance in the new location. If the insurance company offers nationwide coverage, the branch in the new location can contact the original underwriting branch to inquire about the transfer procedures. If cancellation is desired, the original owner's policy and ID card must be provided. After cancellation, the new owner can purchase new car insurance from any insurance company by providing the new driving license or vehicle transfer certificate. The documents required from the original owner for used car transfer include: registration certificate, driving license, and ID card. The buyer needs to provide an ID card, and if they are from another city, a residence permit or temporary residence permit is required. Vehicle transfer first requires a vehicle evaluation. The evaluation fee is generally 1%-2% of the evaluated vehicle price, and other fees include license plate and driving license costs. The original commercial insurance can be canceled (compulsory insurance cannot be canceled), or it can be transferred to the buyer at the insurance company. Precautions for purchasing used cars: Incomplete documents. Complete documents for a used car include: vehicle registration certificate (or original purchase invoice), driving license, vehicle purchase tax payment certificate, road maintenance fee documents, and compulsory insurance. If the vehicle registration certificate or driving license is missing, or if there are unpaid compulsory insurance or road maintenance fees, it will cause endless trouble for the buyer. Therefore, when purchasing a car, if the seller cannot provide complete documents, the buyer should be particularly cautious. Tampering with the odometer. Most consumers like to judge the condition of a car by the odometer, and sellers often take advantage of this psychology to tamper with the odometer. In fact, the odometer is not only a record of usage intensity but also an indicator of the maintenance and replacement of other vehicle components. If the buyer follows the maintenance schedule based on a tampered odometer, it will bring a series of potential safety hazards. New paint covering external damage. When purchasing a used car, if the car has been repainted and there are signs of repair around the front, rear, and A, B, C pillars, the car may have been involved in a major accident.
