Vehicle Identification Number is the chassis number, referred to as VIN. It is a unique set of seventeen letters or numbers used on automobiles to identify the manufacturer, engine, chassis serial number, and other performance data of the vehicle. There are mainly two formats of vehicle identification numbers. The first is the ISO3779 standard adopted by the European Union, and the second standard is mainly used in North America, which is more stringent than the first but still compatible with it. Every car, truck, or trailer manufactured in the United States after 1981 has a VIN, and this number is fixed. No two vehicles manufactured within 30 years can have the same VIN. The motor vehicle driving record database contains information related to the VIN, such as the vehicle's inspection time, ownership change time, and whether it has been involved in serious accidents such as crashes, rollovers, or floods.

To be honest, the Vehicle Identification Number (VIN) is like a unique ID card for each car, consisting of 17 characters. It's usually engraved under the windshield or on the door pillar. As someone who frequently deals with cars, I always check the VIN carefully when buying a vehicle because it can reveal a lot of secrets: the first three alphanumeric characters represent the manufacturer (e.g., 'F' stands for Ford); the middle section describes the model and year; and the last few digits are the serial number, used for anti-counterfeiting. Its most practical benefit is checking accident history or recall information—I can enter the VIN online to get a full report, avoiding problem cars. It’s also essential for registration, insurance, and even selling used cars, as it verifies identity quickly and efficiently while helping prevent theft (police use it to recover stolen vehicles). Remember, always verify the VIN when buying a used car—don’t just judge by its shiny exterior. This can save you from many pitfalls.

What does it mean to drive a non-commercial motor vehicle?

Non-commercial motor vehicles are those not used for profit-making purposes. Here are the detailed explanations: 1. Types: Generally, private cars and company-owned vehicles for self-use are non-commercial vehicles. Non-commercial motor vehicles are not allowed to engage in commercial activities; otherwise, they will be penalized. If they need to participate in commercial activities, the owner must apply to change the vehicle's nature at the vehicle management office of the traffic management department under the public security organ where the vehicle is registered. 2. Regulations: Non-commercial private cars are no longer subject to the 15-year mandatory scrapping limit. As long as the vehicle is in good condition and passes the annual inspection, it can be used continuously until the mileage reaches 600,000 kilometers, after which it may be guided to be scrapped by the traffic police department. However, commercial vehicles will be guided to be scrapped by the traffic police department after 8 years of use.

What Causes the Noise from Suspension Springs When Turning?

The noise from suspension springs when turning can be caused by various reasons. Here is a detailed explanation: 1. Friction between plastic components: Since the steering wheel is usually made of plastic parts, if the temperature drops, the plastic becomes harder, which can naturally lead to friction noise. 2. Noise coming from the steering wheel: If the noise originates from the steering wheel, the issue is most likely due to the clock spring (spiral cable) inside the steering wheel. Remove the steering wheel and apply some grease to the clock spring to see if the noise persists. If it does, replace the clock spring as it may be damaged. Be gentle when removing the steering wheel, or disconnect the airbag fuse to prevent the airbag from deploying. 3. Aging of the tie rod end ball joint: If the tie rod end ball joint is aged, it can cause the car's steering wheel to shake and produce noise. In such cases, the tie rod end ball joint should typically be replaced, followed by a four-wheel alignment.
