It is necessary to wash your car before applying window film. If the car body is not clean, bumps may appear after the film is applied, which not only affects the appearance of the car but also makes the raised areas more prone to damage. Car window film involves applying a thin layer of material to the front and rear windshields, side windows, and sunroof of the vehicle. This thin material is also known as solar film or heat-insulating film. The primary functions of solar film include blocking ultraviolet rays, reducing heat transmission, preventing injuries from shattered glass, minimizing glare, and, due to its one-way transparency, protecting personal privacy. Solar film can also reduce damage to interior items and passengers caused by UV exposure. By reflecting sunlight, it helps lower the interior temperature, reducing the need for air conditioning and thereby improving fuel efficiency.

What is the purpose of automotive urea?

Automotive urea is a liquid used in SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxide (NOx) pollution in diesel vehicle exhaust. It is composed of 32.5% high-purity urea and 67.5% deionized water. Automotive urea is synthesized by blending high-quality agricultural urea with ultrapure water in specific proportions. According to national standards, there are strict requirements for the density, refractive index, alkalinity, metal ion content, and impurities in automotive urea. The primary harmful substances in diesel vehicle exhaust are nitrogen oxides and particulate matter. While particulate emissions can be reduced through technical means within the engine, the remaining exhaust mainly consists of nitrogen oxides. By injecting automotive urea into the exhaust after-treatment device, the urea decomposes into ammonia at high temperatures, which then reacts with nitrogen oxides in the presence of a catalyst to form harmless nitrogen and water. This process is known as the SCR after-treatment system.

How often is the annual vehicle inspection required?

Annual vehicle inspections are required once every year. For vehicles over 10 years old, inspections are required every 6 months. Small and micro non-operational passenger vehicles within 6 years require inspection once every 2 years; after exceeding 6 years, inspection is required once every year; after exceeding 15 years, inspection is required every 6 months. If a motor vehicle fails to obtain the inspection compliance mark for 3 consecutive inspection cycles after the expiration of the valid inspection period, it will be mandatorily scrapped. Vehicles that do not undergo inspections on time not only lack driving safety guarantees but will also result in a 3-point penalty for the driver according to the Road Traffic Safety Law. For any traffic accidents caused by vehicles that have not undergone timely annual inspections, the involved party will bear full or primary responsibility, and the insurance company will not assume any liability.

How Early Can You Obtain the Annual Inspection Sticker?

You can obtain the annual inspection sticker up to three months in advance. According to the regulations on motor vehicle registration, the owner of a motor vehicle may apply for the inspection compliance sticker at the local vehicle management office up to three months before the expiration of the current inspection validity period. Before applying, the vehicle owner must resolve all traffic violations and accidents related to the vehicle. Vehicle annual inspection refers to a mandatory test for all vehicles that have obtained formal license plates and registration certificates. It is equivalent to an annual 'health check' for the vehicle based on the technical safety requirements for motor vehicle operation, aiming to promptly eliminate potential safety hazards, encourage better vehicle maintenance, and reduce the occurrence of traffic accidents.

Can vehicle annual inspection be conducted in another location?

Vehicles can undergo annual inspection in another location. Since September 1, 2018, cross-province off-site inspections have been fully implemented for small cars, trucks, and medium-sized buses. Applicants can directly conduct inspections and obtain inspection qualification marks in provinces other than the motor vehicle registration location without the need to go through entrusted inspection procedures. Issues to note for off-site annual inspections include: 1. The procedural requirements for off-site entrusted annual inspections mandate that the vehicle owner must first apply to the original registration location before proceeding with the annual review, and an application must be submitted to the vehicle management office of the original vehicle registration location every year; 2. The motor vehicle involves unprocessed road traffic safety violations and accidents.

Can vehicle annual inspection be conducted across provinces?

Vehicle annual inspection can indeed be conducted across provinces. After the implementation of the new regulations, cross-regional vehicle inspections are divided into intra-provincial and inter-provincial inspections. The procedures for intra-provincial inspections are the same as those for local inspections. For inter-provincial inspections, the vehicle owner needs to return to the registration location of the vehicle to obtain a cross-regional inspection authorization letter before returning to the location where the vehicle is used to undergo the annual inspection. The required materials for cross-regional inspections are as follows: 1. Original ID card or the original ID card of the agent; 2. Original vehicle registration certificate; 3. Copy of compulsory traffic insurance; 4. Proof of vehicle and vessel tax. In September 2018, the requirement for a cross-regional inspection authorization letter was abolished for inter-provincial vehicle inspections. Starting from September 2018, vehicles can undergo annual inspections in any city nationwide following the standard procedures.
