Here are the methods to check the emission standard on the vehicle license: 1. Check the vehicle's environmental protection label, which has a clear mark on the back; 2. For new vehicles, you can check the vehicle's factory certificate or vehicle conformity certificate; 3. You can log in to the public inquiry platform of the Motor Vehicle Environmental Protection Network, enter the vehicle's VIN number and the last 6 digits of the engine number to query the vehicle information. Additional information: If the vehicle meets the National 5 emission standard, the implementation of the National 6 standard will not affect normal road use, as vehicles already sold are subject to the emission standards at the time of sale. Therefore, as long as the National 5 vehicle is in good condition, it can continue to be driven.

The vehicle license does not directly indicate the national emission standard, but it can be roughly inferred from the registration date. For example, my car was registered in 2010, and according to the timeline, vehicles from that year are usually compliant with the China IV emission standard, as emission standards are upgraded every few years. Most vehicles registered between 2005 and 2008 are China III, while those registered between 2011 and 2016 are mostly China IV or China V. The back of the vehicle license shows the registration date and vehicle model, so checking the year carefully can give you a clue. Emission standards are related to annual inspections and environmental traffic restrictions. Last time I entered the city, I was checked because my old car had low emissions. To confirm, you can download the 'Auto Environmental Protection' app and enter the VIN to check detailed data, which is both simple and reliable. Remember, the date is your main clue—don't overlook this small detail.

To check the emission standard, the vehicle license itself doesn't indicate the specific national emission level (e.g., China III, IV), but it contains crucial clues. Flip through the license to find the registration date - a car registered in 2009 might be China III, while 2014 models are often China IV or V. Emission standards have become stricter over time, with earlier standards being more lenient. On car enthusiast forums, I learned that the vehicle model number sometimes hints at the emission level - for instance, certain codes containing '03' may represent China III. Emission standards significantly impact vehicle value and policies. I recommend entering the license details into the 'National Vehicle Emission Inquiry Platform' for a quick one-minute verification. In short, don't guess blindly - use the registration date as your key.

Bring your ID card and vehicle license to the vehicle management office at the vehicle's registration location and fill out the application form for reissuing the annual inspection sticker. 2. Submit the documents and application form to the staff. 3. The vehicle management office will review the materials. If they meet the requirements, the relevant materials will be stored, information will be recorded, and the vehicle inspection compliance sticker will be issued. Annual inspection refers to a mandatory test for every vehicle that has obtained an official license plate and vehicle license, equivalent to an annual physical examination for the vehicle according to the safety technical conditions for motor vehicle operation. Annual inspections can promptly eliminate potential vehicle safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents.

Under What Circumstances Should High Beams Be Used?

Generally, high beams should be used when driving on roads with poor lighting conditions, such as highways. However, when encountering other vehicles, drivers should switch to low beams and then revert to high beams afterward. Additional information on the use of high beams is as follows: 1. If high beams are used improperly at night, they can interfere with the visibility of surrounding vehicles and create safety hazards. According to national laws, low beams should be used when driving on roads without central barriers or when meeting non-motorized vehicles on narrow roads. 2. High beams should not be used at intersections controlled by traffic signals. Due to their intense light, high beams can cause temporary glare, making them generally prohibited in urban areas. When overtaking at night, drivers should alternate between high and low beams to alert the vehicle ahead.

Why Does the Car Body Shake on the Highway?

Here are the reasons why the car body shakes on the highway: 1. Excessive carbon deposits. If there is severe carbon buildup inside the engine cylinders, it can lead to clogged spark plugs and valves, directly causing the car to shake at idle. If the car's acceleration performance has significantly declined and the shaking persists, consider cleaning the engine cylinders. 2. Fuel system failure. Unstable fuel pressure can cause fluctuations in the air-fuel mixture concentration, not only resulting in shaking but also unstable idling. First, consider replacing the fuel filter and then check the fuel pressure. If abnormal, the issue might be with the fuel pump. 3. Worn engine mounts. If the engine shaking becomes increasingly severe but the power output remains unaffected, the problem could lie with the engine mounts. 4. Misfiring is the most common cause of engine shaking. The issue may stem from faulty ignition coils or spark plugs. If the ignition coil malfunctions or the spark plug fails to fire for any reason, the car will experience shaking.
