"Changing a car's trademark" means modifying the car's registration information.

If the size and weight of the modified vehicle exceed the legal range, the owner usually needs to change the vehicle registration information. In addition, modifications that involve changes in the basic shape of the vehicle body, maximum load capacity, and number of passengers must also be reported. Whether the relevant department accepts the application depends on whether the modified vehicle can meet the security standards. For example, if you replace a non-specified lamp head, you need to check whether its brightness meets the standards. It will not pass if it is too bright or too dark.

The changes to the car may involve "changing the color of the car body, replacing the engine, replacing the body or frame." The car owner should apply for change registration to the vehicle management office within 10 days after the change. The vehicle management office must apply for change registration on the day of acceptance. Handle relevant procedures for vehicle owners, including noting changes on the motor vehicle registration certificate, taking back the driving license, and issuing a new driving license. In other words, car owners who want to modify their cars do not need to apply to the vehicle management office in advance. They can first change the color of the vehicle, replace the engine, etc., and then apply to the vehicle management office for change registration.

Definition of commercial modified vehicles:

The scope of modification of this type of vehicle can involve the following types:

1. Engine - replacing the engine of another model ; Increase the displacement (it can be inferred that replacing an engine with a smaller displacement but the same shape and size does not qualify as [modified vehicle]).

2. Gearbox - replace another form of gearbox (such as stick wave into automatic wave); replace the original mechanical device with an electromagnetic one.

3. Control system - change the position of the steering wheel; change from two-wheel drive to four-wheel drive; change the position of the steering gearbox and rudder scale (left rudder to right rudder falls into this category).

4. Braking system - changed from drum type to disc type braking; use pneumatic operation instead of hydraulic operation.

5. Suspension system - change the type of suspension structure; transform the original leaf spring.

6. Fuel - use another fuel. For example, a gasoline engine is converted to LPG.

7. Transmission device - change the size or material of the transmission shaft. Replace carbon fiber drive shaft, etc.

8. Body - change the front and rear overhang length; change the original form and structure of the single frame.

From October 1, 2008, the revised "Motor Vehicle Registration Regulations" (hereinafter referred to as the "new regulations") will be implemented. Modified vehicles that have always been secretive are expected to obtain official "identity". Under the new regulations, the body color, engine, and body frame can all be registered after modification, and car owners will no longer worry about the annual inspection and registration of modified cars. Article 10 of the new regulations stipulates that if a registered motor vehicle has any of the following circumstances, the owner of the motor vehicle shall apply to the vehicle management office at the place of registration for change registration: changing the color of the body; changing the engine; changing the body or frame . Before this, these modifications were not allowed. Industry insiders said that the new regulations will virtually promote the development of car modification. Although the content is relaxed and the procedures are simplified, there are still strict requirements for modified vehicle specifications. Especially for those who modify the vehicle engine, body or frame, a motor vehicle safety technical inspection certificate must also be submitted.

Supplement: If a professional modification factory purchases a commercial vehicle, after modification, it can sell it with its own car label.

"Some still use Dongfeng's trademarks." Modification factories should have a certain commercial relationship with Dongfeng, rather than a simple sales relationship.

Hope this helps!
