Why is traffic violation code 10871 not handled on the spot?

[LawsonFitz]

Violation code 10871 refers to unauthorized modification of a motor vehicle's appearance, with a penalty of 0 demerit points and a fine of 500 yuan. According to regulations, the fine should be issued with a unified receipt from the provincial, autonomous region, or municipal finance department; if such a receipt is not provided, the party involved has the right to refuse payment. Generally, traffic police do not carry receipts with them, so this violation is not handled on the spot. Relevant regulations on vehicle modifications are as follows: The style of the wheel rims can be changed, but the specifications must match those on the motor vehicle registration certificate. The height-to-width ratio of a modified roof rack must be controlled within 300mm, and the width of side steps cannot exceed 5cm beyond the vehicle body's side profile. The vehicle's color can be changed through painting or wrapping, but within ten days of the change, the vehicle must be taken to the vehicle management office to update the vehicle information. It is important to note that colors similar to those used on emergency vehicles such as police cars or fire trucks are prohibited. Illegal vehicle modifications can pose safety hazards and increase the risk of accidents. Therefore, modifications must be legal and promptly registered. There are four common ways to check for motor vehicle violations: Visit the office halls of traffic departments in various districts and counties to use touch-screen terminals for inquiries. Log in to the public service websites of local public security traffic management bureaus, locate the vehicle violation query section, enter the license plate number and engine number, and click to query. Call the inquiry hotline (area code + 114). Use the "Traffic Management 12123" app to check.
