How is the installation of a rear wing penalized?
4 Answers
If the installed rear wing is a small decorative one, it is not considered illegal and will not be penalized. However, if an excessively large rear wing is installed without filing with the vehicle management office, being caught by traffic police may result in a penalty of 2 demerit points and a fine of 200 yuan. The penalty standards may vary depending on local regulations. Additional information is as follows: 1. The essence of vehicle modification: Vehicle modifications generally include modifications to the vehicle's power and its appearance. Modifying the vehicle's power involves reprogramming the engine. 2. Notes on vehicle modification: Generally, installing relatively small front splitters, rear lips, and rear wings is not illegal, whereas modifying wide body kits is illegal and must be approved by the local vehicle management office. After obtaining approval from the local vehicle management office, it is necessary to immediately file for registration; otherwise, it may affect the vehicle's annual inspection. When taking a modified vehicle for an annual inspection, it is best to restore the car to its factory state to avoid unnecessary troubles during the inspection, which can waste both time and money.
Last time we talked about this in the car enthusiasts group, my neighbor learned it the hard way last year. He spent thousands installing a carbon fiber spoiler, only to be pulled over by traffic police at the highway exit, fined 500 yuan on the spot and deducted 3 points. The key issue was that the vehicle registration certificate photo didn't match the actual car. In the end, he had to remove the spoiler and go through vehicle reinspection at the DMV. Now with stricter new regulations, privately installed spoilers exceeding 30cm are directly considered illegal modifications and will definitely fail annual inspections. If you really want to modify, I suggest applying for modification registration at the DMV in advance to legally adjust the vehicle parameters. Some cities now offer online processing channels for this.
From a regulatory perspective, installing an unregistered rear spoiler violates Article 16 of the Motor Vehicle Registration Regulations. I've seen many cases: in Shanghai, fines range from 200-500 RMB with orders to restore the original condition; Shenzhen directly impounds the vehicle until restoration; Beijing even records it in the credit system. The worst part is the insurance risk - my auto repair shop friend says insurers will deny claims if they discover spoiler modifications on accident vehicles. And don't believe online claims that small spoilers don't matter - tests show spoilers over 20mm affect airflow at high speeds, causing misjudgment by rear vehicle radars. If a rear-end collision occurs, you'll bear full responsibility.
Actual penalties depend on three factors: First, check if the vehicle is registered—no registration means an immediate ticket. Then measure the spoiler dimensions—excessive length or width results in vehicle impoundment. Lastly, consider the driver's attitude—cooperation with rectification leads to lighter fines. A key reminder for EV owners: those flashy spoilers with LED strips are more likely to attract attention, especially during nighttime police checks. At a gathering, I met a Tesla owner who installed a glowing spoiler—it only lasted two weeks before getting ticketed twice. For true personalization, opt for clip-on temporary spoilers—install them for track days and remove them for daily driving to avoid hassle.
