Can Modified Springs Pass the Annual Vehicle Inspection?
2 Answers
Modified springs can pass the annual vehicle inspection as long as they do not alter the vehicle's structure or characteristics. Annual Inspection Documents: Original "Motor Vehicle License Plate Application Form" (signed by the authorized person for company vehicles, signed by the owner for private vehicles), Motor Vehicle Compulsory Traffic Accident Liability Insurance Certificate, copy of the vehicle and vessel tax payment or tax exemption certificate, original Motor Vehicle Safety Technical Inspection Certificate, original "Motor Vehicle Driving License". Annual Inspection Time Regulations: The annual inspection time for vehicles is determined by the date of new vehicle registration. For example, if the initial registration date on the Motor Vehicle Driving License is June 2015, then the annual inspection time is every June. Additionally, according to Article 40 of the newly revised "Motor Vehicle Registration Regulations", vehicle owners can apply for the inspection compliance mark at the local vehicle management office up to three months before the expiration of the vehicle inspection period. This means that vehicles due for inspection in June can undergo the annual inspection in April, May, or June.
From the experiences shared by some car owner friends, modifying springs is indeed not easy to pass the annual inspection. I've seen many people who modified their suspensions, especially those who lowered the vehicle height or replaced them with stiffer springs, only to fail the inspection at the DMV. This is because the annual inspection has clear regulations, testing the stability of the suspension system and whether the vehicle height meets the standards. If the car is too low after modification, the airbags may also not deploy properly. I remember one time when Old Zhang's car had to be repaired several times before barely passing. Personally, I suggest that if you want to modify, be sure to have a professional auto repair shop evaluate the suspension setup to ensure the test data meets the standards. Also, pay more attention to tire wear and light alignment in daily use, as these small details can accumulate to improve the pass rate. After all, the annual inspection is no small matter—it's about road safety, and there's no room for carelessness.
