How many years before a car requires two annual inspections?

[RebeccaLynn]

Small cars require two annual inspections after 15 years. Below are the relevant details: 1. Regulations: Small and micro non-commercial passenger vehicles (i.e., private cars) must undergo inspection once every 2 years within the first 6 years; after 6 years, once every year; after 15 years, twice every year, with emissions testing conducted on the same dates as the annual inspections. For new cars, the inspection validity date is already marked for 2 years from the month corresponding to the registration date. 2. Required documents: Materials needed for the annual vehicle inspection include the car itself, the vehicle registration certificate (both original and duplicate copies), and a valid third-party liability insurance policy with at least 1 year of coverage. For installment payments without the original insurance policy, a copy of the insurance policy (stamped by the insurance company), an insurance card, and identification documents along with their copies are required.
