How often should a 2013 vehicle undergo annual inspection?

[LeJuliette]

For a 2013 passenger car, the inspection frequency is every two years within the first six years, and annually thereafter. The vehicle inspection schedule is as follows: Non-commercial passenger cars: New vehicles within six years are exempt from on-site inspection but must apply for an inspection mark every two years. Privately owned cars registered after September 2012 that meet the conditions can enjoy the exemption policy; vehicles aged 6 to 15 years must undergo on-site inspection once a year, while those over 15 years must undergo inspection every six months. Commercial passenger vehicles: Inspections are required once a year within the first five years, and every six months thereafter. Trucks and large or medium-sized non-commercial passenger vehicles: Inspections are required once a year within the first ten years, and every six months thereafter.
