How many years does it take for a sedan to require two annual inspections?

[OJeremiah]

Commercial passenger vehicles over 5 years old and small/mini non-commercial passenger vehicles over 15 years old require two annual inspections. Timeframe: For passenger cars and blue-license-plate minivans: within the first six years after initial registration, inspections are required every two years; after six years, annually; after ten years, once annually; and after fifteen years, twice annually. For trucks: annual inspection after registration, and twice annually after ten years. Regulations: If a vehicle is found by traffic police to have not undergone annual inspection, the owner may face fines or vehicle impoundment. Additionally, in insurance contracts, vehicles not timely inspected are considered unqualified, and no claims will be paid in the event of an accident.
