How many years later does a sedan require biannual inspections?

[CatherineLynn]

Vehicles over 15 years old require inspections twice a year. Below are the relevant details: 1. Passenger transport vehicles: Annual inspection within 5 years; every 6 months after exceeding 5 years. 2. Trucks: Large and medium-sized non-passenger transport vehicles require annual inspection within 10 years; every 6 months after exceeding 10 years. 3. Small and mini non-commercial vehicles: Passenger vehicles require inspection every 2 years within 6 years; annual inspection after exceeding 6 years; every 6 months after exceeding 15 years. 4. Scrap age: Vehicles exceeding the scrap age cannot be transferred (sold), but can still be used; for sales, the vehicle's scrap certificate can be obtained from the DMV (to deregister the vehicle's records) before proceeding with the sale.
