How often should commercial vehicles undergo annual inspections?

[McBrandon]

New regulations for commercial vehicle inspections in 2021 stipulate: Passenger vehicles for commercial use must be inspected once a year within the first 5 years; those over 5 years old require inspection every 6 months. Below are the relevant regulations for other vehicles: Non-commercial passenger cars: Including non-commercial passenger cars, small and micro non-commercial passenger vehicles, and non-commercial small and micro buses with 7-9 seats (excluding minivans) are included in the exemption range, exempt from on-site inspections for the first 6 years, only requiring an inspection mark application every two years. Medium and large vehicles: Trucks and large, medium-sized non-commercial passenger vehicles must be inspected once a year within the first 10 years, and every 6 months for those over 10 years old.
