How often should passenger vehicles undergo annual inspection?

[LaStephen]

Passenger vehicles are categorized into commercial and non-commercial use. Family cars fall under non-commercial vehicles, which are exempt from inspection for the first 6 years; vehicles older than 6 years require annual inspection; those exceeding 15 years must be inspected every 6 months. Taxis, as commercial passenger vehicles, require annual inspection within the first 5 years, and semi-annual inspections thereafter. Vehicle annual inspection refers to mandatory testing for all registered vehicles with official license plates and registration certificates. It functions as an annual 'health check' based on motor vehicle safety technical standards, helping to promptly eliminate potential hazards, encourage proper maintenance, and reduce traffic accidents - commonly known as vehicle inspection.
