Who is responsible for performing the secondary maintenance of vehicles?

[MacLeo]

Maintenance enterprises. The following is relevant information about vehicle maintenance: 1. Primary maintenance: Primary maintenance is a vehicle maintenance operation performed by maintenance enterprises. In addition to daily maintenance operations, its main tasks include cleaning, lubrication, and tightening, as well as inspecting safety components such as brakes and controls. 2. Secondary maintenance: Secondary maintenance is a vehicle maintenance operation performed by maintenance enterprises. In addition to primary maintenance operations, its main tasks include inspecting and adjusting safety components that are prone to wear or deformation after prolonged use, such as steering knuckles, steering arms, brake shoes, and suspensions, as well as dismantling and inspecting tires for rotation.

I've been driving trucks for over a decade and always get my secondary maintenance done at certified repair shops. Only facilities with Class I or Class II maintenance qualifications can perform this work, and they must be registered with the transportation authorities. I remember once trying to save money by going to a roadside shop, and they didn't adjust the brake system properly - it nearly caused an accident. Now I always go to my trusted shop. They have all the necessary equipment, and their experienced mechanics thoroughly inspect the chassis, brakes, and lighting systems with diagnostic tools. Finally, they issue a maintenance compliance certificate that gets uploaded to the transport management system. This kind of professional maintenance is far more complex than basic servicing - it's directly related to driving safety, so you really can't cut corners by going to small unqualified shops.

Our repair shop performs secondary maintenance on over a dozen vehicles daily, which must be carried out by certified technicians. From inspecting the brake system to measuring exhaust emissions, every step follows standardized procedures. We use wheel alignment equipment to check chassis data and diagnostic computers to read engine parameters, finally completing maintenance records. I remember last year when a ride-hailing vehicle had its driveshaft issue detected early during our maintenance, preventing an accident three months later. Unqualified shops can't even operate lift equipment properly, let alone perform such detailed inspection items.

Transportation regulations clearly stipulate that secondary maintenance must be performed by qualified repair enterprises. Such enterprises must meet three conditions: having a registered business license, being equipped with professional testing equipment, and employing technicians with vocational qualification certificates. The main inspection items involve critical systems such as steering, braking, and transmission. Upon completion, a compliance certificate must be issued and data uploaded. Last time I accompanied a friend for annual inspection, they were required to undergo supplementary inspection due to missing maintenance records. Regular professional maintenance actually helps vehicle owners avoid safety hazards.
