What are the key vehicles in motor vehicle management?

Motor vehicle management primarily focuses on older vehicles and diesel vehicles. Emission Exceedance: Tailpipe emissions failing to meet standards is the most common issue encountered during annual vehicle inspections and also the most penalized. Statistics show that most private vehicles across the country fail to meet tailpipe emission standards during annual inspections. If a vehicle's emissions are found to be non-compliant during random checks, the relevant authorities will temporarily confiscate the vehicle's driving license. The owner must carry out repairs and rectifications within 7 days and can only retrieve the driving license upon presenting a re-inspection compliance certificate. Reasons for Exceedance: Excessive emissions may be caused by the use of poor-quality gasoline, a damaged catalytic converter, a faulty oxygen sensor, or malfunctions in certain sensors near the engine. The normal operation of a car's engine relies heavily on sensors. There are numerous sensors around the engine, such as the oxygen sensor, camshaft position sensor, intake air flow sensor, intake air temperature sensor, and coolant temperature sensor, among others. If certain sensors are damaged, it can lead to the engine malfunctioning.
From my years of experience in long-distance transportation, the absolute priority in vehicle management should be large trucks. These massive vehicles are slow to turn and prone to causing traffic jams or even major accidents. I once witnessed an overloaded truck overturning on the highway, blocking the entire section for four hours and making rescue efforts extremely difficult. Overloading is also a widespread issue—some drivers cram in extra cargo for higher profits, risking brake failures. Traffic authorities must strictly enforce freight standards, install fatigue-driving monitoring systems, and increase checkpoints. Personally, I believe enhancing driver training and regular vehicle safety inspections are key, as they can significantly reduce fatal accident rates and make roads smoother and safer.
