Drivers Must See How To Quickly Determine The Vehicle's Status While Driving

Drivers must pay attention to how to quickly determine the status of vehicles on the road. Long distance freight road conditions are complex, and overseas line maintenance resources are limited. Many breakdowns on the way are caused by minor faults that were not detected in a timely manner. Drivers can master simple judgment methods while driving, and can detect abnormal signals in advance by looking, listening, feeling, and smelling, reducing downtime losses and ensuring transportation safety. During the driving process, the dashboard is the first information window, so there is no need to stare at the screen. It is crucial to pay attention to the water temperature, oil pressure, air pressure, and various warning lights in the spare time. The continuous increase in water temperature is likely due to hidden dangers in the cooling system; Low oil pressure can easily cause engine stalling when driving continuously; If the air pressure drops too quickly, be alert to air leakage in the air circuit, which directly affects braking safety. Don't take chances when the alarm light is on. Distinguish between yellow warning and red emergency warning. When the red light is on, prioritize choosing a safe area to pull over and do not forcefully continue on the road. Secondly, by listening to changes in sound, each truck has its own familiar operating sound, and any new or unusual noises should be taken seriously. When stepping on the brake, there is a sharp metal friction sound, which is mostly due to severe wear of the brake pads; Continuous buzzing during turning or constant speed driving may be due to abnormal wheel hub bearings; When there is a clicking sound when shifting gears, pay attention to the transmission and clutch components; There is continuous abnormal noise coming from the chassis. Check if the suspension and fasteners are loose. Abnormal noise varies with vehicle speed and load, often corresponding to different parts of the fault. Record the conditions under which abnormal noise occurs to facilitate subsequent maintenance and troubleshooting. Another thing is to feel the feedback from the vehicle. The steering wheel feels stable during normal driving. If there is deviation or shaking, priority should be given to checking the tire pressure and dynamic balance. It may also be due to an increase in steering clearance. The brake pedal becomes softer, the stroke becomes longer, and the braking response slows down, which is a high-risk signal for the braking system; Heavy load acceleration is noticeably weak, and fuel consumption suddenly increases, which may be due to intake blockage, fuel supply or turbine problems. The body shakes inexplicably while driving, and it is also necessary to distinguish whether it is a tire problem or an unbalanced transmission shaft. Smell is also an important clue for judgment. If you smell a burnt smell, it is mostly due to brake pad dragging or clutch slipping; The diesel smell is strong, and the oil pipe joint should be checked for leakage; If you smell the smell of burning wires, immediately cut off the power and check the wiring to avoid the risk of fire. If any abnormalities are found during driving, do not force yourself at high speeds, slow down steadily, choose a safe area to park, conduct a simple appearance inspection, record the fault symptoms and synchronize them with the fleet maintenance personnel. Overseas long-distance driving, the driver's predictive ability is the key to reducing operating costs. Developing the habit of constantly sensing the vehicle's status and controlling faults in the early stages can not only protect the vehicle, but also maintain the bottom line of driving safety.
