What are the contents of the three daily vehicle inspections?
3 Answers
The contents of the three daily vehicle inspections are pre-trip inspection, mid-journey inspection, and post-trip inspection. These three daily inspections can effectively ensure vehicle safety. Below is a detailed introduction about automotive safety: 1. Overview: Automotive safety mainly consists of two major aspects: active safety and passive safety. Active safety refers to the ability to control the vehicle as smoothly as possible. Whether braking and accelerating in a straight line or steering left and right, the operations should be as stable as possible to avoid deviating from the intended path and without affecting the driver's visibility and comfort. 2. Others: Automotive safety technology covers an increasingly wide and detailed range, developing towards integration, intelligence, systematization, and universalization. Strictly controlling speed during night driving is the fundamental measure to ensure safety.
Hey, long-haul drivers, let’s talk about the daily three-check routine we all do! Pre-trip inspection is the most crucial: walk around the vehicle to check if all four tires have proper pressure and no cuts or bulges, pop the hood to ensure engine oil, coolant, and brake fluid levels are adequate with no leaks—running dry mid-trip would leave you stranded. Test all lights—brake lights, turn signals, headlights—missing one could get you fined; also pump the brakes to feel their firmness and listen for normal air brake exhaust sounds. On the road, pull over every 2-4 hours for key checks: touch the wheel hubs for excessive heat (dangerous if overheating), tap tire lug nuts with a hammer to confirm tightness, and look under the vehicle for any oil, fluid, or air leaks. After a long day, never skip post-trip duties: recheck for leaks, thoroughly inspect brake components and belt tension, rinse off mud from the undercarriage, and pick out stones lodged in tire treads. That extra half-hour might just save your life on the next trip!
We mechanics know best where problems are likely to arise. The three daily inspections are not just formalities! Before departure: Listen for any abnormal noises when starting the engine, turn the steering wheel fully left and right to check for oil leaks or looseness in the power steering pump and tie rods, ensure the windshield washer fluid is topped up, and adjust the rearview mirror angles—these are the safety basics. Mid-journey checks cannot be skipped: After driving about a hundred kilometers, check the wheel hub temperature (press the back of your hand against it; if it's unbearably hot, there's definitely a problem). For semi-trailers, pay special attention to the air hose connections and whether the trailer brake chamber push rods have retracted, and feel if the universal joints on the drive shaft are leaking oil or overheating. Post-trip inspections must be thorough: Pry out large stones stuck in the tire treads (especially for run-flat tires), check under the air compressor and oil pan for any signs of oil or water leaks, and ensure the U-bolts on the leaf springs are not loose—particularly for heavy trucks, as a single broken leaf spring can cause major trouble. Spend 10 minutes on these checks, and they'll keep you safe for the day.
