🚚 Why Pre-Trip Inspection Matters

Every minute a truck or trailer stays off the road means lost revenue. Professional pre-trip and post-trip inspections reduce breakdowns, avoid legal penalties, and improve delivery reliability. Fleets with strict routines report up to 30% fewer roadside failures.

🔧 Daily Truck Inspection Points

• Engine & Fluids: Check oil, coolant, power steering and AdBlue.
• Air System: Drain tanks, detect leaks, confirm pressure builds to 8+ bar.
• Lighting: Test headlights, indicators, markers and reflectors.
• Tyres: Verify tread depth, pressure and sidewall condition.
• Brakes: Ensure quick air brake response and firm parking brake.
• Cab Instruments: Warning lights, gauges, mirrors and horn must work.

🚛 Trailer Inspection Points

• Kingpin & Fifth Wheel: Safe lock engagement, no cracks, no excessive play.
• Suspension & Axles: Inspect bushings, hangers and air bellows.
• Electrical Lines: Check 7-pin connectors for corrosion and tight fit.
• Landing Gear: Smooth crank operation, adequate lubrication.
• Brake Chambers: No leaks; secure ABS cables and hoses.
• Load Security: Tight straps, twist-locks, chains or container locks.

📋 Weekly or Scheduled Checks

• Torque wheel nuts after tyre service.
• Measure brake lining/drum/disc wear.
• Inspect chassis for cracks and corrosion.
• Test ABS/EBS sensors with diagnostic tools.
• Verify reflectors, ID plates and load indicators.

🧰 Digital Fleet Management Tools

Modern fleets use cloud-based inspection forms connected to telematics. These systems alert workshops instantly when a defect is reported, improving **uptime, compliance and safety**.

🏁 Final Thoughts

Inspection is more than a legal requirement — it’s a frontline defense against costly downtime. Combining driver discipline with digital fleet tools keeps trucks and trailers safe, efficient and road-ready.
