Standard Operating Procedure: Daily Vehicle Inspection & Maintenance

This Standard Operating Procedure (SOP) outlines the mandatory daily inspection requirements for all fleet vehicles. Ensuring that every vehicle is checked prior to operation is critical for maintaining safety, regulatory compliance, and vehicle longevity. By systematically identifying mechanical issues, fluid leaks, or safety defects before the vehicle departs, we minimize unplanned downtime, prevent catastrophic mechanical failure, and ensure the safety of our personnel and the public.

Pre-Start Exterior Inspection

• Tires and Wheels: Check tire pressure (visual check for low pressure), inspect sidewalls for bulges or cuts, and ensure tread depth is sufficient. Verify all lug nuts are present and tight.
• Lights and Indicators: Test headlights (high/low beam), turn signals (front/rear), brake lights, and hazard flashers. Replace any burnt-out bulbs immediately.
• Body Integrity: Conduct a 360-degree walk-around to identify new dents, scratches, broken mirrors, or cracked windshields. Report all new damage to the fleet manager.
• Fluid Leaks: Observe the ground beneath the engine and transmission bay for fresh puddles of oil, coolant, or brake fluid.

Under-the-Hood Assessment

• Engine Oil: Use the dipstick to verify the oil level is within the manufacturer’s recommended operating range.
• Coolant Levels: Check the coolant reservoir; ensure levels are at the "Full" line when the engine is cold. Never open a hot radiator cap.
• Brake and Power Steering Fluids: Ensure all translucent reservoirs show fluid levels between the minimum and maximum markers.
• Belts and Hoses: Visually inspect for visible fraying, cracking, or signs of excessive wear on serpentine belts, and look for bulges or leaks in radiator hoses.

Interior and Safety Systems

• Dashboard Indicators: Upon starting the ignition, verify that no "Check Engine," "ABS," or "Airbag" warning lights remain illuminated.
• Braking System: Ensure the parking brake engages firmly and the pedal travel is within normal limits.
• Steering: Verify there is no excessive "play" in the steering wheel or unusual noises when turning the wheel from lock to lock.
• Emergency Equipment: Confirm the presence and expiration date of the fire extinguisher, a stocked first-aid kit, and functional safety triangles/reflective gear.
• Cleanliness: Remove all trash and debris from the cabin to prevent pedal interference and maintain a professional environment.

Pro Tips & Pitfalls

Pro Tips

• Consistent Timing: Perform inspections at the same time each day (e.g., first thing in the morning) to build a reliable habit.
• The "Point and Call" Method: Physically point at each component as you check it; this cognitive engagement significantly reduces the likelihood of skipping a step.
• Photo Documentation: If you find damage, take a high-resolution photo and upload it to the fleet management software immediately.

Common Pitfalls

• The "Normalization of Deviance": Ignoring a minor "ticking" sound or a slow leak because it hasn't caused a breakdown yet. Always report minor abnormalities.
• Rushing: Performing the inspection while distracted. If you are interrupted, restart the inspection from the beginning.
• Visual-Only Inspection: Failing to actually touch or test components (like tires or parking brakes) can hide critical failures that are not visible to the eye.

Frequently Asked Questions

Q: What should I do if I discover a vehicle defect during my inspection? A: Do not operate the vehicle. Immediately tag the vehicle as "Out of Service," notify your direct supervisor, and submit a maintenance request form detailing the specific defect.

Q: How often should I check the tire pressure vs. just looking at the tires? A: While a visual inspection is daily, a pressure gauge check should be performed at least once per week or whenever the vehicle will be used for long-distance travel.

Q: Are there different requirements for electric vs. internal combustion vehicles? A: Yes. While the exterior and interior checks are similar, electric vehicles (EVs) require specific attention to the charging port integrity, cable condition, and high-voltage cable health (look for physical damage to orange-cased wires).
