The Vehicle Inspection and Maintenance SOP

Purpose

Define how work vehicles get inspected before use and maintained on schedule. A standard operating procedure (SOP) is the written, repeatable process everyone follows the same way, so vehicle safety does not depend on which driver is behind the wheel. A fleet is the largest safety exposure most shops carry: a truck with bad brakes or a bald tire is a crash and a lawsuit waiting for the wrong morning. A daily walk-around catches the defect in the yard instead of on the highway, and scheduled maintenance keeps small problems from becoming breakdowns that strand a tech and blow up the day's schedule.

Scope

Applies to every company-operated vehicle:

• Service trucks and vans
• Trailers and towed equipment
• Any vehicle a technician drives for company work

Covers the daily driver inspection and the scheduled preventive maintenance (PM) cycle. Excludes personal vehicles not used for company work.

Roles and responsibilities

Safety rule that overrides everything below

If the inspection finds a defect that makes the vehicle unsafe to drive, the vehicle is parked and tagged out of service before any other step. It does not get driven "just to the shop" or "just this one call." An out-of-service condition includes any of:

• A brake problem: soft pedal, grinding, pulling, or a warning light
• A tire that is bald, cut, bulging, or badly underinflated
• Steering that is loose or wanders
• Lights out that are required to drive legally
• A leak of brake fluid, fuel, or a steady drip of any fluid
• A load or rack that is not secure

Report it, get a replacement vehicle, and let the coordinator route the repair. Diagnosis and scheduling come after the truck is off the road, never before.

Procedure

Step 1: Daily walk-around before the first drive

The driver circles the vehicle before leaving the yard and checks:

• Tires: tread, obvious damage, and pressure that looks right
• Lights: headlights, brake lights, turn signals, hazards
• Fluids: oil, coolant, and any puddle under the vehicle
• Brakes: firm pedal, no warning light, a working parking brake
• Glass and mirrors: clear view, no blocking crack
• Load security: ladders, racks, and cargo tied down

Step 2: Check the cab and safety gear

Inside, confirm the horn, wipers, and seatbelts work and that the required safety items are present: fire extinguisher charged, first-aid kit stocked, warning triangles or flares aboard. A missing extinguisher is a defect, not an optional extra.

Step 3: Log the inspection and any defect

Record that the inspection was done and note every defect found, even a minor one. A written log does two things: it proves the inspection happened if a vehicle is ever in a crash, and it feeds the coordinator a running defect list. A defect noticed but never written down is a defect that gets forgotten until it fails.

Step 4: Route defects by severity

• Unsafe: the vehicle is already parked per the safety rule above; the coordinator schedules the repair now.
• Needs attention but drivable: logged and scheduled into the next PM or sooner, driver informed.
• Cosmetic: logged for the batch fix.

Step 5: Follow the scheduled PM cycle

Preventive maintenance runs on the interval set by mileage, engine hours, or time, whichever comes first for that vehicle. Standard PM covers oil and filters, brake inspection, tire rotation and condition, belts and hoses, and fluids. The coordinator tracks each vehicle's next-due point and pulls it in before the interval passes, not after a warning light.

Step 6: Record every service

Each PM and repair is recorded against the vehicle: what was done, when, at what mileage, by whom. The service history is what tells you a vehicle is becoming a money pit worth replacing and is the backup for warranty and resale.

Records and retention

Keep daily inspection logs and the full service history for each vehicle. Inspection records in particular matter if a vehicle is ever involved in an accident or a regulatory check.

Common failures

• Skipped walk-around. The defect that was in the yard is found on the road.
• Driving an unsafe vehicle "just this once." The one time is the time it fails.
• Defects noted verbally, never logged. They are forgotten until breakdown.
• PM run on breakdown, not schedule. Reactive repair costs more and strands techs.
