Daily Vehicle Pre-Trip Inspection

Purpose

Define the daily pre-trip vehicle inspection protocol for service-vehicle fleets. A 5-minute inspection catches the issues that cause roadside breakdowns, accidents, and DOT violations. Field-service vehicles are the office mobile - when one is down, a tech's entire day is canceled + customers are rescheduled. The discipline pays back tens of times its cost in avoided downtime.

Scope

Applies to:

• All company-owned service vehicles (vans, trucks)
• Vehicles operated by employees (personally-owned + used for business)
• Trailers + towed equipment

Excludes commercial DOT-regulated fleets (federal DOT inspection standards apply; this SOP is the underlying discipline + can be extended for DOT compliance).

Responsibilities

• Driver / technician completes inspection daily before first use
• Fleet manager reviews submitted inspection forms weekly
• Service manager addresses any flagged issues promptly

Procedure (5 - 7 minutes)

1. Walk-around inspection (exterior):

• Tires: visual condition + pressure (any visible underinflation; sidewall damage)
• Lights: headlights, brake lights, turn signals, hazards (have a partner verify rear lights OR use a reflective surface)
• Glass: clean + free of cracks that affect view
• Mirrors: clean + properly positioned
• Body damage: any new damage since previous use (photograph if found)
• License plates: visible + properly mounted
• Registration + insurance card: in glove box + current

2. Engine compartment (when cool, before first start):

• Engine oil level (dipstick check)
• Coolant level (visible reservoir)
• Power steering fluid
• Brake fluid level
• Windshield washer fluid
• Visible leaks under the vehicle

3. Interior + cab (driver area):

• Mirrors adjusted
• Seat belt operational
• Horn functional
• Wipers + washers operational
• Dashboard warning lights (key in ON position; verify lights illuminate then go off when started)
• Air conditioning + heating operational
• Defroster operational

4. Cargo / equipment area:

• Tools + parts secured (loose items in cargo area become projectiles in a crash)
• Hazmat materials (if carrying - pool chemicals, refrigerant cylinders, etc.) secured + ventilated
• Truck-bed cover or tonneau secured
• Trailer connections (if applicable) - pin, chains, electrical, brake controller

5. Start + first-mile check:

• Start engine + listen for unusual sounds
• Watch for warning lights persisting
• Test brake pedal (should be firm; not spongy)
• Test parking brake
• Drive < 5 mph in parking lot: brake test, steering response, listen for unusual sounds

Acceptance Criteria

• All inspection items pass
• Any failures documented + addressed before driving
• Inspection form submitted (paper OR digital app)
• Vehicle insurance + registration current + accessible

Common findings

• Low tire pressure - most frequent finding; underinflated tires cause blowouts + reduce fuel economy
• Burnt-out bulb - quick fix; major liability if missed
• Fluid leaks - small leaks become roadside breakdowns
• Damaged windshield - chips become cracks; cracks become DOT issues + liability
