Preventive fleet maintenance checklist

Before you use it

Assign every check to a role and record the date, odometer and result.
A failed safety item should create an action, not disappear inside a comment.
Schedule by both date and distance when either one can trigger service.
Manufacturer guidance and current local law always override a generic checklist.

Daily or pre-trip checks

The driver is closest to the vehicle and often sees a defect first. Keep the pre-trip check short enough to complete consistently, with a clear rule for taking an unsafe unit out of service.

Tyre condition, visible damage and obvious pressure loss
Headlights, brake lights, turn signals and warning lights
Brake response, steering feel and unusual noise
Leaks under the vehicle and visible fluid levels
Mirrors, windscreen, wipers, horn and seat belts
Required safety equipment for the country and vehicle use
Odometer and any dashboard fault message

Weekly checks

A supervisor or maintenance owner should confirm items that need a little more time or a consistent measuring method.

Tyre pressures, tread depth and uneven wear
Engine oil, coolant, brake fluid and washer fluid
Battery terminals, corrosion and secure mounting
Belts, hoses and visible wiring damage
Cab cleanliness, load restraints and body damage
Emergency kit completeness and extinguisher condition

Monthly fleet review

Monthly control combines vehicle condition with records. It is where isolated defects become patterns and where upcoming work is booked before it becomes downtime.

Compare actual odometer with the fleet record.
Review open defects and repeated issues by vehicle.
Confirm the next date- and distance-based service triggers.
Check licence, insurance, inspection, tax and operating-document expiries.
Review fuel efficiency and sudden changes against the unit’s own baseline.
Confirm recalls or manufacturer service campaigns.

Mileage- or hour-based service

Use the manufacturer’s interval for the exact model, powertrain and duty cycle. Record parts, labour, supplier, cost and the odometer or engine hours at completion so the next trigger is based on evidence.

System	Typical service decision
Engine and filters	Oil, oil filter, air filter and fuel filter at the specified interval
Brakes	Pad, disc, drum, line and fluid inspection; replace by measured condition
Tyres	Rotation, alignment, balancing and replacement from wear and damage
Cooling and drivetrain	Fluid, hose, belt, transmission and differential work per schedule
Electric vehicles	Tyres, brakes, coolant, 12 V system and battery-health checks per manufacturer

Annual and regulatory controls

Create a separate due date for every legal or contractual obligation. Do not hide regulatory renewals inside a general annual-service task: different owners, evidence and consequences usually apply.

Mandatory technical or emissions inspection where applicable
Insurance and vehicle-registration renewal
Road tax, operating permit or carrier registration
Driver-licence and category validation
Safety-equipment certification or replacement
Full policy and checklist review after regulatory changes

Close the loop on every defect

A checklist only reduces risk when a failed item becomes owned work. Record severity, the person responsible, the due date and whether the vehicle can operate. When completed, attach the service evidence and update the odometer. Review recurring failures by vehicle, part and supplier rather than treating each one as new.
