Fleet Preventive Maintenance
Stop breakdowns before they start. Scheduled mobile PM service and DOT inspections that keep your whole fleet road-legal and rolling — on your yard, on your timetable.
On-site, done right.
Reactive repair is always more expensive than scheduled maintenance. A missed oil change interval leads to accelerated engine wear. An unchecked brake adjustment leads to a roadside inspection failure. An overdue DOT Annual Inspection leads to a vehicle placed out of service at a scale. Interstate Fleet Services builds fleet preventive maintenance programs around the vehicles, intervals, and compliance requirements of your specific operation — and we execute them on-site so your units stay in your yard and on your routes.
IFS fleet PM services cover the full scope of scheduled maintenance for commercial trucks and trailers: engine oil and filter changes, fuel filter service, coolant system inspection and service, air filter replacement, differential and transmission fluid checks, brake inspection and adjustment, tire inflation and tread depth measurement, lighting and electrical checks, belt and hose inspection, and lubrication of all grease points. We also perform DOT Annual Inspections and pre-purchase inspections, issuing the required documentation when the vehicle passes.
For fleets with multiple units, we maintain service records that track PM history, upcoming interval milestones, inspection dates, and any deferred repairs flagged during the service visit. This gives fleet managers a live picture of the maintenance status of their equipment without relying on driver-reported symptoms alone. Consistent, documented PM is also the foundation of any FMCSA compliance audit defense — inspectors expect to see it, and carriers that cannot produce it face consequences.
What's included
- Scheduled PM programs
- DOT & annual inspections
- Oil, filters & fluids on-site
- Fleet-wide service history
Signs it's time to dial.
- A truck or trailer is approaching or has exceeded its scheduled oil change, filter, or fluid service interval
- The DOT Annual Inspection is coming due and the carrier wants the inspection performed at their facility rather than a shop
- A unit has been flagged in a roadside inspection report and the carrier needs a documented corrective PM before the vehicle returns to service
- A newly acquired used unit needs a pre-purchase or pre-fleet inspection to assess its true mechanical condition before acceptance
- A driver has noted minor items — slow air build, a light out, a soft brake pedal — that do not rise to an emergency but should not wait for the next PM appointment
- The fleet manager wants to transition from reactive repair to a structured scheduled PM program and needs a baseline inspection of all units
One call to back on the road.
Schedule & Dispatch
Call 1-888-589-9281 to schedule a PM visit or set up a recurring PM program for your fleet. We work around your operational schedule to minimize downtime — including early morning and weekend PM windows — and arrive at your yard or designated location with all required fluids, filters, and inspection tooling.
Systematic Inspection
The technician follows a standardized inspection checklist that covers every system required under FMCSA Part 393 and Part 396 plus any fleet-specific items requested. Brake measurements, tire readings, fluid levels and condition, belt tension, lighting function, and chassis lubrication are all documented with actual measurements, not just pass/fail checkboxes.
Service Execution
Scheduled service items are performed: oil drained and refilled to spec with the correct viscosity, filters replaced, grease points serviced, brakes adjusted, air dryer cartridge replaced if due, and any additional items authorized by the fleet manager. Parts and fluids used are documented on the service ticket.
Findings Report & Record Update
Before leaving, we walk the fleet manager or driver through any conditions flagged during the inspection that were not part of the scheduled PM — items to monitor, items to address at the next service, and any conditions that require prompt attention. The completed service record is provided and filed in the unit's maintenance history.
Fleet Maintenance questions.
Can IFS perform DOT Annual Inspections on-site at our terminal?
Yes. IFS qualified inspectors perform DOT Annual Inspections at your location for both trucks and trailers. We issue the required inspection report and, when the vehicle passes, apply the annual inspection sticker. Having the inspection done on-site eliminates the downtime and cost of moving vehicles to an outside facility.
Does IFS maintain service records for fleet customers?
Yes. We track PM history, inspection dates, odometer readings at service, parts used, and any deferred repair notes for fleets that are on a recurring PM program with us. This documentation is available to fleet managers and is formatted to support FMCSA compliance reviews.
How does IFS handle deferred repairs found during a PM inspection?
Any condition found during a PM that is beyond the scope of the scheduled service is documented on the inspection report with a severity classification — monitor, address at next PM, or address before the unit returns to service. The fleet manager makes the authorization decision; we do not make unilateral repairs beyond the agreed service scope.
Can IFS set up a PM schedule for a fleet of 20 or more units?
Yes. We build custom PM programs for fleets of all sizes, from a handful of units to large multi-terminal fleets. Contact us at 1-888-589-9281 to discuss your fleet size, equipment types, and mileage or engine-hour intervals so we can build a program that fits your operation.
What is the advantage of on-site fleet PM versus sending units to a shop?
On-site PM eliminates drive time to and from the shop, shop queue wait time, and the administrative overhead of managing unit scheduling across multiple service providers. The truck stays in your yard until it is needed, the PM is performed by a known IFS technician, and the service record is in your hands the same day — not mailed a week later.
