Preventive Maintenance Scheduler for Owner Operators
Track service intervals by odometer and the annual DOT inspection by date, with projected due dates.
Your Truck
Miles per week is used to estimate the calendar date each service will come due.
Annual DOT Inspection
Every commercial motor vehicle needs a periodic inspection at least every 12 months (49 CFR 396.17). It is based on the date, not mileage.

Intervals are typical starting points, not manufacturer specs — modern engines with extended-drain oil and severe-duty use can differ a lot. Change any interval to match your engine maker's schedule. Your entries are saved in this browser only.

How often does a semi truck need preventive maintenance?
A commercial truck needs maintenance on three schedules at once: daily pre-trip and post-trip checks, service by mileage or time (oil, filters, grease), and the annual federal inspection. FMCSA requires an inspection at least once every 12 months, covering brakes, steering, lights, tires and other safety parts. Keep the inspection report for 14 months from the date of the inspection.
- Do a pre-trip and post-trip check every day the truck runs. Check brakes, lights, tires and coupling devices.
- Follow your engine maker's service schedule for oil, filters and fluids. This varies by engine and duty cycle.
- Book the annual federal inspection every 12 months per truck, and keep the report on file.
- Track mileage-based items like brakes and tires apart from calendar items like the annual inspection. They run on different clocks.
- Keep maintenance records for 1 year where the truck is housed or maintained, and for 6 months after it leaves your control (49 CFR 396.3).
| Clock | Frequency | Rule |
|---|---|---|
| Pre-trip / post-trip inspection | Every day of operation | 49 CFR 396.13, 396.11 |
| Manufacturer service intervals | By mileage or engine hours, varies by engine | Set by the manufacturer, not federal law |
| Periodic (annual) inspection | At least once every 12 months, per vehicle | 49 CFR 396.17 |
Mileage-based service intervals (oil changes, filters) are set by each engine manufacturer and vary by engine family and duty cycle, so follow your truck's own service manual for those rather than a generic number.
