What is the difference between PM-A, PM-B, and PM-C services in trucking?

PM-A (Dry Inspection) occurs every 5,000-10,000 miles covering safety checks, fluid top-offs, tires, and lights. PM-B (Wet Service) occurs every 15,000-30,000 miles including full oil and filter changes, lube, and driveline inspection. PM-C (Comprehensive) is an annual or 100,000-mile complete teardown inspection aligning with DOT annual requirements.

How does Exspeedite TMS automate fleet maintenance schedules?

Exspeedite automatically pulls live odometer telemetry from Samsara, Motive, and Geotab, scheduling PM service work orders before limits are breached and locking uninspected equipment from dispatch.

Commercial Fleet Preventive Maintenance PM-A/PM-B Schedule Optimizer

The definitive fleet maintenance engineering manual: automate mileage-triggered PM services from live ELD telematics, manage internal shop mechanics with automated work orders, and eliminate catastrophic roadside service calls.

Live Telematics Odometer Sync

No more guessing when a tractor needs service. Exspeedite syncs daily odometer telemetry directly from Samsara, Motive, or Geotab, queuing PM work orders as mileage targets approach.

Shop Mechanics TimeClock

Track shop labor hours and parts inventory down to the specific work order: oil filters, brake drums, air lines, and tires are deducted from stock and billed to vehicle unit GL accounts.

90-Day Trailer & Annual DOT

Never let a trailer cross state lines with an expired annual inspection. Exspeedite flags equipment due for periodic 90-day dry checks or annual DOT inspections directly on dispatch boards.
