How it works
When PTO is engaged, the truck's engine powers non-driving equipment. Fuel consumed during PTO engagement is not used for highway propulsion and, in many states, is eligible for a fuel tax refund. ELDs capture PTO engagement via the engine bus.
Who uses it
Vocational carriers — concrete mixers, dump trucks, garbage, cranes, boom trucks, and any truck with auxiliary equipment. Also refrigerated carriers tracking reefer unit runtime.
Why it matters
PTO hours affect IFTA refunds, accurate cost-per-mile calculations, and customer billing on equipment-hour jobs. Miscategorizing PTO fuel as highway fuel leaves money on the table.
In Rig Terminal
Rig Terminal captures PTO hours from the engine bus via the ELD, separates PTO fuel for IFTA reporting, and surfaces auxiliary runtime per truck.
