Enrolling a Trailer in Toll Tracking

Enrollment is the one-time setup that lets TrailerBase capture a trailer's tolls and bill them back to renters automatically. You do it once per trailer.

Prerequisite: License Plate + Plate State

Toll tracking matches tolls to your trailers by license plate and plate state, so a trailer must have both set before it can be enrolled. Open the trailer (Trailers → the trailer → Edit), fill in License Plate and Plate State (the 2-letter US state, e.g. TX), and save. There is no transponder or provider account to set up.

Enrolling

Go to Tolls → Enrollments. In the enrollment control, pick the trailer from the dropdown and click Enroll. Trailers still missing a plate or state are greyed out and labelled needs plate + state — set those first. TrailerBase registers the trailer with the toll provider behind the scenes using its plate and state.

What Happens Next

Once a trailer is enrolled:

  • Tolls sync automatically — new toll events flow into your Tolls dashboard. Real-time events arrive within minutes, and a reconciliation sync runs regularly as a safety net so nothing is missed.
  • Tolls attach to the rental — each toll is matched to whichever reservation had the trailer when the toll occurred, using the pickup and return window. A toll that lands while no one had the trailer out is parked in the Review queue for you to assign or waive — it is never billed to the wrong renter.
  • Renters are billed on the invoice — see Billing Tolls to Renters.

Changing or Removing an Enrollment

Every enrolled trailer is listed in Tolls → Enrollments. If you sell or retire a trailer, remove it there. If a trailer's plate changes, update the plate on the trailer and re-enroll.
