What is a Missing Plate alert?

A Missing Plate alert is thrown when one of your asset’s receives a license plate toll, but there is no license plate number assigned to the asset in tollogic™.

Toll Collection Context

Toll agencies collect tolls by reading the toll transponder installed in an asset. If the transponder does not read, for any reason, the agency will capture an image of the asset’s license plate, find the asset in a state or proprietary database, and issue an invoice for the toll. This toll invoice, known as a license plate toll (LPT), may appear on your regular electronic toll invoice or mailed as a physical letter.

Because LPTs take more time and resources to issue, they are typically 25% more expensive than transponder tolls. Regional premiums vary for LPTs.

Please keep the toll transponder and license plate together on every asset to prevent license plate tolls and toll mismatches. If a transponder or license plate needs to be moved or removed, please update all relevant details within tollogic™ and your toll manager.

Missing Plate Alert

When an asset incurs a license plate toll (LPT), tollogic™ will attempt to match the license plate on the toll to a license plate in our database. If no license plate matches, tollogic™ will then attempt to match the LPT details to telematics from all assets in your fleet. If an asset within your fleet was located at the same toll plaza at the same time as the LPT, but the asset has no license plate assigned in tollogic™, then the asset will trigger a Missing Plate alert.

Next Action

If an asset has triggered a Missing Plate alert, please verify the license plate and transponder details on the asset. If the license plate on the LPT should be added as a license plate on this asset, please update the license plate as such in tollogic™.
