What is a Flat Toll? When is a Flat Toll applied?

Flat Tolls are rare and appear on invoices when either the entry or exit of your trip is not captured by our systems and a sufficient trip history has not been established.

  • For light vehicles without a transponder, a Light Video Flat Toll will apply.
  • For heavy vehicles with a transponder where there are fewer than 10 trips recorded for that transponder over the past 72 days, or more than 25% of trips did not accurately record either the entry or exit point, a Heavy Vehicle Flat Toll will apply.

To help avoid flat tolls, please mount transponders as recommended and when a calculated trip appears on the invoice it will be marked with an asterisk(*).
