In Virginia they offer Clean Special Fuel Vehicle license plates for vehicles to access to only certain HOV lanes. For example, I cannot use I-95 EZ Pass for free unless I have 3+ people, but I can use the Dulles Toll Road and a few others that meet the criteria for the IRS for Clean Special Fuel Vehicles.

We need an option to put in the type of playe/access that will route away from tolls, but allow us to use the HOV lanes where it is free. I'm sure this is similar in other states and places.
