A motorcyclist may not place a toll road transponder:

There are five locations where it is permissible to place a transponder or other electronic toll payment device, provided that toll readers can detect it. A transponder may be placed in a motorcyclist's pocket, inside a cycle net draped across the gas tank of the motorcycle, on a license plate device, in a storage compartment on the motorcycle, or on the windshield of the motorcycle.
