Do I have to mount my FasTrak transponder on my windshield?

Yes. FasTrak drivers must have a transponder mounted to their vehicle's windshield.  Transponders make it easier for tolling agencies to charge the correct toll to the appropriate vehicle automatically, resulting in faster processing times with higher levels of accuracy. State law requires a transponder to be in the vehicle or valid license plates properly mounted to the vehicle. See CA Vehicle Code section 23302.
