ETC FAQ's
What products does Sirit offer to the tolling industry?
Sirit is a supplier of toll transponders compliant with the California Department of Transportation (CalTrans) Title 21 standard for high speed, open lane electronic toll collection and traffic management applications. Some customers have successfully integrated and used the Sirit IDentity Flex series for an economical solution for low speed or stop and go applications.
Can I use my tag with other tags in the same vehicle?
Your tag will not interfere with the use of an IDentity Flex tag, however, only one Title 21 compliant tag type can be used in a single vehicle without potential of interference. Multiple tags should be mounted at least 6" apart.
How can I store my tag if I do not want it to be read?
Your toll agent usually provides metallized shielded plastic storage bags for use to prevent your tag from beind read (if you have multiple tags in the vehicle)
Why does my tag beep sometimes and not others?
The tag beeps when it receives an acknowledgement signal from the lane equipment that it has been successfully read. Not all toll operations implement an acknowledgement signal.
Will my toll tag work in other areas or states?
Toll tags are the property of the toll authority. Some agencies, particularly in Southern California have interworking relationships, whereby a toll tag from one agency can be read by another. Toll tags used in other parts of the United States are based on proprietary technology and are not compatible with Title 21.
How does a toll tag work?
A transmitter in the lane sends a signal to wake up the tag in the vehicle which responds by reflecting the energy back to the lane receiver. This coded information is detected by the lane computer and verified to the unique account information for your vehicle.
Will my tag interfere with my car electronics?.
No, the tag is not a transmitter and will not affect your car electronics.
Does Sirit have an alternative to the windshield tag?
Yes, Sirit manufactures a bumper mounted tag specifically for external applications. This tag secures with tamper resistant stainless screws to the license plate and includes a special key tool required for removal.
