Hiding Your FasTrak, EZ-Pass, or Other Toll Tag in Your Car

Step 8 Testing

This part is where it is important to save the casing if you disassembled the tag, and where those who did come out ahead.
When you've got your tag placed, you should test it to make sure it works.

To test it, go ahead and drive to your local bridge or toll road, and if you have disassembled your FasTrak, hold the empty case (closed, so it looks like it is not empty) to your window as you drive through. If you have placed the tag in a place where the signal can reach it, your license will be photographed and if they do not see that you have FasTrak (either by license plate # or by looking at the window of the car) they might send you a ticket. By holding up the FasTrak tag case, they will just think that it didn't get signal that one time, and that the device does work. (Toll tags loose signal sometimes, and if your car is registered as having a toll tag, you won't be charged)

Once you've tested your new location and you know that it works, you can save the case, or use it for something else. You don't need to put it in your window any more.
