Are there times when the transponder’s signal is not picked-up? Why does this happen?
Our remarkable electronic tolling system is over 99.9% accurate. But, like most technology, it is not perfect all of the time. In less than one per cent of the time, the signal can be missed. Here are the reasons:
* The transponder battery may be older than five years and need replacing.
* You have improperly mounted the transponder in the vehicle, sending its signal into the dashboard, passenger seat and so forth.
* Some cars have coated windshields that obstruct the signal. Some makes of cars will do this infrequently and some more often. Give us a call at 1-888-407-0407 and we will gladly assist you.
* Drivers who typically share their transponder between vehicles are more likely to not have it in their car one day and may not notice. In this case, you will receive a Video Toll Charge and will be responsible for those charges.
(When transponder users exit the highway, a properly working transponder will beep 4 times indicating the end of the trip.)
As for the coated windshield, I can't speak to the possibility of this on the 2012's, but my EZ-Pass
