Is the FasTrak flex supposed to beep?

It’s okay if your FasTrak® transponder occasionally doesn’t beep when you pass through a tolling location. Usually when a transponder is silent, it is still working and if it does fail to read, the appropriate toll is deducted from your account based on a reading of the vehicle’s license plate number.
