Why does the ETC in the car beep?
1 Answers
ETC uses radio frequency for identification. It might beep due to interference from similar signals emitted by places like bus stations. If the ETC device keeps beeping continuously, it indicates an abnormality in the device, and it's best to have an ETC technician inspect it. Below are detailed explanations: 1. ETC: The ETC system communicates wirelessly between the onboard unit installed in the vehicle and the antenna on the toll station lane, exchanging information. It mainly consists of an automatic vehicle identification system, a central management system, and other auxiliary facilities. The automatic vehicle identification system includes the onboard unit (also known as a transponder or electronic tag), roadside unit (RSU), loop sensors, etc. 2. Usage Notes: To ensure more accurate path identification information, users should promptly return the toll card to the electronic tag after swiping it in the manual toll lane.
