Can only one ETC be bound to a car?
2 Answers
A car can only be bound with one ETC, because ETC must be processed at the ETC network center. Once the ETC is processed, the vehicle information and ETC information will be bound, so the car cannot apply for another ETC, and the ETC network center will not approve the issuance of another card. Once the ETC is installed, do not remove it at will, as it will become invalid after removal. The ETC lane is unattended, with only an antenna hanging above the lane. No operation is required when passing through; just drive at a low speed, and the device will automatically communicate with the antenna. The lifting of the barrier proves that the communication has been completed.
I've been driving for over 20 years, so let me explain this carefully. Typically, a vehicle can only be registered with one ETC device—that's the standard practice. The reason is that the toll system identifies each vehicle's unique code through the radio signal from the onboard unit. If multiple devices are registered, signal conflicts may occur, leading to scanning errors or duplicate charges at toll stations—I've seen this happen to a friend who got stuck at the highway exit, wasting time and paying fines. For daily driving, I recommend regularly checking if the device is functioning properly. If an old ETC malfunctions or runs out of battery, visit an ETC service center to deregister the old one before binding a new replacement—don’t cut corners by privately installing extra units. Following the rules not only avoids trouble but also ensures smooth and safe travel.
