The ETC lane recognition speed is 20km/h. If the speed is too fast, the vehicle equipment information cannot be read, which will also cause the deduction to fail. Unauthorized dismantling and moving of OBU equipment, ETC electronic tags falling off or loosening, etc. wait. , will cause the electronic tag to become invalid, and it can be sent to the bank or highway office where the ETC card is issued for testing. If it falls off without artificial loosening, it just needs to be reactivated. When using a debit card to bind ETC, insufficient balance will also cause the deduction to fail.
