If you don't have enough money when exiting the highway with ETC, you can follow the guidance of on-site staff to go to the manual MTC lane and use cash or card payment to exit the highway. ETC Usage Precautions: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front stopping, to prevent the ETC device failure of the front vehicle or the absence of an ETC device, maintain a distance of more than 10 meters from the front vehicle to avoid automatic sensing and paying for the front vehicle. The ETC lane recognition speed is 20km/h. If the speed is too fast, the vehicle device information cannot be read, which will also lead to payment failure. Unauthorized disassembly or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for testing. Non-human-induced loosening or detachment only requires reactivation. When using a debit card bound to ETC, insufficient balance will also lead to payment failure. You can follow the guidance of on-site staff to go to the manual MTC lane and use cash or card payment to pass. Excessive thickness of the car windshield can cause poor sensing. Especially for vehicles that have had accidents and had their windshields replaced, or for those who have modified their front windshields, extra attention is needed.
