If ETC fails to deduct fees properly, you can go to the bank where you applied for the ETC service. The specific process is as follows: Bring the original and photocopies of the vehicle owner's valid ID card and vehicle license. The photocopy of the vehicle license should include the page with the most recent annual inspection stamp. Fill out an application form for a refund. The bank will verify the account and confirm any incorrect deductions. After verification by the bank, the overcharged fees can be refunded. Precautions for using ETC: The ETC transaction sensing range is 8 meters. To prevent the vehicle in front from having a faulty ETC device or no ETC device at all, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic payment for that vehicle. The speed limit for ETC lane recognition is 20 km/h. Driving too fast may prevent the system from reading the vehicle's device information, leading to failed deductions. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, can cause the electronic tag to malfunction. You can take it to the bank where you applied for the ETC card or the highway service office for inspection. If the detachment or loosening is not due to human error, reactivation may be sufficient. When using a debit card linked to ETC, insufficient balance can also cause deduction failures. Follow the guidance of on-site staff and use the manual MTC lane, paying with cash or card. Thick car windshields may cause poor signal reception. This is especially important for vehicles that have had their windshields replaced after an accident or for those with modified front windshields.
