How to Deal with ETC Overcharging Issues?

[LeFinley]

Solutions for ETC overcharging issues: Visit the bank for consultation and resolution. First, print out the transaction details and travel records of your personal ETC card, then carefully verify each fee item. If incorrect charges are confirmed, you can request a refund from the bank. Precautions for ETC usage: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of over 10 meters to prevent automatic fee deduction for the vehicle in front, in case its ETC device is faulty or absent. The ETC lane recognizes vehicle speeds up to 20km/h. Speeding may result in failure to read the vehicle's device information and unsuccessful fee deduction. Unauthorized removal or movement of the OBU device, detachment, or loosening of the ETC electronic tag can render the tag invalid. It can be taken to the bank where the ETC card was issued or to a highway service center for inspection. If the detachment or loosening is not due to human intervention, reactivation may suffice. When using a debit card linked to ETC, insufficient balance can lead to fee deduction failure. Follow the guidance of on-site staff to use the manual MTC lane with cash or card payment. Excessively thick car windshields may cause poor signal reception. This is particularly important for vehicles that have had their windshields replaced after accidents or for those with modified front windshields.
