What is the situation when the highway ETC does not deduct fees?

[PenelopeMarie]

There are two situations when the highway ETC does not deduct fees. One is that the barrier is damaged, and the vehicle passes through the ETC lane too fast, resulting in a failed fee deduction. The other is that the ETC fee deduction is on an account basis, meaning it will not be deducted immediately but will be deducted within a certain period. Precautions for using ETC: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front stopping, 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 sensing and paying for the vehicle in front. The recognition speed for ETC lanes is 20km/h. If the vehicle speed is too fast, the vehicle device information cannot be read, which will also result in a failed fee deduction. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was processed or the highway service office for testing. If the loosening or detachment is not man-made, it only needs to be reactivated. When using a debit card to bind ETC, insufficient balance will also result in a failed fee deduction. Follow the guidance of on-site staff to go to the manual MTC lane and use cash or card for passage. Poor sensing due to overly thick car windshields. Especially for vehicles that have had accidents and had their windshields replaced, or vehicles with modified front windshields, extra attention is needed.

When I drive on the highway using ETC, I occasionally encounter instances where the fee isn't deducted, usually due to system delays. Nowadays, the highway backend is often busy, and the deduction information may only appear in the app a few days later. Another reason could be that the small device in the car—the ETC tag—has run out of battery or become loose, leading to poor signal reception and failure to deduct the fee. Insufficient account balance is also a common cause, so it's necessary to check if there's money in the linked bank account. Additionally, equipment malfunctions in the toll lane or weak network signals can interrupt the deduction process. My advice is not to panic; wait a day or two and check the records in the mobile app. If this happens repeatedly, inspect the installation position of the ETC tag or contact customer service to make up the payment to avoid affecting your credit score. While ETC is convenient for highway travel, occasional minor glitches can occur—just handle them promptly.

As someone who loves tinkering with cars, I've found that ETC non-payment often stems from technical issues. The first suspect is ETC tag malfunction, such as battery depletion or physical damage causing signal failure. Second is lane sensor errors - rainy days or excessive dust can easily cause problems. Third is account system bugs, like server congestion delaying bill processing. First, manually check if the tag indicator light is working normally - a green light means it's good; then check bank app records for any anomalies. If everything seems fine, it might be backend network lag, which should automatically deduct later. Daily recommendation: regularly test equipment to prevent issues, simple maintenance saves trouble.

I just started learning to drive and once encountered an issue with the ETC not deducting the fee. I asked an experienced driver friend, who said it's mostly due to the device being installed crookedly causing poor signal or slow backend system processing. New drivers often overlook these details, but don't panic—just wait for the bill; the fee will eventually be deducted. If you're really worried, check the APP to confirm.
