Solution for selling the car but not deregistering the ETC: Bring documents such as the vehicle license and ID card to the highway ETC service point to unbind the device. After returning the device, the counter will issue an unbinding form. After 45 days, bring this form and the corresponding bank card to the bank to complete the unbinding process. You can also bring the documents for the new car to rebind it to the new vehicle. For the new car, bring the relevant procedures provided by the bank to the highway ETC service point to install the OBU. ETC, or Electronic Toll Collection, is a system where vehicles automatically deduct the corresponding fees from a pre-bound IC card or bank account when passing through highway toll stations via onboard equipment.

The car was sold but the ETC wasn't canceled, this needs to be handled promptly. I understand many people forget when selling their car, but the ETC is linked to your account. If the new owner uses the highway, the fees will continue to be deducted from your card, and you'll be stuck with a pile of bills. Contact the ETC service center, bring the vehicle sales contract and ID to an offline location to cancel, or call customer service—it can be resolved in just a few minutes. Additionally, some ETC devices can be removed and re-registered for someone else to use, so it's a waste to discard them. In short, don't delay—handle it as soon as you notice to avoid unnecessary charges. Delaying a few days could cost you hundreds extra, wasting both money and time.

I also encountered the issue of not canceling the ETC when selling my car, and only realized the problem when I received the bill. I quickly went to the ETC service center, provided the proof of car sale, and they were able to deactivate the device. Remember to bring a copy of your ID and the old license plate information to prevent the new owner from deducting money from your account. Delaying this could lead to accumulated fees affecting your credit record, making it more troublesome to resolve. It's advisable to pay attention to this when selling your car and include the cancellation as part of the transaction process. Neglecting small details can lead to big troubles later on.

Don't panic if your ETC isn't canceled. The simplest solution is to immediately contact ETC customer service and provide vehicle sale documentation to apply for deactivation. Most regions support online APP operations or phone processing, saving you a trip. If left unresolved, the new owner may continue using it, resulting in ongoing charges for you and potential blacklisting. Just get it sorted promptly.
