Why is ETC not deducting fees?

[GrahamLynn]

The reasons why ETC does not deduct fees are: 1. The service is not activated or the minimum amount for SMS notification has not been reached; 2. The settlement time between the highway company and the bank has not arrived. Precautions for using ETC are: 1. Maintain a distance of more than 10 meters from the vehicle in front to prevent automatic sensing from paying for the vehicle in front; 2. When using a debit card to bind ETC, insufficient balance may also cause the deduction to fail; 3. The recognized speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, which may result in failed deductions. ETC is an automatic toll collection system for highways or bridges. It uses dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, combined with computer networking technology to perform background settlement processing with the bank. This allows vehicles to pass through highway or bridge toll stations without stopping to pay the fees.
