What does the ETC toll photo on the highway mean?

[GemmaLee]

Highway ETC toll photo refers to the use of gantries to divide the highway into several sections. Gantries are devices installed on highways to calculate toll amounts, and they are placed at certain intervals. Each time a vehicle passes under a gantry, the cameras mounted on it will take photos and calculate the toll based on the vehicle type, and the corresponding toll fee will be deducted from the vehicle's ETC. ETC stands for Electronic Toll Collection, a system that is being actively developed and promoted internationally for electronic tolling, mainly used for the management of bridges, tunnels, highways, and parking lots. When a vehicle passes through a toll station, there is no need to stop; the system automatically identifies the vehicle via onboard equipment and deducts the corresponding fee from the pre-linked bank account or IC card. By using this system, drivers only need to install a transponder card on their windshield and pre-load a certain amount of money. When passing through a toll station, there is no need for manual payment or stopping, as the toll is automatically deducted from the card.
