What does ET mean at the entrance and exit of expressway toll station?

ETC is a non-stop electronic toll collection system, and ETC lanes are used for vehicles equipped with ETC on-board equipment.

ETC (Electronic Toll Collection) system is the most advanced road and bridge toll collection method in the world. The vehicle-mounted electronic tag installed on the windshield of the vehicle communicates with the microwave antenna on ETC lane of the toll station in short distance, and the computer networking technology is used to make background settlement with the bank, so that the vehicle can pay the road and bridge fees without stopping at the road and bridge toll station.
