How to use ETC during highway toll-free periods?

[DiVictoria]

During highway toll-free periods, the ETC passage methods are: 1. Enter through ETC lane and exit through ETC lane - no charge; 2. Enter through manual lane and exit through manual lane - no charge; 3. Enter through manual lane and exit through ETC lane - no entry information, exit barrier won't lift and vehicle cannot exit; 4. Enter through ETC lane and exit through manual lane - passable without charge. ETC is an Electronic Toll Collection system for automatic toll collection on highways or bridges. It uses dedicated short-range communication between the onboard unit installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations, combined with computer networking technology for backend settlement processing with banks, achieving the purpose of vehicles paying highway or bridge tolls without stopping at toll stations.
