What does it mean when the ETC light turns green?

[JacksonMarie]

It is normal for the ETC sensor to flash green when the car is started, indicating that the sensor is detecting. Many highways have ETC gantries installed. The sudden beeping and flashing green light of the in-car ETC card is due to these gantries. Their function is to read the corresponding vehicle information when a vehicle equipped with an ETC electronic tag passes by, and then use computer networking technology to perform background settlement processing with the bank. Relevant information about ETC is as follows: 1. Introduction: ETC is an electronic toll collection system for highways or bridges that allows for automatic payment without stopping. 2. Working Principle: The working principle of ETC involves dedicated short-range communication between the on-board ETC electronic tag installed on the vehicle and the ETC microwave antenna on the toll station lane. It uses computer networking technology to perform background settlement processing with the bank, achieving the purpose of vehicles passing through highway or bridge toll stations without stopping to pay the toll.
