It is normal for the ETC sensor to flash green when driving, indicating that the sensor is detecting. ETC gantry has been built on many highways.

The reason why the etc card in the car suddenly beeps and flashes green is because of the gantry. The function is to enable vehicles equipped with ETC electronic tags to read the corresponding vehicle information content when passing by, and then use computer networking technology to perform background settlement processing with banks.

Each bank basically has a separate ETC credit card. The credit card account is used as a debit account for highway tolls, and cardholders can enjoy the convenience of traveling quickly.

Technical Features

The non-stop toll collection technology is particularly suitable for use in highways or bridges and tunnels with heavy traffic. The non-stop tolling system under traditional lane separation measures is usually called a single-lane non-stop tolling system, and the non-stop tolling system under free traffic flow without lane separation is usually called a free-flow non-stop tolling system.

The implementation of non-stop tolling can allow vehicles to pass at high speed (tens of kilometers or even more than 100 kilometers), so it can greatly improve the traffic capacity of the highway; the trend of electronic highway tolling can reduce the cost of toll management, and has It is beneficial to improve the operating efficiency of vehicles; at the same time, it can also greatly reduce the noise level and exhaust emissions at the toll gate.
