Where is the ETC installed in the car?

ETC is installed on the front windshield of the vehicle, as long as it does not obstruct the driver's line of sight. Correct installation position for ETC: 1. The height should not be less than 1.2 meters or more than 2.5 meters; 2. The installation angle should be between 30 degrees and 90 degrees; 3. For small vehicles such as cars and minivans, the OBU device should be installed in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, the installation position is in the middle lower part. The ETC device's electronic tag communicates via microwave short-range communication with the microwave antenna on the ETC lane at toll stations, using computer networking technology to process background settlements with banks, achieving the purpose of vehicles passing through toll stations without stopping to pay toll fees.
As a seasoned driver with years of experience, I highly recommend installing the ETC device at the top center of the windshield's interior, right next to the rearview mirror. This elevated position ensures it doesn't obstruct your view while driving and guarantees smooth signal detection by toll station antennas, eliminating the need to slow down when passing through. I chose this spot for my own installation—just clean the glass and firmly attach it. Be sure to avoid areas with sun tint films or metal decorations, as these can weaken the signal and affect payment accuracy. Once properly positioned, daily use is hassle-free, especially during long trips with automatic toll booth passage, saving both time and effort. I occasionally check the battery and adhesive stability to prevent issues from prolonged sun exposure. Correct placement makes the entire ETC experience seamless and trouble-free.
