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.
I'm the type who prioritizes driving efficiency, so the ETC must be optimally positioned at the center of the windshield near the roofline. Once installed there, it ensures strong signal reception, no delays at toll booths, and eliminates the hassle of manual payments. I chose this spot because it stays out of the driver’s line of sight, avoiding distractions, and once firmly attached, it won’t loosen even on bumpy roads. A word of caution—avoid installing it near dark tinted film or the frame edges, as that can disrupt the signal. After installation, passing through tolls is much smoother, and routine maintenance like card or battery replacement is easily accessible. Overall, selecting this precise location enhances driving convenience.
From a safe driving perspective, I insist on installing the ETC device in the upper middle section of the windshield. Positioning it slightly higher ensures it doesn't obstruct the forward view, maintaining clear driving visibility. Stable signal reception is crucial – my tests confirm faster toll gate response in that location, avoiding sudden braking risks. Incorrect placement near metal structures could cause signal failure and payment issues. After installation, I regularly check the device's stability to prevent detachment while driving. Choosing that spot overall makes usage safer and more reliable.
