The ETC is generally 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 lower middle part. The appropriate installation position should be no less than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 90 degrees. For vehicles with anti-explosion film or those that have been retrofitted with anti-explosion film, it may affect the signal transmission of the microwave communication link, and it should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, which means electronic toll collection system. To apply for ETC, the vehicle owner needs to provide the original and photocopy of their valid ID card and vehicle license. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle license should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Documents required for company vehicles: Introduction letter from the vehicle owner (with official seal); Copy of the organization code certificate or business license (with official seal); Original ID card of the agent; Original vehicle license; Vehicle that needs to apply for ETC. Here are the precautions for installing ETC: Do not block the view, it is best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, resulting in a smaller driver's field of vision. If this is not considered when installing ETC, it will increase the driver's blind spot. Install it behind the right side of the rearview mirror to avoid blocking the view. Do not affect charging: The ETC electronic tag consumes power, but generally does not need to be charged or have its battery replaced, as there is a solar panel on its back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and do not install it in a position that easily blocks the solar panel. Once installed, do not remove it at will: The button in the middle of the adhesive is an anti-removal guide rod, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal guide rod in. If it is removed at will, the anti-removal guide rod will pop out and trigger the switch, locking the electronic tag and making it unusable. You will need to go to the ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Precautions for using ETC: The ETC transaction sensing area is 8 meters. To prevent the ETC device failure of the vehicle in front, keep a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front; The recognition speed of the ETC lane is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, resulting in a failed deduction; When using a debit card to bind ETC, insufficient balance will also lead to a failed deduction.

As a veteran driver who commutes 50 kilometers daily, I have plenty to say about ETC installation positions. The most recommended spot is the black ceramic dot area behind the rearview mirror, that dark section at the top center of the windshield. This location doesn't obstruct visibility at all, and the solar panel charges normally. Remember to absolutely avoid areas with metalized film—my colleague installed it near metallic tint once, and it kept failing to read at toll booths until we reinstalled it. Here's a pro tip: clean the glass with alcohol before applying double-sided tape during installation, so it won't come loose even on bumpy roads—mine's stayed firmly in place for three years. A properly installed ETC makes the barrier arm lift instantly at toll gates, hassle-free.

With over a decade of long-distance freight experience, I know that poor ETC placement directly impacts efficiency. The optimal position is the upper right black grid area on the windshield, about an arm's length from the driver. This offers three advantages: easy button access, unobstructed solar charging, and no interference with the right rearview mirror. Don't cut corners by mounting it on the dashboard—I once saw a rookie place their ETC by the AC vent, and the adhesive melted in the sun, causing the device to shatter. When installing, insert the card fully until you hear a 'beep,' or you might get stuck at toll gates with 'card not inserted' errors. I was once trapped in an ETC lane for ten minutes with honking drivers behind me—it was nerve-wracking.

As a seasoned aesthetics enthusiast in the car club, ETC installation must balance practicality and visual appeal. My top recommendation is the black border area on the windshield directly behind the rearview mirror. This location makes the device virtually invisible from outside the vehicle – on my white SUV, it blends seamlessly with the window frame. Avoid the transparent central area of the windshield at all costs. A friend insisted on central placement for symmetry, only to suffer from glaring sunlight reflections and obstructed visibility. Pro tip: Visit a car wash beforehand to borrow their positioning stickers for trial placement before final installation. My ETC has been installed this way for two years, consistently earning compliments at meetups for looking like factory-installed equipment – far neater than those dangling units with messy cables around the dashboard.
