Where is the ETC generally installed on the windshield?

[Lukas]

The ETC installation position is generally in the upper middle part of the front windshield horizontally, while for large vehicles such as trucks and buses, the installation position is in the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic Toll Collection. To apply for it, the vehicle owner needs to provide their valid ID card and the original and photocopy of the vehicle registration certificate. If the application is handled by a proxy, the proxy's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page stamped with the most recent annual inspection seal. A bank card for deducting highway tolls is also required, 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); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle registration certificate; the vehicle for which ETC is to be installed. Below are precautions for ETC installation: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, which can reduce the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device.

I've always thought the placement of ETC devices is quite particular. Most cars have them installed on the windshield behind the rearview mirror, either slightly to the right or left of center. This position is ideal because it doesn't obstruct the driver's view while ensuring the sensing device aligns properly with the toll station's signal receiver. When installing, feel the inside of the glass to find a flat and smooth area, preferably away from printed black dot matrix patterns, as these can cause poor signal reception. Clean the glass surface thoroughly before applying the adhesive, and press firmly for 30 seconds to ensure a secure bond. Once, I casually stuck it near the edge, and it responded sluggishly at the highway toll gate, which was quite frustrating.

Install it near the top of the windshield, specifically in the area around the rearview mirror. On my own car, I placed it behind the rearview mirror on the driver's side, which doesn't obstruct the view at all. The most crucial point is to ensure it's firmly attached, especially during summer heat to prevent the device from falling off. One thing often overlooked during installation: try to avoid the black dotted area directly behind the rearview mirror, as it may interfere with signal transmission. Some car owners take the easy route and stick it directly on the black dots, resulting in frequent sensor failures and having to manually roll down the window to swipe the card, which ends up being more troublesome. When positioned correctly, passing through highway toll gates becomes exceptionally smooth.

The best spot is directly on the front windshield near the top, next to the rearview mirror base. This way, it won't block your view, and the device's solar panel can still get sunlight. Remember three key points: 1) Stick it on the dry area, avoiding the black grid; 2) Press firmly with your fingers for half a minute to ensure it's secure; 3) Avoid areas not swept by the wipers. A friend tried sticking it on the side window and got fined 200 yuan for obstructing the license plate in a toll booth photo. Honestly, choosing the right spot isn't just about convenience—it's mainly to avoid unnecessary trouble.

The positioning is actually quite simple - just stick it on the upper part of the windshield. Most experienced drivers choose the area behind the rearview mirror because it provides the most sensitive recognition at toll stations. What really requires attention are the installation details: the glass must be thoroughly cleaned without any dust or oil film, and after applying the adhesive, press firmly for at least half a minute. I learned this the hard way - once installed it without properly cleaning the glass, and the ETC device suddenly fell off while driving on the highway, dangling and swinging, scaring the driver behind who kept honking. It's recommended to avoid the black grid at the edges of the windshield during installation, as it significantly affects signal strength.

The area behind the rearview mirror is the ideal position, either slightly to the left or right. There are two key points: it must be securely attached and have unobstructed signal reception. When installing, try to stick it on the smooth area of the glass, avoiding those black grid dots. I've seen people take shortcuts by sticking it directly on the grid area, only to have the tag fail every time they pass through a toll booth. If there's absolutely no space behind the rearview mirror, you can slightly lower it and stick it on the blank area in the upper middle part of the windshield. But never stick it at the very bottom outside the wiper range, as it's prone to dust accumulation and signal blockage. It's best to get it right the first time, otherwise peeling it off and reinstalling is a hassle, and the adhesive won't stick well anymore.
