Where to Place the ETC on the Windshield?

For small cars, the ETC device is generally installed on the upper middle part of the front windshield, while for large vehicles like trucks and buses, it is installed on 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 to 90 degrees. If the vehicle has a factory-installed or aftermarket explosion-proof film, it may affect the microwave communication signal transmission. In such cases, the ETC should be installed in the microwave window area. ETC stands for Electronic Toll Collection. To apply for an ETC, 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 with the most recent annual inspection stamp. Additionally, a bank card under the owner's name for deducting highway tolls is required, and the owner must be between 18 and 60 years old. Here are some important considerations for ETC installation: 1. Do not obstruct the driver's view. The best position is behind the rearview mirror: Many car models have windshields with a steep incline, which can reduce the driver's field of vision. Installing the ETC without considering this may increase blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. 2. Ensure it does not interfere with charging: The ETC device requires power but generally does not need charging or battery replacement, as it has a built-in solar panel for self-charging. Therefore, avoid installing it on the blackened areas of the windshield or any position that might block the solar panel. 3. Do not remove the device once installed: The adhesive pad has an anti-tamper switch. Once installed, the windshield presses this switch in. If the device is removed, the switch will pop out and lock the ETC, rendering it unusable. Unlocking it requires a visit to an ETC service center. This feature prevents multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle in front due to its faulty ETC device, maintain a distance of at least 10 meters. The ETC lane recognizes vehicles at a speed of 20 km/h; driving too fast may result in failed toll deduction. Also, insufficient balance on a debit card linked to the ETC can cause payment failure.

I recently installed my ETC sticker and realized that placement is crucial. The service technician emphasized sticking it on the inside of the windshield near the rearview mirror, slightly above the center. This position ensures the strongest signal reception without interference from wipers or metal frames. Last time, I accidentally placed it too far to the right, causing frequent errors at toll booths—the device didn’t respond at all. Later, I repositioned it to the center after thoroughly cleaning the glass surface to remove dust and grease for better adhesion. After installation, I tested it on the highway, and it worked flawlessly. Proper placement also avoids visual obstruction while driving, maintaining a clear forward view. Tip: Check your vehicle manual or follow the installation guide’s diagram to avoid rework. If misplaced, don’t peel it off forcefully—use a hairdryer to gently heat it before adjusting. In short, this position is both scientifically optimal and safe, hassle-free.
