Can ETC be installed without sticking to the windshield?

ETC can be used without being stuck to the windshield. Installing the ETC on the upper part of the windshield is intended to minimize obstruction of the driver's view while ensuring better recognition by highway toll station equipment. If you prefer not to install it on the windshield, it should be placed in an open area where it can still be seen through the windshield. For small cars, the ETC 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 at a height of no less 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 built-in or aftermarket anti-explosion film, which may interfere with microwave signal transmission, the ETC should be installed in the microwave window area. Here are some precautions for installing ETC: Do not obstruct the driver's view; the best position is behind the rearview mirror: Many car models have windshields with a steep angle, which can reduce the driver's field of vision. Installing the ETC without considering this may increase blind spots. Placing it behind the rearview mirror on the right side can help avoid blocking the view. Avoid interfering with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a built-in solar panel for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The adhesive pad has an anti-tamper pin connected to a switch. Once installed, the windshield presses this pin in. If the tag is removed, the pin pops out, triggering the switch and locking the device, rendering it unusable until unlocked at an ETC service center. This feature prevents multiple vehicles from sharing one device. Things to note when using ETC: The ETC transaction sensing range is 8 meters. To avoid issues caused by a malfunctioning ETC device in the vehicle ahead, maintain a distance of at least 10 meters to prevent automatic payment for the preceding vehicle. The ETC lane recognizes vehicles at a speed of 20 km/h; exceeding this speed may result in failed transactions. If using a debit card linked to ETC, insufficient balance may also cause transaction failures.
