Can ETC be used without sticking it on the windshield?

ETC can be used without sticking it on the windshield. Installing ETC on the upper part of the windshield is to minimize obstruction of the driver's view and to ensure better recognition by the equipment at highway toll stations. If you don't want to install it on the windshield, try to place it in an open area where it can be seen through the windshield. For small cars, the ETC installation position is generally in the upper middle part of the front windshield, while for large vehicles like trucks and buses, it is installed 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 microwave communication signals, the ETC should be installed in the microwave window area. Here are some precautions for installing ETC: Do not obstruct the view. It's best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt, which reduces the driver's field of vision. If ETC is installed without considering this, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield will press the anti-tamper lever in. If the tag is removed casually, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid issues caused by the ETC device of the vehicle in front malfunctioning, maintain a distance of at least 10 meters from the vehicle ahead to prevent automatic payment for the wrong vehicle. The ETC lane recognition speed is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle's device information, leading to payment failure. If a debit card is linked to ETC, insufficient balance may also cause payment failure.
