Where is the best location to install an ETC tag?

[DelJoseph]

The ETC installation position is generally in the upper middle part of the front windshield for most vehicles, 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 to 90 degrees. For vehicles with anti-explosion film or those that have it installed later, it may affect the signal transmission of the microwave communication link, so it should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply, the vehicle owner needs to provide their valid ID card and the original and photocopy of the vehicle registration certificate. If the application is done 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 needed, and the vehicle must be registered under an individual's name 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 registration certificate; Vehicle to be equipped with ETC. Here are some precautions for ETC installation: Do not block the view; it is best to install it behind the rearview mirror: Many car models have a large rearward tilt angle of the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Install it behind the rearview mirror on the right side to avoid blocking 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, avoid installing it on the blackened areas of the windshield or positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After installation, the windshield will press the anti-removal lever in. If removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and making 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. Notes for using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic toll payment for it. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle device information and cause toll deduction failure. When using a debit card linked to ETC, insufficient balance may also lead to toll deduction failure.
