What is the best location to install an ETC device?

For small cars, the ETC device is generally installed in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the lower middle part. The suitable installation position should be at a height of no less than 1.2 meters and no more 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, which may affect the signal transmission of the microwave communication link, the device should be installed in the microwave skylight zone. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for it, you need to provide the original and photocopy of the vehicle owner's valid ID and driving license. If the application is not made by the owner, the agent's valid ID is also required. The photocopy of the driving license should include the page with the most recent annual inspection seal. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Here are some precautions for installing ETC: Do not block the view; it is best to install it behind the rearview mirror: Many car models have windshields with a large backward tilt angle, which reduces the driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spots. Installing it behind the rearview mirror on the right side can 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, during installation, avoid the black 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-removal lever connected to a switch. After installation, the windshield will press the anti-removal lever in. If 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 area 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 payment for the vehicle ahead. The ETC lane recognition speed is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle's device information and cause payment failure. When using a debit card bound to ETC, insufficient balance will also lead to payment failure.
Choosing the right location for installing your ETC device is crucial. With years of driving experience and trying several spots, I found the best place is near the center or the driver’s side of the rearview mirror on the front windshield. This area offers an unobstructed view and stable signal reception, preventing misreads at toll booths. Remember not to install it on dark tinted film—the metal in the film can block signals, leading to frequent failures. I cleaned the glass with alcohol before applying double-sided tape, and the result was excellent. Installing it on the dashboard or behind the sun visor can obstruct your view, affect aesthetics, and increase driving risks. Regularly check the adhesive to prevent the device from loosening or falling off. Safety first—just find a spot that doesn’t get in the way.
