ETC Installation Location?
4 Answers
For small cars, the ETC device is generally installed on the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed on the lower middle part. The appropriate 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, 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, an electronic toll system. To apply for ETC, the vehicle owner needs to provide valid identification and the original and photocopy of the vehicle registration certificate. If the application is made by someone other than the owner, the agent's valid identification is also required. The photocopy of the vehicle registration certificate 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. Documents required for official vehicles: An introduction letter from the vehicle owner (with official seal); a photocopy of the organization code certificate or business license (with official seal); the original ID of the agent; the original vehicle registration certificate; and the vehicle for which ETC is to be applied. Here are some precautions for ETC installation: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large inclination 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. Installing it behind the rearview mirror on the right side can 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 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 the device is removed casually, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Precautions 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 deduction for the preceding vehicle. The ETC lane recognizes vehicles at a speed of 20 km/h; driving too fast may result in failure to read the vehicle's device information and unsuccessful toll deduction. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failure.
When I first installed the ETC, I chose a spot on the inside of the front windshield, usually slightly above the center, just not directly in the driver's line of sight. I once tried placing it too far to the side, and the toll booth often failed to recognize it, which was a hassle. Now, I've fixed it in that position mainly so the external antenna can scan it directly without needing to get out of the car. Before installation, it's best to clean the glass thoroughly and use the provided double-sided tape to secure it firmly, ensuring it doesn't wobble. Also, avoid placing it over areas covered by window tint film, as the signal can be disrupted. I've driven several cars, both SUVs and sedans, and the positioning principle is pretty much the same. Keeping it securely in place ensures smooth passage on highways, making things much more convenient.
I've seen many people install ETC devices at the car factory, and the most standard location is the central area of the front windshield, a few centimeters from the top. This position ensures smooth signal transmission without obstructing the driver's view. When installing, be careful not to place it too high, as it may block visibility, and avoid sticking it near the rearview mirror. I've encountered some drivers who cleverly placed it on the dashboard, only to face poor signal reception at toll stations, leading to incorrect charges. It's best to choose the right spot, clean the glass thoroughly, and secure the device firmly. Different car models, such as sedans, may have varying windshield angles, but the basic principle remains the same. Always test the installation afterward to avoid common issues.
The ETC device is usually installed on the inner center of the car's front windshield. This location is crucial because signal reception may be poor elsewhere. I installed it myself by simply cleaning the glass and securing it with adhesive tape, ensuring it doesn't obstruct the driving view. During daily use, be careful not to let children touch it randomly, as any looseness may affect its sensing. Regularly check to ensure it's firmly in place for smooth recognition at toll stations.
