Where is the ETC device installed?
2 Answers
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, the installation position is in 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 and 90 degrees. For vehicles with anti-explosion film or those that have had anti-explosion film applied later, it may affect the signal transmission of the microwave communication link, and the device should be installed in the microwave skylight zone. ETC stands for Electronic-Toll-Collection, which means electronic toll collection system. To apply for ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent must also bring their valid ID card. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required, and the vehicle must be registered under the name of an individual aged between 18 and 60. Below are some precautions for installing ETC: 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 can reduce the driver's field of vision. If this is not considered during ETC installation, it can 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 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. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, 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 mechanism 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 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 front vehicle. The ETC lane recognition speed is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle device information, leading to payment failure. When using a debit card linked to ETC, insufficient balance may also cause payment failure.
Let me tell you, the placement of the ETC device is crucial. After driving for several years, I've made it a habit to install it on the upper part of the windshield, near the rearview mirror area. That spot offers a clear view, doesn't obstruct driving visibility, and ensures stable signal reception, allowing the overhead sensors at toll stations to scan it directly. Installation is a breeze: first, wipe the glass clean with a dry cloth, then peel off the double-sided tape on the device and press firmly for a few seconds to secure it. Placing it too low isn't ideal—summer heat can cause overheating and shutdowns. Too high, and it blocks your view, which is unsafe. I once installed it crookedly, and it failed to scan at the toll station, leaving me embarrassingly stuck behind. It's also important to regularly check the adhesive's strength and reinforce it if it loosens to prevent it from falling off while driving. In short, choosing the right spot makes for a smooth and hassle-free experience—zooming through ETC lanes in a flash.
