Where to Place ETC in the Car?
2 Answers
The installation position of ETC for small cars is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the middle to lower 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 built-in or later-added explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC is the abbreviation of Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the owner needs to provide the original and photocopy of their 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. Here 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 rearward tilt 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 spot. Installing it behind the rearview mirror on the right side can avoid obstructing 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 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 the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In this case, 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 toll payment for the preceding 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 and cause toll deduction failure. When using a debit card linked to ETC, insufficient balance may also lead to toll deduction failure.
I've been driving for over a decade, and that ETC gadget is usually stuck on the front windshield, right next to the rearview mirror. Why there? Because it needs to communicate signals with the toll station equipment, and the glass at the top has good light transmission, allowing signals to travel far without blocking the view. When installing it, make sure to clean the glass thoroughly and use strong double-sided tape to secure it firmly, avoiding any tilting or sticking it near metal edges, which could weaken the signal. If it's not placed correctly, the toll station might not read the card, causing long queues and delays. I remember a friend once placed their ETC on the dashboard, and the signal was so weak it kept failing to work. Proper placement also reduces wear from shaking and extends battery life. It's a good idea to ask a friend who works in auto repair to help position it, ensuring the device is installed flat and being careful not to bump it while driving. Regularly check if the adhesive is loose and that the battery is in good condition.
