Where to Install ETC on Trucks?

[JaydenLee]

For large vehicles such as trucks and buses, the recommended installation position is in the middle-lower part. The suitable installation height should be no less than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. If the vehicle has anti-explosion film or if it is applied later, it may affect the signal transmission of the microwave communication link. In such cases, ETC should be installed in the microwave skylight zone. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide original and photocopied versions of their valid ID card and vehicle registration certificate. If someone other than the owner is handling the application, they must also bring their own valid ID card. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection seal. Additionally, a bank card for deducting highway toll fees is required, and the vehicle must be registered under an individual aged between 18 and 60. Here are some important notes for ETC installation: Do not obstruct the driver's view. The best position is behind the rearview mirror: Many vehicle models have steeply angled windshields, which can reduce the driver's field of vision. If ETC is installed without considering this, it may increase blind spots. Installing it behind the rearview mirror on the right side can help avoid blocking the view. Avoid affecting charging: ETC electronic tags consume power but generally do not require charging or battery replacement, as they have a built-in solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that might block the solar panel. Do not remove the device once installed: The adhesive backing contains an anti-tamper lever connected to a switch. Once the ETC tag is installed, the windshield presses the lever in. If removed, the lever will pop out and trigger the switch, locking the device and rendering it unusable. In such cases, the user must visit an ETC service point to unlock it. This feature 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 avoid incorrect charges due to a malfunctioning ETC device in the vehicle ahead, maintain a distance of at least 10 meters from the preceding vehicle. The ETC lane recognizes vehicles at speeds up to 20 km/h; driving too fast may result in failed transactions. If using a debit card linked to ETC, insufficient balance will also cause transaction failures.

My experience driving trucks has taught me that the ETC device is usually installed on the upper inner side of the windshield near the rearview mirror. This ensures optimal alignment with the toll station antennas. Once, I installed it slightly off for convenience, and it couldn’t receive signals on the highway, causing a lot of trouble. So, positioning is key: place it slightly above the center of the windshield—clear of your view yet strong in signal. Before installation, clean the glass and stick it on, avoiding spots with black dots or defroster lines to prevent signal interference. When installed correctly, it speeds up toll passage, saving time and reducing queues. Over the years, my long-distance trips have been smooth thanks to it. New drivers should learn this trick—don’t just place it anywhere for looks; a wrong spot means wasted effort.

I usually tinker with car maintenance, and the ideal location to install the ETC device for trucks is on the inner side of the front windshield, near the rearview mirror. The reason is simple: that area provides the best signal transmission, as it won't be blocked by the vehicle's metal body or other obstructions, allowing the toll device to be recognized from a distance. When installing, avoid placing it too close to the edge or too low, as poor adhesion can lead to signal interruptions. I secure it with tape and check the power cable to ensure normal charging. Regularly inspect the device to ensure it's firmly attached and wipe off dust to prevent functional issues that could disrupt daily operations. Proper placement helps reduce incorrect toll deductions, ensuring drivers pass through smoothly and safely.

I just bought a truck recently, and installing the ETC was really simple. Just stick it on the small square area at the top of the windshield, next to the rearview mirror. I followed the manual, wiped the glass clean with a cloth, and stuck it on firmly—it doesn’t move at all. If the position is off, the toll gate might recognize it slowly or even get stuck. After installation, every time I pass through the toll station, it zooms right through—no need to stop and fumble for cash. So convenient! I’ve tried it a few times, and it works smoothly. Newbies don’t need to worry about being clumsy; just pick the right spot, and you’re all set.

Safety comes first when driving. The truck ETC device should be placed on the upper inner side of the windshield with a clear and unobstructed view to avoid distraction. Installing it too low or at the edges may block the driver's vision and slow down emergency response. I emphasize securing it firmly to prevent the device from falling and getting damaged or causing injury. Choosing the right position reduces signal issues and prevents disputes caused by toll collection errors. During installation, select a flat area to ensure stable adhesion, making it both safe and hassle-free.
