Where to Stick the ETC on the Windshield?

ETC should be affixed to the upper right corner of the windshield in front of the front passenger seat. ETC (Electronic Toll Collection) is an automatic tolling system for highways or bridges, utilizing dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at toll stations. It employs computer networking technology for backend settlement processing with banks, enabling vehicles to pass through highway or bridge toll stations without stopping to pay tolls. Precautions for ETC installation: 1. Do not obstruct the driver's view; 2. Avoid interfering with device charging; 3. Do not remove the device arbitrarily after installation.

I think the placement of the ETC tag is quite crucial. Based on my own experience, it's always best to place it on the upper side of the driver's side of the front windshield, near the rearview mirror. This spot doesn't obstruct the view while driving, ensures stable signal reception, and allows the toll station reader to detect it directly, avoiding errors when passing through toll booths. If it's placed too off-center or obstructed, it might not be sensitive enough, causing unnecessary delays. Also, avoid dark-tinted or metal-coated glass as it can interfere with signal reception. Regularly check if the tag is securely attached to prevent it from falling off or getting wet, which could lead to future repair hassles. When installing, make sure to clean the glass thoroughly before attaching the tag to ensure strong adhesion and prevent loosening. Safety comes first—choosing the right spot gives peace of mind while driving, especially during nighttime highway trips.

The optimal position for the ETC device is the central area at the upper part of the windshield, close to the roof edge. Based on my multiple tests, this location ensures the strongest sensor signal reception, enabling efficient recognition of toll station antennas and reducing misreads or delays. The principle is that the device's internal antenna performs best here with minimal signal interference from the roof proximity, whereas other areas may be affected by glass tint or vehicle metal. Avoid installing it in extreme corners to prevent obstructing the driver's view and causing accidents. Additionally, check the adhesive during significant temperature changes to prevent device displacement and functional issues. Improper positioning may also lead to charging or battery problems, resulting in time-consuming maintenance. In short, finding the right spot ensures smoother system operation.

When I installed the ETC device, I placed it right above the driver's seat on the windshield, slightly towards the top edge of the window. This position doesn't cause any visual obstruction while driving, and the signal reception is excellent – no delays when passing through ETC lanes. Remember to wipe the glass dry before firmly pressing it on to avoid having to reinstall it if it falls off. Getting the position right makes daily usage hassle-free.
