ETC is fixed on the windshield in a position that does not obstruct the driver's view. It is usually placed near the central rearview mirror inside the car, or it can be attached to the dashboard close to the windshield. ETC utilizes computer networking technology to conduct background settlement processing with banks, enabling vehicles to pass through highway or bridge toll stations without stopping to pay fees. The use of the ETC electronic toll collection system reduces vehicle wear and fuel consumption, decreases air pollution, achieves energy savings and emission reductions, and benefits environmental protection. Additionally, it eliminates the need for cash payments for tolls, making it convenient for vehicle and financial management.

As an experienced long-distance driver, the placement of the ETC device on the car's windshield is crucial. It's generally best to position it in the top center area near the rearview mirror or slightly above the driver's side. This location ensures the ETC antenna can clearly receive signals from toll stations, avoiding interference from metal frames or sunshades that could affect communication efficiency. After testing various positions myself, I found the center spot to be the most reliable—it doesn't obstruct driving visibility, and when installed using the manufacturer-provided strong adhesive tape (after cleaning the surface), it stays firmly in place. Positioning it too high may cause signal issues, while too low could block visibility or interfere with wipers, so balance is key. Additionally, regularly check the adhesive to prevent detachment, especially in areas with large temperature swings where the glue may loosen. Ensuring correct placement saves hassle at toll stations. In summary, following the vehicle manual's recommended location is the most worry-free approach.

As a commuter, I pass through the ETC toll booth every day, and the most convenient fixed position is the upper left corner of the windshield. I prefer this spot because it doesn’t obstruct my view of the rearview mirror or the road ahead, making driving feel safe and relaxed. The installation steps are simple: first, clean that area thoroughly, then use the adhesive that comes with the device to stick it on, ensuring the device’s antenna is correctly oriented to avoid signal loss. Some people find the middle position works well too, but based on personal experience, the upper left corner is more effective—the toll booth recognizes it instantly, saving time and money. Avoid placing it too low where it might be blocked by clutter or too high in the tinted area where the signal weakens. I’ve used this setup for over a year without issues, though occasionally in cold weather the adhesive loosens slightly, and I just reinforce it. Choosing the right position makes driving much more enjoyable.

I prioritize driving safety, so the ETC device must be fixed at the top center or slightly to the left of the windshield, absolutely without obstructing the view. During installation, ensure it doesn't block the driver's view of the road ahead or the rearview mirror, otherwise, it increases the risk of accidents. After fixing it in that position myself, I tested it multiple times, and the signal remained stable without affecting visibility. An incorrect position might lead to failure at toll stations, causing inconvenience or sudden braking hazards. Keeping the device clean is also crucial.
