Can I apply window film after installing ETC?

[McMax]

You can apply window film after installing ETC. Since ETC devices are usually installed on the front windshield, and the film applied to the front windshield has good light transmittance, it won't affect the ETC device. However, dark-colored films may impact the solar panel of the ETC device. If you've installed ETC, you can first remove the device, apply the film, and then reactivate and reinstall the ETC at the bank. The ETC application process: Prepare the vehicle owner's ID card, credit card holder's ID card, credit card, and vehicle registration certificate. Visit the nearest bank branch to submit the application request and wait for processing. The function of ETC is to enable vehicles to pay highway or bridge tolls without stopping at toll stations.
