What to do if the ETC device falls off by itself?

ETC tags have an anti-removal feature. Once they become loose or fall off, you need to go to the original issuing point or the provincial expressway ETC service center to reactivate and reinstall them. If the ETC device falls off, you can use the manual lane for toll payment, so there's no need to worry about this. Be sure to keep the ETC card and transmitter device waterproof, avoid demagnetization, prevent violent damage, and prohibit disassembly by non-professionals.
I noticed my ETC tag suddenly fell off. First, check if the device is damaged or cracked. If the surface appears intact, it's likely just the adhesive that failed. In this case, you can reattach it to the windshield using automotive-grade adhesive; cleaning the glass before applying glue will make it more secure. However, if the device is damaged, promptly contact your ETC service provider, such as your bank or highway service department—they'll express mail a new tag to you. Meanwhile, remember to use manual lanes as a temporary alternative before hitting the highway. With over a decade of driving experience, I've often seen this happen due to summer heat aging the adhesive, so regularly wiping the glass during maintenance can prevent it. Additionally, testing whether the tag functions properly is crucial—don't let signal interference compromise driving safety.
