What does 'ETC without tag' mean?
1 Answers
ETC without tag means the ETC electronic tag is invalid. Since ETC is designed for dedicated vehicle use, it has a protective interlock installed during setup - specifically the button at the back. If this button is triggered twice consecutively, it will cause the ETC electronic tag to become invalid. ETC stands for Electronic Toll Collection system, where ETC-exclusive lanes are designated for vehicles equipped with ETC onboard units, utilizing electronic payment methods. The ETC system works through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna at the toll station's ETC lane. This system employs computer networking technology to process backend settlements with banks, achieving the purpose of allowing vehicles to pass through toll stations without stopping while paying toll fees.
