Can ETC only be used for one vehicle?

[StGianna]

ETC can be used for multiple vehicles with one card. According to the "Rules for the Use of Non-Stop Express Passage Systems," when applying for an ETC card, you need to fill out the "ETC Service Deduction Authorization Form." When specifying the vehicles for payment binding, multiple vehicles can be listed. This means there is no limit to the number of vehicles that can be bound to a single ETC card for payment purposes. ETC is a non-stop electronic toll collection system, also known as an automatic road payment system. It is a specialized method for toll roads, commonly seen on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion. ETC Deduction Principle: Highways have one or more ETC lanes. Communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane enables automatic toll deduction through computer network technology and bank settlements. This allows vehicles to pass toll stations without stopping, operating on a "pass first, deduct later" principle. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Reduces noise and exhaust emissions by avoiding stops at toll booths; Cost-saving: Minimizes vehicle wear and fuel consumption by reducing frequent starts and stops; Efficiency improvement: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC faster and more advanced. Compared to license plate payment, ETC technology is more mature and advantageous. More Policy Support: The State Council's "13th Five-Year Plan for the Development of a Modern Integrated Transportation System" explicitly states the goal of "achieving interoperability of transport cards in key city clusters by 2020 and significantly increasing the adoption rate of ETC in vehicles." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020." Future Possibilities: Beyond improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will promote ETC adoption for trucks and explore deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide comprehensive travel services for vehicle owners, expanding ETC applications to more scenarios.
