Is ETC limited to one card per vehicle?

ETC is one card per vehicle, and one card can be bound to multiple vehicles. According to the "Rules for the Use of Non-Stop Rapid 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. In other words, there is no limit to the number of vehicles that can be bound to a single ETC card for payment purposes. ETC is an electronic toll collection system, also known as an automatic road toll system. It is a road toll method specifically designed for toll roads, commonly found on highways, bridges or tunnels with toll policies, and certain sections of urban centers to alleviate traffic congestion. ETC Deduction Principles: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, the system uses computer networking technology to perform backend settlement with banks. This allows vehicles to pay tolls without stopping at toll stations, all based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, thereby reducing wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can increase vehicle passage efficiency by 2-3 times, making traditional ETC more updated, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, intercity transportation smart cards will be basically realized in key city clusters, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC adoption rate for passenger vehicles, future efforts will include promoting ETC use for trucks and exploring deeper integration of the ETC system with smart transportation directions such as vehicle-to-vehicle communication and vehicle-road coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.

Hey, after using ETC highway tolling for so long, I think the most common scenario is having one card bound to one vehicle. The reason is that to prevent tolling errors, the system generally requires a dedicated card to match the corresponding onboard unit—otherwise, misidentification would be quite awkward. I’ve also heard some friends try using one card on another vehicle, only for the reader to malfunction or the toll center to deactivate the card outright, which is a hassle. Although one card can’t be universally used, if you have multiple cars at home, you can apply for different cards under the same account—banks or toll stations can handle this easily. The only thing to note is updating the binding info promptly when switching vehicles to avoid travel disruptions. Additionally, the one-card-per-vehicle design enhances security, reducing fraud risks. For those who frequently take long trips, getting used to this method saves time and effort. Remember to check your card’s status regularly to ensure smooth travels.
