Only one ETC can be applied for a vehicle. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Highways" issued by the Ministry of Transport, the application of ETC is related to the vehicle's driving license. If you own multiple vehicles, you can use different driving licenses to apply for ETC. Documents required for ETC application: The original valid ID card of the vehicle owner, the original and copy of the vehicle's driving license (the page with the latest annual inspection stamp must be provided). If applying on behalf of others, the original valid ID card of the agent is also required. If applying for ETC through major bank branches, a corresponding bank debit card or card must be prepared. Some banks only support ETC binding with credit cards, while others may require freezing a certain amount as a deposit when binding ETC with a debit card. ETC deduction principle: There will be one or more ETC lanes on highways. Through the dedicated short-range microwave communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane of the toll station, and using computer networking technology for background settlement with the bank, the purpose of paying tolls without stopping at the toll station is achieved. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Save time: Eliminates the hassle of queuing and waiting; Green and environmentally friendly: Green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduce wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improve efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times or more, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More support: The State Council clearly stated in the "13th Five-Year Plan for the Development of Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically realized, and the proportion of vehicles equipped with ETC will be significantly increased." It also set a clear target in the main indicators of the "13th Five-Year" comprehensive transportation development: "By 2020, the ETC usage rate of road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate of passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with the development directions of smart transportation such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front stopping, to prevent the ETC device of the front vehicle from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the front vehicle to avoid automatic sensing and paying for the front vehicle. The recognition speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, which will also lead to deduction failure. Unauthorized disassembly or movement of the OBU device, ETC electronic tag falling off or loosening, etc., will cause the electronic tag to fail. It can be sent to the bank where the ETC card was applied for or the highway service office for testing. If the loosening or falling off is not man-made, it only needs to be reactivated. When using a debit card to bind ETC, insufficient balance will also cause deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Excessive thickness of the car windshield may cause poor sensing. Especially for vehicles that have had accidents and replaced the windshield, or friends who have modified the front windshield need to pay attention.

I remember when I first bought my car, I wondered about this—could one car have multiple ETCs to avoid the hassle of swapping cards? After several trips to the bank, I finally understood: it's simply not allowed by ! In the vehicle management system, each car's license plate number is as unique as an ID number. If you secretly try to apply for a second ETC with a different bank card, the system will immediately detect the duplicate binding and reject the application on the spot. I once saw a neighbor who didn’t believe it and tried twice, only to get a warning call from the ETC center threatening to freeze his account if he kept it up. Nowadays, canceling is easy—just apply on the mobile app, and within a few days, the old one can be unbound for a new one. After all, the highway toll system relies on license plate recognition for automatic deductions. If the same car has two ETC devices, the signals will clash at the toll gate, causing issues ranging from the barrier not lifting to duplicate charges of hundreds of dollars.

I've been driving long-haul trucks for over a decade and replaced my ETC device three times. Let me make it clear: each vehicle can only activate one ETC device. Last year, my cousin tried to game the system by using the same vehicle registration to apply at two different banks. The first bank approved it, but the second bank's system automatically blocked the application as soon as he submitted the documents. The reason is simple: highway gantries are equipped with high-definition cameras and microwave sensors - your license plate must perfectly match the ETC device chip for proper toll deduction. If you forcibly install two devices, when both signals transmit simultaneously at the toll gate, the attendant's computer will flash a red alert and treat it as toll evasion. Once when my device malfunctioned, I borrowed a temporary ETC from our fleet dispatcher, but it caused recognition confusion at the gate and got me stuck for twenty minutes. You're better off focusing on maintaining your existing device - timely replacement to prevent failures is the real solution.

From a technical perspective, the ETC system functions like a sophisticated vehicle locking mechanism. Each OBU device mounted on the windshield contains a unique code that forms an exclusive combination with the license plate and VIN in the backend database. When passing through toll stations, RSU sensors capture this pairing information with scanner-like precision. If multiple OBUs are registered to one vehicle, the system triggers anti-fraud protocols upon detecting dual signal sources. When helping a friend transfer a used ETC device, I discovered that DMV systems retain binding records for three months even after hardware removal. Therefore, proper cancellation procedures are mandatory for new card activation - otherwise the system keeps reporting information conflicts. Rather than attempting dual ETC setups, it's wiser to check if leakage caused the old device's malfunction.

Managing ETC is like handling a SIM card - one device, one number is the ironclad rule. Last week, I accompanied a colleague to the bank and witnessed the teller entering his license plate number into the system, only for a red warning box to pop up. It turned out the ETC he deregistered from his old car three years ago was still in the cooling-off period. The staff explained that each vehicle's file has dedicated space in the Ministry of Transport's cloud server. Applying for a new ETC is like putting items in a cabinet - when it's full, you can't squeeze in a second one. I recommend owners needing deregistration to directly call the 95022 service hotline, which is much faster than visiting branches. Last year when I sold my car, I handled it via - after the customer service remotely unbundled it, the new owner could apply for a card the same day. Never believe scalpers claiming they can illegally process dual ETCs. Losing money is minor, but getting blacklisted from highways would be disastrous.

As a seasoned driver who has used seven ETC cards, I recommend treating the device as your vehicle's exclusive ID card. The Ministry of Transport's regulations are crystal clear: each motor vehicle can only be bound to one valid electronic tag. My younger brother learned this the hard way last year when he secretly applied for a second ETC card using his wife's ID—the device was deactivated immediately upon activation, with both accounts automatically frozen by the system. It took him half a month of running to the bank and signing affidavits to get them unfrozen. Actually, applying for a new device is very convenient—my ICBC card arrived via free mail in just three days. When transferring vehicle ownership, remember three key steps: first cancel the original ETC, then remove the old device, and finally bring the new vehicle certificate to the bank for registration. Also, try to park away from direct sunlight—this can extend your OBU device's lifespan by three to five years.
