Can One Person Only Have One ETC per Car?

One person can apply for multiple ETCs. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Expressways" issued by the Ministry of Transport, the application for ETC is related to the vehicle's driving license. If you own multiple vehicles, you can use different driving licenses to apply for ETCs. Documents required for ETC application: Original valid ID card of the vehicle owner, original and photocopy of the vehicle driving license (the page with the latest annual inspection stamp). If applying on behalf of someone else, the original valid ID card of the agent is also required. If applying for ETC through major bank branches, a debit or credit card from the corresponding bank is needed. Some banks only support ETC binding with credit cards, while others may require freezing a certain amount as a deposit when binding with debit cards. The current year's vehicle insurance policy is also required. For corporate applications, the agent's ID card (or driver's license), the company's organization code certificate (or business license), and the official seal are needed. ETC charging principle: There will be one or more ETC lanes on the expressway. Through the dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with the bank, the vehicle can pay the toll without stopping at the toll station. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; 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, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can improve vehicle passing efficiency by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also set the goal of "achieving a 50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of the "13th Five-Year" comprehensive transportation development. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation development directions 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 stationary vehicle ahead, 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 recognized speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, leading to charging failure. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, 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 detachment is not man-made, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also cause charging failure. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Thick car windshields may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.

As a seasoned driver with many years of experience, I can tell you that a car can indeed only have one ETC device installed. This is because the ETC system relies on the license plate to identify the toll device. If you install two or more on the same car, it will cause conflicts, leading to incorrect charges or unrecognized payments. A friend of mine personally experienced this when they wanted to apply for a spare one, but the bank refused registration. However, an individual can have multiple cars, and it's fine to apply for different ETC devices for each car. If the device is broken, you have to go to the ETC center to cancel the old one before applying for a new one. Overall, one ETC is convenient enough—it saves time when passing through highway toll gates, so why bother with more? Regularly checking the device's battery is also important.

I'm someone very interested in automotive electronic systems. The working principle of ETC is that the device communicates with toll stations via radio waves for payment, so only one active ETC device can be activated per vehicle. The license plate serves as the unique binding point in the system and cannot be registered with multiple devices; otherwise, the system would confuse the toll data. I've tried simulating adding a new device to the same car, but the system directly reported an error and refused. This design is to prevent toll payment loopholes. Want to register two sets personally? Technically not possible, but you can have one ETC per vehicle. Remember, keep the ETC device away from strong magnetic interference areas to ensure normal operation—one is enough.

I understand that in terms of traffic regulations, a motor vehicle can only have one valid ETC device, which is a mandatory rule set by the transportation department. During personal registration, the system automatically checks the license plate, and if there is a duplicate, the registration cannot proceed. Therefore, only one device can be installed in a car; having more is a violation and may cause trouble. I recommend everyone to follow this rule for smoother highway passage. Regular maintenance of the device connection is also crucial.

What causes noticeable jerking when shifting into reverse gear?

Noticeable jerking when shifting into reverse gear is typically caused by transmission issues, specifically clutch plate slippage. Here are the related causes: 1. Damage to the reverse gear synchronizer. Solution: Repair or replace the reverse gear synchronizer. 2. Damage to the reverse gear teeth, such as broken or chipped teeth. Solution: Repair or replace the reverse gear teeth. 3. Damage to the reverse gear bearing, or poor bearing lubrication causing friction noise. Solution: Repair or replace the bearing. 4. Releasing the clutch too quickly. Try shifting at 3000 RPM - the jerking will be significantly reduced. When downshifting, wait for the RPM to drop before shifting.

Why does the Honda CR-V cool down slowly?

It is common in daily life for the Honda CR-V to have slow cooling. Excessive dirt in the air conditioning refrigerant: Increased resistance reduces the flow of refrigerant to the expansion valve, leading to ineffective cooling of the car's air conditioning system. Air entering the air conditioning system: Once air enters, it can cause excessive pressure in the refrigerant lines and poor refrigerant circulation. This type of fault mainly occurs due to degraded sealing of the cooling system or incomplete vacuuming during maintenance. Reduced heat dissipation capacity of the condenser: Due to varying working environments, the condenser located in front of the car's engine can become covered with oil, dirt, or debris, thereby reducing its heat dissipation capacity.
