Is ETC universally compatible?

[Aria]

ETC is universally compatible across the country and achieved nationwide network connectivity as early as 2015. According to the State Council's regulations, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, requiring payment through manual channels. Additionally, newly installed ETC devices cannot be used immediately on highways; they need to be activated first. During holiday free periods, ETC users can still use highways, and passing through ETC lanes will not incur charges. ETC Deduction Principle: 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, computer networking technology is used for 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 toll stations without stopping, reducing noise and exhaust emissions. Reduced wear and tear: Saves costs by minimizing frequent starts and brakes, lowering vehicle wear and fuel consumption. Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC faster and more high-tech. 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 Comprehensive Transportation System" explicitly states the goal of "achieving interoperability of transport cards in key city clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020." More future possibilities: Beyond improving ETC installation convenience and passenger vehicle usage rates, future efforts will promote ETC use for trucks and explore deeper integration of ETC systems with smart transportation developments like vehicle-to-vehicle communication and vehicle-road coordination. This will provide comprehensive travel services for car owners, meaning more application scenarios will support ETC. ETC Usage Notes: The ETC transaction sensing range is 8 meters. If the vehicle ahead is stationary, maintain a distance of over 10 meters to avoid automatic payment for the preceding vehicle due to ETC device failure or absence. The ETC lane recognition speed is 20 km/h. Excessive speed may prevent reading vehicle device information, leading to failed deductions. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or loosens, will render the tag invalid. It can be taken to the bank where the ETC card was issued or a highway service center for inspection. Non-deliberate loosening or detachment only requires reactivation. When using a debit card linked to ETC, insufficient balance may cause deduction failure. Follow on-site staff guidance to use manual MTC lanes with cash or card payments. Overly thick windshields may cause poor sensing, especially for vehicles with replaced or modified windshields after accidents.
