Can the ETC card be removed after entering the highway?

[LaylaLynn]

The ETC card can be removed, but the ETC device will not function without it. You can reinsert the card before exiting the highway. According to the "Rules for the Use of the Non-Stop Express Pass System," the ETC card must be inserted into the OBU device for normal operation; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card. When the ETC card is inserted into the OBU device, a prompt sound will indicate that the device is activated. Without the card, the device remains in a dormant state and cannot recognize vehicle information at toll stations. ETC is an electronic toll collection system, also known as an automatic road toll system. It is a specialized method for collecting tolls on roads, commonly used on highways, toll bridges or tunnels, and certain urban sections to alleviate traffic congestion. ETC Deduction Principles: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's onboard electronic tag (installed on the windshield) and the microwave antenna in the ETC lane, the system uses computer networking technology to settle payments with banks, allowing vehicles to pass toll stations without stopping. This operates on a "pass first, deduct later" principle. Benefits of Installing ETC: Time-saving: Eliminates the need to queue and wait. Green and eco-friendly: Reduces noise and exhaust emissions by minimizing stops at toll stations. Cost-saving: Lowers wear and fuel consumption by reducing frequent starts and stops. Improved efficiency: ETC lanes can theoretically process vehicles 2-3 times faster, making traditional ETC more advanced, faster, and 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 transportation cards in key urban 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." Future possibilities: Beyond improving the convenience of ETC installation and increasing its usage rate, future efforts will promote ETC adoption for trucks and explore deeper integration of ETC systems with smart transportation developments like vehicle-to-vehicle communication and vehicle-to-infrastructure coordination. This will provide comprehensive travel services for car owners, meaning more application scenarios will support ETC usage.
