After installation and activation, the ETC device remains in an always-on state. It can be turned off when not in use, but it must be turned on in advance before driving on highways. ETC devices generally have built-in batteries and solar panels to maintain sufficient power. ETC stands for Electronic Toll Collection, which is an electronic toll system. To apply for ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If the application is handled by someone other than the owner, the agent's valid ID card must also be provided. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is required. Applicants must be between 18 and 60 years old and the vehicle must be registered under their name. How ETC works: The vehicle-mounted electronic tag installed on the windshield communicates with the microwave antenna in the ETC lane at the toll station. The system uses computer networking technology to settle payments with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay the toll. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Reduces noise and exhaust emissions as vehicles pass through toll stations without stopping; Cost-saving: Reduces the frequency of vehicle starts and stops, minimizing wear and tear and fuel consumption. Users can also enjoy toll discounts; Increased efficiency: ETC lanes can theoretically improve traffic efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

As a seasoned driver with years of experience, I can tell you from practical knowledge that the ETC device in your car doesn't need to be deliberately kept on all the time, but it's advisable to leave it on standby. Most ETC units installed in vehicles come in the form of electronic tags, powered by batteries or the car's electrical system, and are designed with a low-power mode that consumes minimal electricity when idle. Personally, I never turn mine off while driving because it automatically wakes up and activates at toll booths, eliminating the hassle of manual operation. Importantly, if you do turn it off, you might have to stop and queue to pay with cash at toll stations, which not only wastes time but also increases the risk of congestion. After installation, remember to periodically check the or wiring to prevent it from failing due to power loss. Overall, keeping the ETC on is convenient, and there's no need to frequently switch it on and off—just make it a habit, as it's ultimately a tool meant to save you time and hassle.

From a technical perspective, the ETC system in cars is based on RFID wireless communication, with its core functionality relying on sensors to automatically read information at toll stations. As someone who dabbles in automotive technology, I believe it doesn't require constant manual switching on/off, but the hardware should remain powered to stay in standby mode. This system has extremely low power consumption - leaving it on doesn't waste electricity, whereas turning it off might cause missed toll booth recognition. For highway sections specifically, keeping it operational is mandatory to avoid payment failures or unnecessary fines. During installation, I recommend having professionals check the wiring to ensure stable continuous operation. That said, if the vehicle won't be used for extended periods (e.g., several months), disconnecting it may be wise to prevent drain. Ultimately, for optimal efficiency, keeping it active is the most sensible approach - don't let minor concerns compromise major functionality.

I mainly drive to pick up and drop off my kids at school, so I'm quite familiar with ETC operations. Actually, it doesn't require us to manually keep it on all the time - the onboard device is usually automatically activated. Normally when driving, I don't touch it at all; it only responds at toll stations. The relevant point is that having ETC enabled helps me pass through quickly, avoiding stopping in queues, which is especially reassuring during heavy traffic. The power consumption is minimal, and turning it off might actually cause you to forget to turn it back on, leading to issues. My personal suggestion is to test it properly after installation and then leave it be - this approach is both safe and convenient.

From an economical and practical perspective, I focus on car expenses. Keeping the ETC device on basically adds no extra cost because its power consumption is minimal and negligible. The biggest advantage of keeping it on is saving time and fuel when passing through highways, avoiding additional fuel consumption from stopping to pay in cash. Relatedly, it's important to choose a reliable brand during installation to ensure compatibility. Keeping it on is a cost-effective choice; if turned off at a toll station, it could lead to hassle and possibly higher fees. Overall, maintaining the ETC in an active state is most beneficial for efficiency and cost control.

As a new driver, I'm a bit curious about how ETC works. After asking friends, I learned that there's no need to manually turn it on/off frequently - it's designed to operate automatically in an always-on mode. Normally I just leave it alone while driving, and it only activates automatically when passing through toll stations. Key points include keeping it powered after installation to avoid manual operation errors. Keeping it on is perfectly safe, doesn't interfere with driving, and is especially worry-free for beginners. It's recommended to perform regular checks to ensure proper functioning and avoid minor malfunctions.
