What does it mean when the ETC displays license plate detection for the first time on the highway?

It is checking whether the license plate meets the standards. If the license plate does not comply, the vehicle cannot pass. Below is some relevant information about ETC: 1. Definition of ETC: The Chinese translation is electronic toll collection, which is an automatic toll collection system for highways or bridges. It uses dedicated short-range communication between an onboard electronic tag installed on the vehicle's windshield and a microwave antenna in the ETC lane of a toll station. By leveraging computer networking technology and backend bank settlement processing, vehicles can pass through highway or bridge toll stations without stopping to pay the toll. 2. Technical Principle: The ETC system employs automatic vehicle identification technology to complete wireless data communication between the vehicle and the toll station, enabling automatic vehicle recognition and the exchange of relevant toll data. It uses computer networks to process toll data, achieving a fully automatic electronic toll collection system without the need for stopping or toll booths.
Don't panic when you see the ETC displaying license plate detection on the highway for the first time. This is the highway gantry automatically verifying your license plate information. The ETC system not only relies on the device in the card but also uses cameras to capture the license plate number for dual verification. This mainly prevents people from using someone else's ETC card to evade tolls or cases of cloned license plates. Last time I went on a long trip, I encountered it—the gantry flashed, and a license plate detection prompt popped up on the dashboard. At this point, just maintain normal speed and avoid sudden braking or lane changes, as it might affect the accuracy of toll deduction if the system fails to recognize clearly. If this prompt appears frequently, it might be due to a dirty license plate or incorrect ETC device placement—remember to check it after exiting the highway.
The license plate detection prompt is a routine verification action performed by the ETC system on highways for your vehicle. High-definition cameras on the gantries capture the license plate information, which is then matched with the data bound to the ETC card. I think this design is quite user-friendly, as it helps avoid many disputes. For example, when you rent a car and drive on the highway, the cameras recognize the rental company's license plate, and the system can automatically match it with the bank card registered during the rental for fee deduction. Additionally, cloned license plates become easily detectable under such a system. However, it's important to ensure the clarity of the license plate; dirt or damage can lead to recognition failures, especially on muddy roads after rain, so it's advisable to wipe the plate clean frequently.
