The method to check if ETC is working is: 1. Remove the ETC card; 2. Reinsert the ETC card into the electronic tag; 3. After hearing a beep sound, when the electronic tag screen displays "Toll Card" or the amount, it proves that the ETC is in normal working condition. ETC is an automatic toll collection system for highways or bridges. It uses dedicated short-range 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. By utilizing computer networking technology and bank backend settlement processing, it achieves the purpose of allowing vehicles to pass through highway or bridge toll stations without stopping to pay the fees.
I've been driving for many years, and checking whether the ETC is functional involves several aspects. The most straightforward method is to find an ETC lane on the highway and give it a try—if the toll barrier automatically lifts, it means it's working. However, there's no need to make a special trip to the highway for this. I usually check the status light on the OBU device: a blinking green light indicates normal operation, while a constant light or no light may signal a device malfunction. Additionally, I have the local ETC official app installed on my phone, which allows me to check the status anytime after linking my vehicle, such as whether the account balance is sufficient or if the device is activated. I also regularly inspect the card slot to ensure smooth insertion and removal and check for any rust that might cause poor contact. The placement of the device is crucial too; overly thick window tint or metal obstructions can interfere with signal transmission. If I'm still unsure, I visit the ETC service center for a professional device test.
Driving on the highway every day, I've developed a set of ETC inspection routines. Before setting off, I insert and remove the card to confirm there's a beep—no sound usually means the card or device has an issue. Many OBU devices now come with Bluetooth functionality, allowing you to check the device status via a mobile app, which is super convenient. When passing through an ETC lane, I check the rearview mirror to confirm the barrier reacts—sometimes driving too fast or tailgating can prevent the barrier from lifting. I also check the deduction records of the linked bank card monthly to ensure automatic payments go through. Another trick is testing at ETC-enabled parking lot exits, which is easier than doing it on the highway. If the device light turns red or malfunctions frequently, it's time to address the issue promptly.
