ETC cannot be used due to the following reasons: 1. Insufficient battery power of the ETC device causing it to fail to start; 2. The ETC electronic tag is invalid; 3. The vehicle's speed is too fast when passing through the ETC lane, making it impossible for the system to read the information; 4. Failure to deduct fees due to reasons such as ETC lane reading failure or insufficient balance on the ETC card; 5. Malfunction of the OBU (On-Board Unit) device, which can generally be resolved by reactivating it. ETC is an Electronic Toll Collection system, also known as an Automatic Road Payment System. It is a road toll method specifically designed for toll roads, commonly seen on highways, bridges or tunnels with toll policies, and certain sections of urban areas to alleviate traffic congestion.

I drive frequently and have experienced ETC failures several times. The most common issue seems to be device-related, such as a dead battery in the ETC card or card damage. I've tried checking it myself: first, see if the OBU box has a green light on. If it's red or completely unresponsive, it's time to consider replacing the card. Installation problems can also interfere, like metal film on the windshield disrupting the signal—I had this issue before and had to remove the film to fix it. Account status is crucial too; insufficient balance or a bank freeze can lead to payment rejection, which can be checked via the app. Occasionally, toll station equipment malfunctions can cause read failures, so I switch to cash lanes in those cases. I recommend regular maintenance, like cleaning the card surface every six months and testing it before hitting the highway to avoid delays at the gate. From a safe driving perspective, ETC failure isn't trivial—getting stuck at a highway entrance could cause accidents. The best solution is to quickly visit a service point or contact customer support.

As a tech enthusiast, I've thoroughly studied how ETC works. It relies on radio frequency signals for reading, and when issues arise, they usually boil down to three points: device malfunctions like aging internal circuits in the OBU unit causing signal failure; wiring problems such as loose vehicle cables, especially on bumpy roads where connections may break; and strong external interference, like nearby electromagnetic fields affecting performance. While repairing cars, I've noticed many overlook issues like dust accumulation in the card slot or overly thick films—simply wiping with a soft cloth might fix it. On the account side, I've found that bank systems often freeze ETC due to delayed payments, which can be resolved by checking the status via the app. Weak signals are another common factor, like aging toll booth antennas or read failures during rain or fog. I once solved this by driving to a service area and restarting the device. For prevention, I make it a habit to regularly update the system or replace cards to avoid problems with expired devices.

We have a commuter car at home, and the ETC is used for convenience. Finding it unusable is usually a minor issue. First, check if the card is properly inserted—once I was in a hurry and the card was loose, so it didn't respond. Secondly, battery issues are common; ETC cards tend to run out of power after two or three years and need replacement. An account balance deficit can also lead to payment rejection, so checking your balance via mobile banking and topping up in time solves the problem. Dark tinted films on the windshield can block signals—mine worked fine after I changed the film. Daily maintenance tip: I clean the card surface monthly to prevent poor contact. Weather has a big impact; weak signals and failed readings during rain or snow are normal. When toll station equipment malfunctions, I switch to the manual lane to pay. Overall, don’t stress—most issues can be handled yourself. If all else fails, visit a service point to check the device, so you don’t miss picking up the kids from school.

I frequently travel on highways for business trips, and ETC malfunctions can disrupt my schedule. Common causes can be categorized into hardware and software issues: hardware problems include aging or damaged OBU devices or misaligned installation angles that prevent signal transmission; software issues involve account freezes or system deactivation due to unpaid fees. My troubleshooting sequence: first, check if the card light shows abnormal status, then verify whether the windshield film blocks the signal; using a mobile app to check account status is quick and accurate. Environmental factors like prolonged exposure to high temperatures can cause device failures—I keep a small fan in my car for cooling, which has helped. Prevention tips: regularly test the card by activating it in low-speed zones to ensure functionality. If stuck at a toll station, I immediately turn on hazard lights, pull over, and contact the highway service hotline for assistance, prioritizing safety over forcing through. Addressing the issue promptly prevents delays.
