What Are the Reasons for the ETC Barrier Not Lifting When Entering the Highway?

Reasons for the ETC barrier not lifting when entering the highway include detachment or removal of the ETC device; ETC device malfunction; lane malfunction; pass card malfunction; or being blacklisted. In such cases, it is necessary to promptly contact on-site staff for assistance. How ETC Works: Through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, computer networking technology is used to perform backend settlement processing with the bank. This allows vehicles to pass through highway or bridge toll stations without stopping while still paying the toll. ETC Usage Notes: The ETC transaction sensing range is 8 meters. When encountering a vehicle in front that has stopped, to prevent the front vehicle's ETC device from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters to avoid automatic sensing and payment for the front vehicle. The ETC lane recognition speed is 20 km/h. If the vehicle speed is too fast, the vehicle device information cannot be read, which will also result in payment failure. Unauthorized removal or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for testing. Non-deliberate loosening or detachment only requires reactivation. When using a debit card linked to ETC, insufficient balance will also cause payment failure. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Excessive thickness of the car windshield can cause poor sensing. This is especially important for vehicles that have had their windshields replaced after an accident or for those who have modified their front windshields.
It's really frustrating when the ETC barrier doesn't lift while driving on the highway. Common reasons include issues with the OBU device, such as a dead battery or incorrect placement on the windshield. Sometimes, driving too fast or following the car in front too closely can prevent the sensor from recognizing the device in time, causing it to malfunction. Secondly, insufficient account balance or a frozen account will also trigger the system to refuse lifting the barrier. Lane malfunctions, such as dirty sensors or heavy rain interference, are another possible factor. If this happens, don't panic—reverse to a safe position and try again. If it still doesn’t work, immediately close the window, turn on hazard lights, and seek manual assistance from staff to avoid fines or trouble. Regularly check whether the tag is properly activated, monitor battery status, and ensure account top-ups to prevent such inconveniences from disrupting travel plans. If the issue persists, it's best to visit an ETC service center to replace the device.
I've encountered many cases where the ETC barrier doesn't lift. The main reasons include malfunctioning OBU equipment, depleted batteries, or poor contact. Signal reception issues are also common, caused by strong light or metal objects interfering with the antenna. Account problems shouldn't be overlooked either, such as insufficient balance or expired tags not being renewed. Improper driving behavior plays a role too - exceeding the 20km/h speed limit or tailgating can prevent lane scanners from accurate detection. Safety measures are crucial: don't block the entrance, slowly reverse and pull over, call staff for assistance, or use manual card payment. For prevention, choose an optimal OBU installation location avoiding blind spots, check your account status and tag validity monthly. Before long trips, conduct a simulated barrier test. Spending time on these small precautions can prevent dangerous highway entrance delays.
