Why did the ETC deduction fail?
2 Answers
There are two scenarios for unsuccessful ETC toll deduction on highways: One is caused by damaged barriers where vehicles pass through ETC lanes at excessive speed, resulting in failed deductions; the other involves deferred ETC billing, meaning charges are not immediately deducted but processed within a designated billing cycle. ETC Usage Precautions: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of over 10 meters to prevent automatic fee payment for the preceding vehicle in case its ETC device malfunctions or is absent. The recognized speed limit for ETC lane passage is 20km/h. Exceeding this speed may prevent reading vehicle device information, leading to deduction failures. Unauthorized removal or displacement of OBU devices, detached or loosened ETC electronic tags will deactivate the tags. These can be inspected at the bank where the ETC card was issued or highway service centers. Non-intentional loosening only requires reactivation. Insufficient balance on debit cards linked to ETC may also cause deduction failures. Follow on-site staff guidance to use manual MTC lanes with cash or card payments. Excessively thick windshields may impair signal reception, particularly for vehicles with replaced windshields post-accident or modified front windshields.
As a veteran driver with over 20 years of experience, I once felt extremely anxious when my ETC failed to deduct the toll on the highway. It turned out the small box of the onboard device had run out of battery, especially since high summer temperatures drain batteries faster. Other common issues include driving too fast (signal capture failure), loose or improperly inserted cards, and account problems like insufficient balance or expired credit cards. You can check transaction records on the app, and regular device maintenance can prevent these issues. Failed deductions may lead to subsequent penalty risks, so prompt action is essential. I recommend checking your device status monthly and confirming sufficient balance before long trips. If this happens on the highway, stay calm, pull over safely, and contact a service point.
