Why is the ETC tag expired?
1 Answers
The reasons for the ETC card expiration may include self-removal or relocation of the OBU device, ETC power depletion, or detachment/loosening of the ETC electronic tag. Below are relevant details about ETC: 1. Installation position: Height should be no less than 1.2 meters and no more than 2.5 meters. The installation angle N should be between 30º and 90º (the angle between the electronic tag surface and the horizontal plane). 2. Transaction position: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, to prevent issues with the preceding vehicle's ETC device or absence of an ETC device, maintain a distance of more than 10 meters to avoid automatic fee deduction for the preceding vehicle.
