Is It Normal for ETC to Flash Green Light?

[SanArthur]

It is normal for the ETC sensor to flash a green light when the vehicle is running, indicating that the sensor is detecting. The following are the specific functions of ETC: 1. Time-saving: Vehicles passing through the ETC lane only take 2 to 3 seconds, eliminating the need to queue for payment. In contrast, traditional manual toll lanes, based on normal traffic flow, take 20 to 120 seconds for vehicles to enter the lane, wait, and complete the toll payment process. 2. Fuel-saving: Since vehicles using ETC can pass without stopping, the frequency of vehicle starts and brakes is reduced, lowering fuel consumption and vehicle wear. 3. Cost-saving: By using ETC, drivers can enjoy a 5% discount on toll fees in many places. 4. Environmental protection: With ETC, reduced fuel consumption and vehicle wear naturally lead to lower exhaust emissions and less environmental pollution.
