What is the difference between yellow and green ETC?
2 Answers
Highway yellow ETC is the normal lane for most vehicles. Green ETC is the green channel without restrictions. The following is an introduction about highway toll station ETC: 1. Introduction: Highway toll station ETC is a term for the electronic toll collection system without stopping. It uses automatic vehicle identification technology to complete wireless data communication between vehicles and toll stations, automatically identifies vehicles and exchanges relevant toll data, processes toll data through computer networks, and achieves a fully electronic toll collection system without stopping. 2. Principle: The ETC lane refers to the dedicated lane for electronic toll collection without stopping. The ETC non-stop toll collection system uses microwave dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna on the ETC lane of the toll station, and uses computer networking technology to conduct background settlement processing with the bank, thereby achieving the result that vehicles can pay tolls without stopping when passing through road and bridge toll stations.
To be honest, after driving for so many years, I've noticed that the main difference between yellow and green ETC lanes lies in their usage rules. The green lane is the standard electronic toll collection channel, allowing any vehicle regardless of passenger count to pass through quickly – extremely convenient. The yellow lane is different; it's actually an HOV (High-Occupancy Vehicle) lane, requiring at least two passengers in the car for usage, otherwise you might get fined. Why this distinction? Highways often get crowded, and the yellow lane encourages carpooling to reduce single-vehicle congestion while being more environmentally friendly and fuel-efficient. Every time I drive on the highway, I have to glance at the signs – green lanes mean direct card payment, while yellow lanes require confirming passenger count. A wrong entry could mean a 200-yuan fine. New drivers especially tend to get confused, so I recommend using navigation apps that indicate lane types – safety first. Taking the wrong lane not only wastes time but can also be dangerous.
