ETC lane entry and ETC lane exit: No fee deducted. Manual lane entry and manual lane exit: No fee deducted. Manual lane entry and ETC lane exit: No entry information, exit barrier won't lift. ETC lane entry and manual lane exit: Passable without fee deduction. ETC Working Principle: Through dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, combined with computer networking technology for backend bank settlement, vehicles can pass highway or bridge toll stations without stopping to pay fees. Benefits of Installing ETC: Saves time by eliminating the hassle of waiting in queues. Environmentally friendly: Vehicles pass toll stations without stopping, reducing noise and exhaust emissions, thus minimizing pollution. Reduces wear and saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption. Users also enjoy a 5% discount on toll fees. Improves efficiency: ETC lanes can theoretically increase vehicle passing efficiency by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
As an experienced driver who frequently travels on highways, I’d like to share some tips: For ETC vehicles passing through highways during free periods like holidays, the easiest way is to directly enter the ETC-only lane. The system will automatically recognize the free passage, and the barrier will lift to let you through. The key is to ensure the device is securely installed, the card is firmly inserted without loosening, and the battery is fully charged—otherwise, a mid-journey failure could lead to being stopped and hassled. I recommend downloading a highway app before your trip to check real-time free periods and lane status. During peak hours, like the eve of National Day, traffic is heavy, and using the ETC lane can help avoid long queues at manual toll booths. Also, pay attention to the free period’s end time—if you enter the highway just before it ends, you might still be charged upon exit. So, plan your trip wisely and avoid rushing at the last minute—safety first, with peace of mind as a bonus.
I focus on technical details: The key to ETC vehicles' free passage is the proper functioning of the equipment. During free periods, toll stations switch to a no-charge mode, and vehicles are let through once detected by microwave sensors. You don't need to do anything—just head straight for the ETC lane. Normally, I make it a habit to check that the ETC device's green light is on and the battery is sufficiently charged to avoid signal issues on rainy days. If you enter before the free period ends, the system records your entry time, and if you exit while still within the free period, you're fully exempt. The entire process is automated and highly efficient. I always travel during off-peak hours to reduce congestion and unexpected situations, which also helps save power.
