How to Read Traffic Signals in Variable Lanes?
2 Answers
There are also text prompts on the ground to remind drivers to choose their desired lane in advance according to the traffic signals. Once entering the solid line area of a variable lane, drivers must not cross the solid line to change lanes arbitrarily, nor proceed straight when the left-turn signal is on or turn left when the straight signal is on. They must follow the direction indicated by the traffic signals.
After commuting by car for so many years, passing through variable lanes daily, just watch the overhead signals: the large arrow indicators above the lane. A green arrow pointing left or right means the lane is open in that direction; stop and wait when it's red. During peak hours, changes happen quickly, so I’ve gotten used to slowing down early, leaving a safe distance, and glancing at the arrow changes out of the corner of my eye. On rainy or foggy days with poor visibility, I turn on my headlights from farther away to help see clearly. The signal system adjusts intelligently based on traffic flow—more straight lanes in the morning rush, switching to left turns in the evening. I often remind friends to stay calm, avoid tailgating, and not miss signal changes. During city congestion, navigation apps can also help by alerting you in advance about lane signal adjustments.
