What are flex lanes?

Flex lanes are designed to adapt to varying traffic conditions by allowing the direction of traffic flow to change as needed. This flexibility helps to optimize roadway use, particularly during peak traffic times. When traffic is heavier in one direction, the lane can be configured to accommodate more vehicles traveling that way, thereby reducing congestion. Conversely, when traffic conditions permit, the lane can be used for the opposite direction. This adaptability makes flex lanes a valuable tool in managing roadways efficiently, enhancing safety, and improving overall traffic flow.

The other options describe specific lane uses or restrictions but do not capture the dynamic nature of how flex lanes operate in response to real-time traffic demands.
