What does a lane reversal sign indicate?

Answer: A — Traffic in the lane is switching directions

A lane reversal sign indicates that traffic in that lane is switching directions. This situation often arises in specific conditions, such as during peak travel times on certain roads where traffic flow needs to be adjusted to manage congestion more effectively. Typically, such a sign will be used in conjunction with temporary traffic signals or cones to signal drivers about the change in the usual flow of traffic. Understanding this concept is crucial for safe driving, as it helps drivers anticipate changes in road usage and react appropriately to avoid accidents or confusion.
