What is the purpose of the center lane along West Bay Road?

The purpose of the center lane along West Bay Road is primarily to act as a turning lane. This lane is designated for vehicles to safely enter and exit from the road at designated points, allowing drivers to make left turns onto side streets or into parking areas. By having a separate turning lane, traffic flow is improved, reducing the risk of accidents that can occur when vehicles stop in a through lane to make a turn. This helps to keep the main lanes clear for those who are continuing straight, thereby enhancing the overall safety and efficiency of the roadway.

The other options, while they may serve specific functions in different contexts or roads, do not accurately describe the designated use of the center lane on West Bay Road. A parking area is meant for stationary vehicles, a bus lane is specifically reserved for public transport, and a bike lane is intended for cyclists; none of these functions align with the purpose of the center lane as a turning lane.
