The function of the deceleration lane when exiting an expressway is to allow drivers to safely reduce their speed and yield to other vehicles. This lane is specifically designed as a transitional area where drivers exiting the highway can gradually decrease their speed before they reach the intersection or merge into a lower-speed roadway. This is crucial for maintaining safety, as sudden reductions in speed while still on the expressway could lead to accidents. By using the deceleration lane, drivers can better gauge the traffic conditions as they prepare to enter the next road, ensuring they can yield appropriately to any oncoming traffic.

The other choices do not accurately represent the primary purpose of a deceleration lane. For instance, increasing speed before merging contradicts the need for reduced speed when exiting. Providing parking space and allowing turning around are not relevant functions of a deceleration lane, which is solely focused on facilitating a controlled and safe transition from a higher-speed environment to a lower-speed area.
