What are the three areas that make up an expressway entrance lane?

An expressway entrance lane typically consists of three key areas: the deceleration lane, the merge lane, and the acceleration lane. The deceleration lane allows vehicles to safely reduce speed before entering the expressway. The merge lane facilitates the transition of vehicles from the entrance onto the expressway, while the acceleration lane provides space for vehicles to increase their speed to match the flow of traffic. These components work together to ensure a smooth and safe entry onto the expressway.
