What is the correct term for a lane where vehicles are accelerating and decelerating, typically found on entrance or exit ramps?

The term that accurately describes a lane where vehicles are accelerating and decelerating, particularly on entrance or exit ramps, is "acceleration lane." An acceleration lane is designed for vehicles to increase their speed to match that of traffic on the main highway when merging. It provides a safe area for drivers to gain the necessary speed to enter the flow of traffic smoothly without disrupting the flow of vehicles already traveling at high speeds.

On the other hand, a "weave lane" is designed for vehicles to both enter and exit the highway at the same point, creating a situation where vehicles must negotiate merging and diverging traffic in the same area. This type of lane can be complex and requires careful attention from drivers to avoid accidents.

Therefore, recognizing the purpose and function of an acceleration lane helps clarify why it is the appropriate answer for this question since it specifically denotes a lane intended for speeding up, rather than weaving or other traffic patterns.
