What is the function of an acceleration lane?

The function of an acceleration lane is to increase speed from one public road to another. This type of lane is designed specifically to help vehicles gain the necessary speed to merge safely onto a faster-moving roadway, such as a highway or expressway. By providing a dedicated space where drivers can accelerate without impeding the flow of traffic, acceleration lanes enhance the safety and efficiency of merging vehicles.

As vehicles enter the acceleration lane, drivers have the opportunity to adjust their speed to match that of the vehicles already on the highway, reducing the likelihood of sudden stops or collisions. This smooth transition is crucial for maintaining the flow of traffic and ensuring that drivers can enter the main roadway safely and effectively. The other options do not align with the primary purpose of an acceleration lane, which is to facilitate smoother merging rather than addressing pedestrian traffic, stopping, or parking.
