What is the purpose of a deceleration lane?

The purpose of a deceleration lane is to provide a designated space for drivers to slow down safely as they prepare to exit from a busy roadway. This lane is specifically designed to facilitate a gradual decrease in speed, helping to prevent sudden stops or abrupt speed changes that could create hazardous conditions for both the exiting vehicle and those continuing on the main road. By having this dedicated lane, drivers can transition from high-speed traffic to the lower speeds required for safe navigation of intersections or other public roads, enhancing overall traffic flow and safety.
