Editing Lane (section)

===Entering and exiting===

*{{anchor|turn lane}}Dedicated '''turn lanes''' can be used to allow through traffic to avoid waiting for turning traffic at intersections, at the expense of increased roadway width for pedestrians to hazard. Some turn lanes have signals that prevent turns when pedestrians or bicycles are allowed to proceed. On high-speed roads, turn lanes can improve safety by providing a separate lane for traffic that needs to slow down.
* A '''[[slip lane]]''' (UK: '''filter lane''') allows vehicles to bypass an intersection and take an unsignalized turn when crossing traffic is not required (for example a right-hand turn for right-hand traffic). Yielding to traffic on the cross street is typically required.
* An '''acceleration lane''' or '''merge lane''' allows traffic entering a highway to accelerate to the speed of through traffic before merging with it.
* A '''deceleration lane''' is a lane adjacent to the primary road or street used to improve traffic safety{{citation needed|date=February 2023}} by allowing drivers to pull out of the through lane and decelerate before turning off a surface street or exiting a highway or motorway.
* An '''operational lane''' or '''auxiliary lane''' combines an acceleration and deceleration lane, running the entire length between an entrance and exit. The lane is created when an entrance ramp meets the highway, and drops out (with an "exit only" sign) to become the ramp at the next exit.{{citation needed|date=October 2022}}
