Speed Change Lanes are defined as acceleration or deceleration lanes for left or right turns, exit or entrance acceleration or deceleration lanes, or climbing lanes.

A design waiver is required for speed change lanes that do not meet minimum length and width criteria.

See for design guidance on speed change lanes.

Where passing lanes are provided in the vicinity of intersections, appropriate separation between the extents of passing lanes and turning lanes should be provided based on the guidance from . The beginning or end of a passing lane should be

at least 1,000 ft upstream

of an intersection and

at least 1,500 ft downstream

of an intersection to avoid introducing intersection delay associated with the interactions of the minor-road vehicles turning on the major road and those vehicles merging at the end of the passing lane. Refer to for guidance that includes the consideration of appropriate sight distance at the intersection, as referred to in .
