50 Description A right-turn lane is an auxiliary lane provided to allow right-turning vehicles to conduct most of their deceleration and, if necessary, queue before making their turn. The technique of widening the right through lane to better accommodate right turns from driveways is also included as part of this group.

Right-Turn Lanes 53 Right-turn lanes that are too short to accommodate demand or that otherwise provide insufficient deceleration distance result in a greater speed differential between right-turning vehicles and through vehicles relative to the typical design differential of 10 mph (1)

54 Guide for the Analysis of Multimodal Corridor Access Management Bus Operations A simulation study (9) found that right-turn deceleration lanes increased bus delay at near-side stops at traffic signals in the range of 0.6 to 4.1 seconds, depending on the right-turn lane length, traffic signal cycle length, bus dwell time length, and vehicular volumes.
