"Bicycle Left Turn Must Use Turn Box, MUTCD" (Part#: SKR9-23b)
Enforce precise multi-stage navigation rules and optimize cyclist safety at major signalized intersections with this R9-23b regulatory sign. Explicitly reading "BICYCLE LEFT TURN MUST USE TURN BOX" alongside a bold directional arrow, this high-visibility marker provides a mandatory legal instruction requiring cyclists to utilize a designated two-stage bicycle turn box instead of merging across lanes of vehicular traffic. This keeps bicycle movements highly predictable and significantly reduces potential conflicts with passing motor vehicles.
