NACTO: Many patterns

•  Section 9C.07 Shared Lane Marking does not appear to prohibit use within intersection. However, the space within an intersection is not typically referred to as a “lane”.

•  Section 3B.08 Extensions Through Intersections or Interchange •  Single solid or dotted extension line per lane •  Same color as the line it extends

•  Figure 9C-1 Examples of Intersections Pavement markings •  Shows a single dotted white line extending a left turn bike lane

onto a cross street

Two-Stage Turn Queue Box NACTO Urban Bikeway Design Guide: •  Improves bicyclist ability to safely and

comfortably make left turns. •  Provides a formal queuing space for bicyclists

making a two-stage turn. •  Reduces turning conflicts between bicyclists

and motor vehicles. •  Prevents conflicts arising from bicyclists

queuing in a bike lane or crosswalk.
