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.
