Summary
DescriptionDiagram of signalized crosswalks at four-way intersection, pedestrian signals not specified.svg
English: An idealized diagram of a four-way signalized intersection with an unmarked crosswalk on one side and a marked crosswalk on the opposite side. An icon on either end of both crosswalks indicates that it is unknown whether the crosswalk has dedicated pedestrian signals. In the United States, a pedestrian must obey the vehicular signals in the absence of pedestrian signals. Colors and signals are based on the diagrams in the 2009 MUTCD. [1][2] Question marks are set in Roadgeek 2014 Series E.
