Note below, where only a handful of Virginia localities are given authority to put up "Yield to Pedestrians" signs. This is one of the things I like about being a "Dillon Rule" state - localities can't even blow their noses without specific authorization to do so.
Va. Code § 46.2-924. Drivers to stop for pedestrians; installation of certain signs; penalty.
A. The driver of any vehicle on a highway shall yield the right-of-way to any pedestrian crossing such highway:
1. At any clearly marked crosswalk, whether at mid-block or at the end of any block;
2. At any regular pedestrian crossing included in the prolongation of the lateral boundary lines of the adjacent sidewalk at the end of a block;
3. At any intersection when the driver is approaching on a highway or street where the legal maximum speed does not exceed 35 miles per hour.
B. Notwithstanding the provisions of subsection A of this section, at intersections or crosswalks where the movement of traffic is being regulated by law-enforcement officers or traffic control devices, the driver shall yield according to the direction of the law-enforcement officer or device.
No pedestrian shall enter or cross an intersection in disregard of approaching traffic.
The drivers of vehicles entering, crossing, or turning at intersections shall change their course, slow down, or stop if necessary to permit pedestrians to cross such intersections safely and expeditiously.
Pedestrians crossing highways at intersections shall at all times have the right-of-way over vehicles making turns into the highways being crossed by the pedestrians.
C. The governing body of Arlington County, Fairfax County, the City of Fairfax, the County of Loudoun and any town therein, and the City of Alexandria, may by ordinance provide for the installation and maintenance of highway signs at marked crosswalks specifically requiring operators of motor vehicles, at the locations where such signs are installed, to yield the right-of-way to pedestrians crossing or attempting to cross the highway. Any operator of a motor vehicle who fails at such locations to yield the right-of-way to pedestrians as required by such signs shall be guilty of a traffic infraction punishable by a fine of no less than $100 or more than $500. The Commonwealth Transportation Board shall develop criteria for the design, location, and installation of such signs. The provisions of this section shall not apply to any limited access highway.
