Va. Code § 33.2-253
The Commissioner of Highways shall establish a highway safety corridor program under which a portion of highways in the primary state highway system and Interstate System may be designated by the Commissioner of Highways as highway safety corridors to address highway safety problems through law enforcement, education, and safety enhancements. In consultation with the Department of Motor Vehicles and the Superintendent of State Police, the Commissioner of Highways shall establish criteria for the designation and evaluation of highway safety corridors, including a review of crash data, accident reports, type and volume of vehicle traffic, and engineering and traffic studies. The Commissioner of Highways shall hold a public hearing prior to the adoption of the criteria to be used for designating a highway safety corridor. The Commissioner of Highways shall hold a minimum of one public hearing before designating any specific highway corridor as a highway safety corridor. The public hearing or hearings for a specific corridor shall be held at least 30 days prior to the designation at a location as close to the proposed corridor as practical.
The Department of Transportation shall erect signs that designate highway safety corridors and the penalties for violations committed within the designated corridors.
