Here is some helpful information from the Virginia Department of Transporation’s website:
Speed-limit signs are installed on VDOT-maintained roadways following a traffic engineering study.
That study assesses several factors, including:
- Roadway characteristics
- Conflict potential
- Eighty-fifth percentile speed
Once the study is complete, a recommendation is made to the commonwealth transportation commissioner for approval.
To request a study and posting, contact your local VDOT residency.
VDOT can only provide studies for public roads. Public roads are identified by the black and white route number signs at an intersection. Have the route number for the road study available when requesting a study.
