Va. Code § 10.1-1424
No vehicle shall be driven or moved on any highway unless the vehicle is constructed or loaded to prevent any of its load from dropping, sifting, leaking or otherwise escaping therefrom. However, sand or any substance for increasing traction during times of snow and ice may be dropped for the purpose of securing traction, or water or other substances may be sprinkled on a roadway in cleaning or maintaining the roadway by the Commonwealth or local government agency having that responsibility. Any person operating a vehicle from which any glass or objects have fallen or escaped which could constitute an obstruction or damage a vehicle or otherwise endanger travel upon a public highway shall immediately cause the highway to be cleaned of all glass or objects and shall pay any costs therefor. Violation of this section shall constitute a Class 1 misdemeanor.
