Road debris

Road debris, a form of road hazard, is debris that accumulates on or off a road. Road debris includes substances, materials, and objects that are foreign to the normal roadway environment. Debris may be produced by vehicular or non-vehicular sources, although in all cases it is considered litter, a form of solid waste.^[1] Debris may tend to collect in areas where vehicles do not drive, such as on the edges (shoulder), around traffic islands, and junctions.

Road spray^[2] or tire kickup is road debris (usually liquid water) that has been kicked up, pushed out, or sprayed out from, a tire. In 2004, a AAA Foundation for Traffic Safety study revealed that vehicle-related road debris caused 25,000 accidents and nearly 100 deaths a year.
