Crashes Involving Road Debris – Scope of the Problem and Mitigation

Release Date: August 24, 2016

Results from a study by the AAA Foundation for Traffic Safety suggest that road debris was a factor in an estimated average of 50,658 police-reported crashes, which resulted in 9,805 injuries and 125 deaths annually in the United States over the years 2011-2014. Debris-related crashes were more likely than non-debris-related crashes to result in property-damage only; debris-related crashes were roughly half as likely as non-debris-related crashes to result in injury or death.

Compared with crashes that did not involve debris, debris-related crashes were approximately four times as likely to occur on interstate highways. High speeds can increase the risk of cargo falling from vehicles; increase the chance of wheels, tires, or other parts separating from vehicles; and decrease the time a driver has to react to hazards created by airborne debris or debris lying on the road.

For the study, debris-related crashes were defined as crashes in which a vehicle struck or was struck by an object that fell or became detached from another vehicle, struck a non-fixed object on the roadway, or crashed after swerving to avoid an object on the roadway. Crashes that involved live animals, trees falling onto vehicles, debris associated with a recent previous crash, construction-related debris in work zones, or debris outside of the travel lane were not counted as debris-related crashes.

To avoid being involved in a debris-related crash, focus on the following:

Additionally, it is every driver’s responsibility to assure that the contents of their vehicle are properly secured, intermittently check the securement devices during a trip, and properly maintain the vehicle. Should something dislodge from a vehicle, the driver needs to protect the scene where possible, move the item(s) off the roadway when safe to do so, and notify law enforcement about hazards to other drivers.
