Road hazards and the threat they present to traffic safety is discussed on the “McHenry County Road Hazards” page. As seen on that page, road hazards can take many forms. Among the most dangerous road hazards are those objects that hit vehicles as they drive down the expressway or other roadway. These objects can include tires and wheels which have detached (often called “wheel separations”) from other vehicles. One such Chicago-area accident that involved a wheel that had detached off of a SUV and fatally struck a driver in a car as the driver was traveling on the Bishop Ford Freeway.
Other types of road hazards can include high standing water on the roadway. Depending on the depth of the water and other characteristics, this standing water can cause hydroplaning or other adverse impacts on vehicle handling, which can lead to a loss of vehicle control.
Another type of road hazard is large potholes or other types of substantial road deformities which, if hit by a vehicle, can cause the driver to lose control.
One of the reasons that road hazards are potentially dangerous is that they often are unexpected; as well, they can suddenly appear and as such may leave the motorist with little reaction time to successfully react to the hazard.
As well, if the motorist is driving at night or other situations with limited visibility, these road hazards can be especially problematical.
On August 30, 2018 NBC Chicago aired a video segment titled “More Than 9,000 Crashes on Illinois Roads Caused By Debris.” The segment discusses one type of road hazard, debris that is sitting on the roadway. If hit or run over by a vehicle, such debris can cause a range of adverse effects, including a loss of control and/or a crash. As seen in the segment, many people have been injured and some have been killed due to road debris.
An excerpt from the article:
Seventeen people have been killed in crashes caused by debris on Illinois roadways, according to the Illinois Department of Transportation’s most recent data.
From 2012 to 2016, more than 9,000 accidents have resulted in more than 1,500 people injured.
As seen in the segment, there is a wide range of items that IDOT has found on the roadway, including kitchen sinks, grills, and mattresses.
