"The nine bicyclists, who were part of a private club known as the Chain Gang, were on a 28.5-mile trip when a pickup truck hit them, the NTSB says. The pickup, which was traveling in the same direction as the bikers, left the roadway for unknown reasons and drove onto the paved, four-foot-wide shoulder where the bikers were pedaling, striking the entire group from the rear.
The pickup’s driver, Charles Pickett Jr., 50, who allegedly popped muscle relaxants and pain pills before getting behind the wheel, is awaiting trial on charges that include second-degree murder and operating a vehicle while intoxicated, local media reports say.
...But the NTSB’s interest in a bicycle accident is unusual. The agency decided that the crash was worth investigating not only because of its severity but because of the growing popularity of bicycling as an alternative to vehicles.
“We last looked at cycling in the early 1970s,” NTSB spokesman Eric Weiss said in an email Tuesday. “We’re looking at the Kalamazoo crash as part of an effort to examine the future roadway, where cars and trucks increasingly share the road with cyclists and pedestrians.”
More than 900 bicyclists were killed, and approximately 494,000 were taken to emergency rooms for injuries in 2013, according to the Centers for Disease Control and Prevention. MLive.com, in an analysis of Michigan State Police accident data, found that the state’s bicycle fatalities had risen 57 percent compared with the previous year, even before the Kalamazoo fatalities. The National Highway Transportation Administration (NHTSA) says motor vehicle crashes significantly underestimate the number of injured pedestrians and bicyclists."
