Motorcycle deaths unaccountably plunge after long rise Washington Post
The report by the Governors Highway Safety Association found that fatal crashes declined nearly 16 percent in the first nine months of 2009, compared with the same period the year before.
There was no ready explanation for the drop, a year after the 5,290 motorcycle fatalities set a record. The speculation included that the economy was keeping motorcyclists off the road, that a 42 percent drop in new motorcycle sales last year resulted in fewer novice riders and that publicity about deaths had heightened the awareness of both motorcyclists and motorists.
The number of fatalities dropped 38 percent in the District , by 26 percent in Maryland and by 13 percent in Virginia , the report said.
"It's good news that fatalities are decreasing, but I really don't have a clue as to why," said Samir Ahmed, an Oklahoma State University expert who is leading a four-year, $3 million research project on the cause of motorcycle accidents. "I really don't see anything that would cause that, unless people are just not riding."
