Idaho fatal crashes in 2011

FARS records 167 deaths in 152 fatal crashes in Idaho in 2011.

In 2010 it records 209 deaths in 185 fatal crashes.

In 2011 the rate is 10.5 deaths for each 100,000 residents in Idaho and 10.4 in the United States.

By deaths for each 100,000 residents in 2011, Idaho was number 25 of 51, the 50 states and the District of Columbia.

Deaths in Idaho fell by 20.1% from 2010 to 2011. In the United States they fell by 1.6%.

In 2011, a driver was recorded as drinking in 31.6% of fatal crashes in Idaho and 30.9% in the United States.

To qualify as a FARS case, the crash had to involve a motor vehicle traveling on a trafficway customarily open to the public and must have resulted in the death of a motorist or a non-motorist within 30 days of the crash.

The set of first files, known as the Annual Report File (ARF), is released following the crash year. The ARF is replaced about a year later with a final file, which contains additional cases or updates to cases that had become available after the ARF was released.
