Iowa fatal crashes in 1999

FARS records 490 deaths in 428 fatal crashes in Iowa in 1999.

In 1998 it records 449 deaths in 386 fatal crashes.

This site gives no rate for the years before 2000.

Deaths in Iowa rose by 9.1% from 1998 to 1999. In the United States they rose by 0.5%.

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.

Note: this site has no rate for the years before 2000.

Note: FARS records a driver as drinking when police reported alcohol involvement or a test of the driver was positive for alcohol. It is not NHTSA's alcohol-impaired measure. NHTSA's definitions

NHTSA says that its count of drinking drivers is unreliable for 1977, 1981 and 1999 to 2007, because it was derived in a wrong way. This site gives no count for these years.

For the years before 2015 the count is from the FARS element DRUNK_DR. It counts a blood alcohol concentration of .01 g/dL or more. From 2015 the count is from DR_DRINK and counts .001 g/dL or more.
