In 1985 it records 474 deaths in 416 fatal crashes.

This site gives no rate for the years before 2000.

Deaths in Iowa fell by 7.0% from 1985 to 1986. In the United States they rose by 5.2%.

In 1986, a driver was recorded as drinking in 43.6% of fatal crashes in Iowa and 42.5% 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.
