Deaths in Illinois rose by 1.4% from 1983 to 1984. In the United States they rose by 3.9%.

In 1984, a driver was recorded as drinking in 42.7% of fatal crashes in Illinois and 41.0% 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.
