Illinois fatal crashes in 1975
FARS records 2,041 deaths in 1,823 fatal crashes in Illinois in 1975.
This site gives no rate for the years before 2000.
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.

NHTSA says that the alcohol data of the early years, especially 1975 and 1976, must be used with care.
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.
