The data available actually goes back to 1982 and now runs to 2020
Correction

NHTSA’s FARS data are available from 1975, not 1982. Official FARS documentation says the system became operational in 1975 and raw data can be downloaded from 1975 to the present.

Full reasoning

This sentence understates the historical coverage of the Fatality Analysis Reporting System (FARS). NHTSA’s own documentation says FARS became operational in 1975 and that users can download all FARS data from 1975 to present. That means 1982 is not the earliest year the data are available.

It’s possible the author chose to analyze only 1982–2020 for methodological or coding reasons, but the sentence as written says the available data only go back to 1982. NHTSA’s official documentation contradicts that: earlier FARS data exist.
