The NHTSA Crash data Application Programming Interface (API) provides various ways to get crash data collected by DOT NHTSA’s Fatality Analysis Reporting System (FARS) program. The APIs are primarily targeted for developers, programmers or researchers interested in obtaining Crash statistics on Fatal Motor Vehicle Crashes. The API supports multiple data output formats, namely, XML, CSV/XLSX, JSV and JSON. FARS data starting from 2010 onwards is made available through this website. There are different APIs provided to make it easier to query specific data.

For non-developers that would like to query FARS data, please visit www-fars.nhtsa.dot.gov/querytool/
