About these figures

For I-5 in Washington, FARS counts fatal traffic crashes involving a motor vehicle on a trafficway customarily open to the public, with a death within 30 days. Nonfatal crashes and injuries are excluded. State and county fields locate the crash, not the person's residence. Crash-level ROUTE and TWAY_ID fields assign this corridor through route signing and a parseable I-route number, without mapping its full extent.^[8][6][7]

Large-truck involvement does not establish fault. Readers searching for a truck accident lawyer should distinguish death counts from fatal-crash counts. Washington's I-5 truck accident figures use FARS Final Files for 2020 to 2023; the 2024 Annual Report File remains revisable when NHTSA replaces it with the Final File.^[8][6][7]
