I-84 in Connecticut recorded 24 deaths in large-truck crashes during 2020 to 2024, alongside 82 deaths from all fatal crashes assigned to the route. Large-truck crash deaths represented 29.3% of all route deaths. The segment had 19 fatal large-truck crashes during that period. These truck accident death counts include everyone killed in the qualifying crashes, rather than only people occupying large trucks, and describe the Connecticut segment's recorded crash locations.[1][2][3][4][5][6][7]

For I-84 in Connecticut, a truck accident means a fatal crash involving at least one medium or heavy truck with a gross vehicle weight rating greater than 10,000 pounds, excluding buses and motor homes. Assignment to this corridor uses the crash-level route fields: ROUTE=1 and a parseable I-route number in TWAY_ID. Those recorded fields identify route signing and crash location; they do not describe the highway's full geographic extent.[1][2][3][4][5][6][7]

The other-state rows supply selected segment comparisons, not the complete route-wide breakdown. Their counts should not replace the separately supplied total of 102.

They are not traffic-adjusted risk rankings and do not establish relative truck accident risk per trip or mile.[1][2][3][4][5][6]

About these figures

For I-84 in Connecticut, FARS supplies fatal-only truck accident counts; nonfatal crashes and injuries are excluded. Qualifying traffic crashes involve a death within 30 days. State and county fields place deaths at the crash location, rather than the person's residence. Crash-level ROUTE and TWAY_ID fields assign the corridor, describing recorded route signing rather than the highway's full geographic extent.[8][6][7]

Large-truck involvement does not establish fault. Readers using the phrase "truck accident lawyer" should keep these counts grouped by crash location. Connecticut's I-84 figures use FARS Final Files for 2020 to 2023 and the Annual Report File for 2024. NHTSA can revise the 2024 figures when it replaces that file with the Final File.[8][6][7]
