I-20 in South Carolina recorded 27 deaths in large-truck crashes during 2020 to 2024, compared with 89 deaths across all crashes assigned to the route. Large-truck crash deaths represented 30.3% of all route deaths. The segment recorded 24 fatal large-truck crashes during that period. These truck accident deaths include everyone killed in the qualifying crashes, rather than only people occupying large trucks. The death count and fatal-crash count measure different things.[1][2][3][4][5][6][7]

For this I-20 South Carolina summary, 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 I-20 uses the crash-level route fields: ROUTE=1 and a parseable I-route number in TWAY_ID, the recorded trafficway identifier. Those fields identify route signing and crash location; they do not describe the highway's full geographic extent.[1][2][3][4][5][6][7]

About these figures

For I-20 in South Carolina, FARS supplies fatal-only truck accident data; nonfatal crashes and injuries are excluded. State and county counts follow crash locations, not residence. Crash-level ROUTE and TWAY_ID fields assign the route; they describe signing and location, not full highway coverage. Large-truck involvement does not establish fault.[8][6][7]

The 2020 to 2023 figures use FARS Final Files. The 2024 Annual Report File remains revisable when NHTSA supplies the Final File. FARS includes qualifying traffic crashes when an occupant or nonoccupant dies within 30 days. A reader searching for a truck accident lawyer should read these I-20 South Carolina figures as location-based death and fatal-crash counts. The packet supplies no population or mileage rates.[8][6][7]
