Generalized ordered logit models were estimated separately for the three lighting conditions, and likelihood-ratio tests were used to justify the separate model structure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The generalized ordered logit models showed better relative in-sample fit than the ordered logit models, with pseudo R-squared values of 0.19, 0.24, and 0.44 for the daylight, dark-not-lighted, and dark-lighted subsets, respectively. Driver-behavior factors \u2013 including fatigued driving, careless or inattentive driving, drug or alcohol involvement, and failure to keep in the proper lane \u2013 were associated with increased probabilities of major truck-occupant injury. Roadway-context variables, such as roadway grade, two-lane segments, adverse weather, and segments with higher posted speed limits, showed condition-specific associations with injury severity, particularly under nighttime conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The findings suggest that rural lighting improvement and nighttime truck safety management should be prioritized for high-risk roadway and driver-behavior scenarios.
