This study assessed cardiorespiratory fitness (CRF) and 24‐h sleep, sedentary behavior (SB), and physical activity (PA) in Australian truck drivers. Participants ( n  = 37 men) attended clinic sessions for an exercise test to exhaustion to establish CRF and wore an accelerometer (Actigraph GT3X+) to estimate sleep, SB, and PA. Relative to normative values, CRF was “below percentile 25” in 51% of drivers (mean [SD] VO 2peak=30 .1 [7.6] mL.kg‐1.min‐1). Accelerometer data indicated that total vigorous‐intensity (3.5–4.5 min/day) and sustained moderate‐ to vigorous‐intensity PA (>5 min; 0.5–1.6 bouts/day) were limited. The findings show there is a need to design and test PA interventions that can improve poor levels of CRF in truck drivers.
