Objective This study aims to quantify the crash risk for truck drivers with multiple comorbid medical conditions, after adjusting for confounders. Methods This retrospective cohort of 38,184 drivers evaluated concomitant medical conditions and subsequent crash data between 1/1/2005–10/31/2012. Hazard ratios (HRs) and 95% confidence intervals (95% CI) were calculated for any cause and preventable crashes of varying severity. Results Drivers with three or more medical conditions had significantly increased risk of preventable Department of Transportation (DOT) reportable crashes (HR=2.53, 95% CI=1.65–3.88) and preventable crashes with injuries (HR=2.23, 95% CI=1.09–5.31) after adjustment for covariates. Similarly, adjusted HRs were 2.55 (95% CI=1.37–4.73) for any cause DOT-reportable crashes and 3.21 (95% CI=1.18–8.75) for any cause crashes with injuries. Conclusions Having three concomitant medical conditions may be a statistically significant risk factor for preventable and any cause DOT-reportable crashes and crashes with injuries.
