Objective The aims of this study were: to evaluate a homogeneous sample of truck drivers of dangerous goods (TDDGs) in order to assess the prevalence of obstructive sleep apnea (OSA), and to verify the secondary risk of motor vehicle accidents (MVAs) and near miss accidents (NMAs) in this population. Methods A sample of 283 male TDDGs was evaluated. None of the subjects reported OSA symptoms before screening. Clinical and physical evaluation, Epworth Sleepiness Scale (ESS), and the items on OSA from the Sleep Disorder Score (SDS) questionnaire were used to select subjects with suspicion of OSA. Polysomnography (PSG) was performed to confirm the diagnosis of OSA. The frequency of MVAs and NMAs was assessed at baseline for the whole sample, and also for the drivers with severe OSA after two years of continuous positive airway pressure (CPAP) treatment. Results The mean age of the sample was 42.3 ± 8.3 years. A total of 139 (49.1%) subjects had suspected OSA, and the PSG study confirmed the diagnosis in 35.7%. A significant association between OSA severity and NMAs was observed, and subjects with severe OSA showed a near five-fold increased risk of NMAs (OR = 4.745, 95% CI 1.292–17.424, p = 0.019). After two years of CPAP treatment, the rate of NMAs was comparable with drivers without OSA, showing the efficacy of therapy. Conclusion This study showed an unexpected high prevalence of OSA in TDDGs. Untreated subjects with severe OSA had a significantly increased risk of NMAs. In professional drivers, screening, treatment, and management of OSA are mandatory for reducing road accident risk and improving road safety.
