Key points
- Insomnia affects an estimated 27.5% of professional truck drivers -- nearly two to three times the general adult rate.
- In a study of 949 drivers, insomnia was linked to an 82% higher risk of motor vehicle accidents and a 235% higher risk of near-miss accidents, independent of sleep apnea or short sleep duration.
- This is a documented occupational safety issue, not just a personal inconvenience, and screening programs exist specifically because of this data.
Short answer: insomnia affects roughly 1 in 4 professional drivers, and it's a documented, correctable safety issue -- not just an inconvenience. If you drive for a living and can't sleep on your off hours despite being exhausted, you're dealing with something the transportation-safety research has studied specifically and taken seriously, not a personal failure to unwind.
Why is insomnia so much more common among truck drivers?
Several occupational factors compound: irregular and often reversed sleep schedules, sleeping in a truck cab or unfamiliar hotel rooms rather than a stable bedroom, high caffeine intake to manage fatigue (which can itself interfere with sleep onset), extended and sometimes unpredictable hours, and elevated stress tied to deadlines, family separation, and financial pressure. Long-haul driving also frequently overlaps with obstructive sleep apnea risk related to sedentary work and higher rates of overweight/obesity in the profession, which can worsen sleep quality independently of insomnia itself.
What human studies actually show
The most direct evidence comes from a cross-sectional study of 949 truck drivers published in PLoS ONE (Garbarino S, Magnavita N, Guglielmi O, et al. Insomnia is associated with road accidents. Further evidence from a study on truck drivers. PLoS One. 2017;12(10):e0187256. doi:10.1371/journal.pone.0187256.). Insomnia affected 27.5% of the sample. After statistically correcting for the presence of sleep apnea, excessive daytime sleepiness, short sleep duration, and other diseases, insomniac drivers still had an 82% higher risk of motor vehicle accidents (OR 1.82) and more than triple the risk of near-miss accidents (OR 3.35) compared to non-insomniac drivers in the prior 3 years and 6 months, respectively. The researchers specifically recommended routine insomnia screening for commercial drivers as a road safety measure.
A separate Japanese study of truck drivers found a chronic insomnia prevalence of 13.3%, still meaningfully higher than the roughly 3-7% typically seen in general population studies, and identified caffeine intake before sleep and family, relationship, or health-related stress as specific correlates within this occupational group.
The honest counterweight: prevalence estimates for sleep problems in truck drivers vary substantially across studies -- from about 13% to over 27% for insomnia specifically, and 20-50%+ for sleep apnea depending on methodology and country. This range reflects real differences in screening tools, sample selection, and regional driving-hour regulations, so no single number should be treated as the definitive rate; the consistent finding across studies is that rates are elevated compared to the general working population, not the exact size of the elevation.
What this doesn't mean
Feeling exhausted but unable to sleep during off-hours doesn't necessarily mean you have obstructive sleep apnea, though the two frequently co-occur in this population and it's worth ruling out given how treatable OSA is once diagnosed. It also doesn't mean the fix is simply "try harder to relax" -- the occupational and circadian factors involved are structural, not just psychological, which is part of why night-shift and irregular-schedule sleep strategies are relevant background even for drivers who aren't technically on a fixed night shift.
What actually helps
Given the safety stakes, screening is the first step: many fleet safety programs now include sleep disorder screening specifically because of data like the studies above. Beyond that, protecting a consistent sleep window even across irregular routes, limiting caffeine intake in the 6-8 hours before your planned sleep period, and treating any diagnosed sleep apnea are the interventions with the strongest safety evidence behind them. Bringing new or worsening insomnia to a doctor -- rather than self-managing with over-the-counter aids alone -- is particularly important in a safety-sensitive occupation.
Frequently asked questions
Is insomnia actually more dangerous for drivers than just being tired?
The research suggests insomnia carries an independent accident risk beyond what's explained by sleep apnea, short sleep duration, or general daytime sleepiness alone -- meaning it's not just a proxy for being tired, it appears to have its own measurable safety impact.
Does caffeine before a shift make insomnia during off-hours worse?
Research in this specific population has flagged caffeine intake close to sleep as a correlate of insomnia among drivers, which lines up with the broader pharmacology of caffeine's long half-life in slower metabolizers.
Should truck drivers be screened for sleep apnea even without insomnia symptoms?
Given how common undiagnosed sleep apnea is in this occupation -- some studies estimate over half of drivers may be at risk -- and its independent link to accidents, screening programs generally recommend evaluation regardless of whether insomnia is also present.
Are there legal/regulatory sleep disorder screening requirements for commercial drivers?
Requirements vary by country and carrier; in the U.S., the Federal Motor Carrier Safety Administration has issued guidance on evaluating drivers for sleep apnea specifically, though requirements and enforcement differ across companies and jurisdictions.

Why we formulated Sleep+ Restore
Sleep+ Restore combines 10 mg of melatonin with a 905 mg proprietary blend -- including L-tryptophan, L-theanine, chamomile, passionflower, ashwagandha, GABA, 5-HTP, and St. John's Wort -- designed around ingredients studied for their roles in sleep onset and relaxation.
Every order is backed by a 60-day money-back guarantee -- long enough to actually evaluate it the way the research says you should.
Given what's discussed above, this is worth mentioning to your doctor or pharmacist before adding any new sleep supplement -- particularly because Sleep+ Restore contains St. John's Wort and 5-HTP, both of which can interact with certain prescription medications.

Insomnia in truck drivers isn't a minor inconvenience -- it's a documented, independently measured safety risk with a real evidence base behind screening and intervention. If this describes your situation, it's worth treating as seriously as the research does: bring it to a doctor, ask about sleep apnea screening, and don't assume it's just part of the job.
What about drivers who work irregular but non-commercial schedules?
While the strongest data here comes specifically from professional truck drivers, the underlying mechanisms -- irregular schedules, caffeine reliance, unfamiliar sleep environments, and elevated occupational stress -- generalize reasonably well to other safety-sensitive, schedule-irregular jobs such as rideshare driving, delivery driving, and other transportation roles, even though those specific populations haven't been studied in as much depth. The core takeaway (screen for insomnia and sleep apnea rather than assuming fatigue is just an unavoidable cost of the job) applies broadly across these roles.
For drivers whose schedule specifically involves working through the night, our guide on sleeping during the day for night shift work covers additional circadian strategies relevant to reversed schedules.
What role does obstructive sleep apnea play alongside insomnia in this population?
Because obstructive sleep apnea and insomnia frequently co-occur in truck drivers -- one study found insomniac drivers had a significantly higher prevalence of OSA than non-insomniac drivers, alongside higher rates of cardiovascular disease, diabetes, and depression -- screening programs increasingly test for both conditions together rather than treating them as separate issues. This matters practically because treating OSA alone, without addressing a coexisting insomnia pattern, often leaves a driver still struggling with sleep initiation or maintenance even after a CPAP machine resolves the breathing component.
