Before a driver can operate a commercial motor vehicle (CMV), they must undergo a DOT medical examination by a certified medical examiner. The examination is required by the U.S. Department of Transportation (DOT) and (among other things) screens for disqualifying mental conditions that could put the safety of the driver and the public at risk.
In this blog, we explore what DOT disqualifying mental conditions are, why they matter, how employees and employers can navigate them, and legal and ethical considerations for DOT mental health standards.

Commercial trucking is a critical part of the U.S. economy, but it is also a risky occupation for both drivers and the public. According to the Federal Motor Vehicle Carrier Safety Administration (FMCSA), of all occupations in the U.S., trucking industry workers experience the third highest fatality rate, accounting for 12% of all deaths. About two-thirds of these fatalities involve highway crashes.
Many factors contribute to these incidents, including mental health. The ability to concentrate, coordinate, make quick decisions, and have a rational, stable personality are essential to safe driving. Mental, behavioral, or psychiatric conditions which interfere with these traits can impair driving abilities.
To reduce the incidents of road traffic accidents and satisfy DOT mental health requirements, a truck driver must be screened in alignment with DOT standards and guidelines before they can be certified as fit for duty. If found to have a disqualifying mental health condition, a driver can be removed from duty or be denied a commercial driver’s license (CDL).
DOT mental health standards are set forth and enforced by the FMCSA. To screen for any disqualifying mental conditions, truck drivers must undergo a rigorous pre-employment medical exam and further screening every two years. These exams assess an individual’s physical and mental ability to safely operate a CMV.
An individual who has a DOT-disqualifying mental condition may still be able to drive a truck, thanks to certain FMCSA exemptions.
For example, if an individual states on their medical questionnaire that they have been diagnosed with a schizoaffective disorder, the medical examiner will ask further questions to establish if the individual is on a treatment plan, how effective it has been, and if the medication has any side effects.
Similarly, an individual who takes anti-depressants may still pass the DOT medical exam if a letter is obtained from their physician stating that the condition is managed, and any medication would not impair safe driving.
However, regardless of the presenting condition, it is up to the medical examiner whether to certify that individual.
Commercial truck driving is a skilled profession and mental fitness is a key part of occupational safety in the transportation industry.
Periodic mental health screening keeps the nation’s roads safer by ensuring that drivers can handle the mental demands and emotional stressors of operating a commercial vehicle.
Indeed, FMCSA studies suggest that traits such as aggression, hostility, impulsivity, disregard for laws (i.e., attitude toward traffic law violations), and various psychological symptoms are associated with an increase in crash risk.
For instance, depression is known to impair cognitive function and may be associated with suicidal ideation or suicide attempts, even homicidal thoughts. Bipolar disorders are also associated with poor judgment and impulsivity.
Even when treated to full remission, individuals with behavioral health disorders can demonstrate residual disturbances or short-term memory, concentration, and mental processing speed.
Employers and employees in the transportation industry should understand DOT disqualifying conditions – both physical and mental. Without knowing the conditions, drivers can risk injury or death – and employers could face legal or regulatory consequences.
DOT disqualifying medical conditions for CMV drivers include:
A DOT physical exam will screen for disqualifying medical conditions. The exam is conducted by a FMCSA-certified medical professional. During the assessment, the professional will evaluate an employee’s:
DOT disqualifying mental conditions include:
In addition to disqualification based on DOT-defined mental conditions, drivers cannot use disqualifying drugs, such as anti-depressants and anti-psychotics that have effects and/or side effects that may interfere with the ability to drive a CMV safely.
Mental health conditions are screened for during a DOT physical exam. Prior to the exam, the applicant or incumbent driver will be asked to complete a medical history questionnaire.
The mere diagnosis of a particular psychological disorder does not automatically preclude medical certification. Typically, however, the more serious the diagnosis, the more likely it is that the driver may not be physically qualified.
With the rising demand for commercial goods and the increasing need to expedite their deliveries, truck drivers are facing a growing mental burden. Additionally, the current driver shortage adds further stress to their already demanding job.
Depression and anxiety disorder are the most commonplace mental health conditions in the transport industry. Unfortunately, they often lead to substance abuse disorders.
Depression is the top mental health diagnosis among truck drivers. According to HealthyTruck.org, 13.6% of truck drivers suffer some form of depression, compared to 1.5% of the general population.
Depression and anxiety can be caused by several factors, including loneliness, lack of sleep, financial worries, work pressures, and more. Additionally, men dominate the transport industry, and they are less likely to seek medical assistance or social support.
Left untreated, mental health issues can impact work performance and lead to disqualification. A study by the National Institutes for Health (NIH) found that depression and anxiety increase the chance of a driving accident by 3.6 times in truck drivers.
Individuals with mental health disorders have a high propensity to turn to drugs and alcohol to cope with their symptoms.
According to American Addiction Centers, 27.6% of truck drivers admitted consuming drugs, mainly amphetamines (21.3%) and cocaine (2.7%). Findings suggest they use these stimulants to stay awake or increase their productivity.
If an employee tests positive for substance abuse disorders during a pre-employment/employment medical exam or random screening, DOT regulations disqualify them.
Below are steps that truck drivers and employers in the transportation industry can take to navigate DOT mental health requirements.
The best way to avoid disqualification under DOT mental health regulations is to practice mental health management. Vital actions include staying connected with family and loved ones when on the road, getting good quality sleep, and finding a way to relax.
Drivers should also recognize the symptoms of mental health struggles such as feeling tense, headaches, insomnia, mood swings, stomach problems, or a loss of interest in enjoyable activities. Many trucking companies offer employee wellness resources that can help drivers discuss and work through any concerns they may have.
From a health and wellness perspective, being a truck driver is one of the hardest jobs in the world. To support their employees, employers should invest in wellness programs that incorporate mental health resources and workplace support.
In addition to helping truck drivers comply with DOT mental health standards and stay on the job, a commitment to a healthy workforce ensures workers feel valued, attracts new talent, and decreases healthcare and worker’s compensation costs.
Although trucking companies must comply with DOT mental health standards by screening and potentially disqualifying employees in safety-sensitive positions, there are legal and ethical considerations to be aware of.
For example, prior to any disqualification, the Americans with Disabilities Act (ADA) requires that employers consider an individual’s specific health condition and the likelihood of potential threat or harm associated with that condition.
Furthermore, under the ADA, if the driver’s condition does represent a safety risk, then employers must make reasonable accommodations for that mental limitation. For example, unmanaged depression can lead to rash decision-making or a distracted state – a worrisome situation for any truck driver. But many people with depression can manage their disorder and not represent a direct threat. This determination can only be made by a DOT-certified medical examiner.
Businesses also have an ethical responsibility to maintain the privacy and confidentiality of employees’ mental health challenges. Employers should establish protocols and policies for the provision of confidential mental health resources and support and ensure secure record-keeping and communication channels.
Truck driving plays a crucial role in the national economy; however, it is an inherently taxing and demanding occupation. The extended hours spent on the road can exact a toll on drivers. The isolation and intense concentration involved can contribute to mental health issues such as depression and anxiety and may even give rise to substance abuse concerns.
Despite the impact that mental health can have on overall driver performance – and public safety – many truck drivers lack access to much-needed support and resources. The consequences can be costly. An individual with DOT-disqualifying mental conditions can miss out on employment opportunities, lose their commercial driver’s license, and suffer financial hardship.
There are also consequences for employers. A failure to maintain mental health standards for DOT employees can result in absenteeism, lost productivity, rising healthcare and worker’s compensation costs – and potential liabilities from any related road traffic accidents or fatalities. Failing to include mental health screening as part of DOT medical exams can also result in penalties or fines from the FMCSA.
