Commercial Truck Driver Medical Requirements

Protecting the Safety of Others on the Road

The most important safety feature for any commercial driver is the driver themselves. Because truck drivers operate such heavy and dangerous machinery, they are required to abide by federal regulations regarding driver medical requirements; namely, they must undergo a physical examination to prove they are healthy enough to perform their job's duties. Negative consequences await trucking companies that hire unfit drivers.

FMCSA Medical Certification Process

Under the Federal Motor Carrier Safety Administration (FMCSA), truckers are required to undergo the medical certification process to ensure that they are physically qualified to meet the demands of their job. Every driver needs to take a DOT (Department of Transportation) physical exam with an examiner every 24 months.

These licensed medical examiners may include the following:

  • Doctors of Medicine
  • Doctors of Osteopathy
  • Physician Assistants
  • Advanced Practice Nurses
  • Doctors of Chiropractics

In some cases, certification may be valid for less than 24 months if the examiner determines that the driver in question has a condition such as high blood pressure that needs to be monitored more closely.

2012 Update

Since 2012, commercial drivers have been required to provide medical certification status to state driver licensing agencies to obtain a "certified" medical status on their record. This law is only required for interstate non-excepted and intrastate non-excepted commercial drivers. Once a commercial driver's license is revoked, an employer is no longer permitted to allow this driver to operate one of the vehicles. If a driver is found with a revoked driver's license, the driver and the employer will face severe penalties, ranging from termination of job to jail time.

Do Certain Medications Disqualify a Commercial Driver?

If a CMV driver takes any drug that is either a controlled substance or a prescription drug that is being used without a proper prescription, they will be considered unqualified. Approved and non-approved medications are determined considering the possibilities of hazards behind the wheel.

According to the FMCSA, drivers can also be disqualified if they use the following the medications:

  • Methadone
  • Anti-Seizure Medication
  • Drugs Identified in 21 CFR 1308.11 (391.42(b)(12))
  • Habit-Forming Drugs such as Amphetamines

In some cases, there may be exceptions for drivers who have received written proof from a doctor stating that they are safe to operate commercial motor vehicle while taking their medication. In these situations, it will be up to the examiner to determine whether or not to qualify them. Currently, drivers using marijuana cannot become certified, whether it is being used medically or recreationally.

  • How Long Does an 18-Wheeler Lawsuit Take?

Some cases resolve in months, while others take years. The best way to get an estimate for your case is to consult an experienced Texas truck accident lawyer. At Arnold & Itkin, we investigate accidents quickly, determine liability, and prepare every case for trial to secure the best possible outcome as efficiently as possible.

  • How Are 18-Wheeler Accidents Different from Car Accidents?

    Truck accident cases are far more complex than standard car accidents due to the sheer size and weight of 18-wheelers, which cause greater damage and more severe injuries. Unlike car accidents, trucking cases often involve multiple liable parties, including the truck driver, trucking company, cargo loaders, and manufacturers. These cases also require knowledge of federal and state trucking regulations, making it essential to work with a Houston truck accident attorney who has experience handling complex claims and holding powerful trucking companies accountable.

  • How Common Are Fatal Truck Accidents?

    Fatal truck accidents remain a significant concern in the United States. In 2022, 5,936 people lost their lives in crashes involving large trucks, marking a 2% increase from 2021 and a 49% rise over the past decade. Notably, 70% of these fatalities were occupants of other vehicles, 19% were truck occupants, and 11% were non-occupants, such as pedestrians and bicyclists. Texas, in particular, has experienced a high number of such incidents, with 810 deaths resulting from large truck crashes in 2022. This underscores the critical need for stringent safety measures and regulations to protect all road users from the dangers associated with large truck operations.

  • What Is the Statute of Limitations for a Truck Accident Case in Texas?

    In Texas, the statute of limitations for filing a truck accident lawsuit is generally two years from the date of the accident, as outlined in Texas Civil Practice & Remedies Code § 16.003. This applies to personal injury and wrongful death claims, but exceptions exist. If the claim involves a government entity, a notice of claim may be required within six months. If injuries were not immediately apparent, the clock may start from the date of discovery. Additionally, for minors or incapacitated victims, the deadline may be extended. Missing the statute of limitations can bar you from seeking compensation, so it’s critical to act quickly and consult a Texas truck accident lawyer to protect your rights.

  • How Does Failing to Properly Maintain Trucks Lead to Accidents?

    Failing to properly maintain trucks leads to accidents by increasing the risk of mechanical failures that make the vehicle unsafe to operate. Worn brakes can prevent a truck from stopping in time, underinflated or worn tires can lead to blowouts, and faulty steering systems can cause a driver to lose control. Additionally, malfunctioning lights reduce visibility, increasing the likelihood of collisions, especially at night. Neglecting routine inspections and repairs puts both truck drivers and other motorists at serious risk. Federal regulations require trucking companies to conduct regular maintenance, but when they cut corners to save time and money, lives are put in danger.

  • Who Is Liable for a Truck Accident?

    Liability for a truck accident can involve multiple parties, depending on the cause of the crash. The truck driver may be responsible if negligence—such as speeding, distracted driving, or fatigue—played a role. The trucking company can be liable if it failed to follow safety regulations, pressured drivers to exceed legal hours, or neglected vehicle maintenance. Manufacturers may be accountable for defective parts, while maintenance providers could be at fault for improper servicing. Additionally, cargo loaders might bear responsibility if unsecured or overloaded cargo contributed to the accident. Because truck accident liability is often complex, a thorough investigation is essential to identify all responsible parties and pursue full compensation.
