Commercial Driver's License Requirements

It Takes a Special License to Drive Commercial Vehicles

Commercial trucks require specialized training in order to operate them safely. However, prior to 1986, there were few rules regarding licensing for those who drove large trucks, which is why the Commercial Motor Vehicle Safety Act was signed into law (see more about this below). Currently, to register with the Federal Motor Carrier Safety Administration (FMCSA), the first step for a driver is to find their Department of Transportation (DOT) Number and Operating Authority. An individual who hopes to become a commercial driver will need to compile all of the necessary forms, submit them to the FMCSA, begin a safety assurance program, and then obtain the DOT registration. Some commercial drivers may even need to possess medical certification requirements.

CDL Classes & Endorsements

There are three major types of licenses for commercial drivers along with many different endorsements.

The three major classes of federal commercial drivers' licenses are as follows:

  • Class A are for those driving trucks weighing over 26,000 lbs. or towing a vehicle at least 10,000 lbs.
  • Class B are for those drivers who will be driving vehicles that weigh the same as for Class A licenses (over 26,000 lbs.) but have a towing capacity that cannot exceed 10,000 lbs.
  • Class C are for those who do not fit into either category, such as vehicles designed for the transportation of 16 or more passengers or drivers who are transporting hazardous material.

Endorsements are classified by letters. Drivers that possess these letters on their commercial licenses signify that they are qualified to carry out the following functions.

  • "T" is for drivers who've completed a knowledge-based test to transport double or triple trailers
  • "P" is for those who have passed knowledge and skills tests to transport passengers
  • "N" is for those who have passed a knowledge test to drive a tanker vehicle
  • "H" stands for hazardous material, which requires a knowledge test only
  • "X" is an endorsement for those who drive tank vehicles that carry hazardous materials
  • "S" is for those who have passed knowledge and skills test to become school bus drivers

Commercial Motor Vehicle Safety Act 

One provision of the Commercial Motor Vehicle Safety Act is that each state must develop its own standards for trucking companies, as long as those standards comply with federal standards. This is important when it comes to the formulation of knowledge and skills tests. Knowledge tests require that drivers get at least 80% of the answers correct while the skills test requires the successful completion of all the required skills.

Unfortunately, this is where some drivers try to cheat the system. Licensing fraud has become a bit of a phenomenon in the trucking world recently. Those who have their licenses revoked for some reason may attempt to fraudulently regain their licenses. The Act clearly states that it is illegal for a driver to possess multiple CDLs. Some drivers may even try to manipulate the knowledge and skills tests so that they can pass. All of these practices constitute negligence both on behalf of the driver and the company for failing to notice the problem.

  • What Should I Do After a Texas 18-Wheeler Accident?

Collect the other driver’s information and witness statements. Save all medical records related to your injuries. Get a repair estimate for your vehicle.

  • 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.
