Fit the CDL Requirements

What Is a CDL?

A CDL is a Commercial Driver’s License and is a requirement to operate certain commercial motor vehicles. If you were the kid playing with toy trucks and now you want to make that into an real career, the CDL is what you need. 

To drive any vehicle that falls in the following list, you need to get a Commercial Driver’s License and fit the CDL requirements:

  • A gross combination weight rating (GCWR) of 26,001 lbs. or more, to include a towed vehicle that is heavier than 10,000 lbs. (tractor-trailers, flatbeds, and tankers)
    Specific freight requires specific endorsements.
  • A single vehicle with a gross vehicle weight rating (GVWR) of 26,001 lbs. or heavier and/or any vehicle as described above that is towing another vehicle weighing up to 10,000 lbs. (delivery box trucks, straight trucks, and large buses)
  • At least 16 passengers (including you the driver) or Hazardous material (HAZMAT) as laid out by federal guidelines

There are also vehicles that require specific endorsements to drive.

These endorsements, added onto your CDL, let you drive vehicles containing hazardous materials or a school bus.

If you have a specific driving job that you’ve been dreaming about, be sure to take the time to research what license and endorsements you need.

What Are the CDL Requirements?

Before you can take a test and get your Commercial Driver’s License, you must first make sure you fit all of the prerequisites. Truck driving is subject to tons of regulation to keep the roads safe for both truckers and the four-wheelers that share the pavement. These CDL requirements may seem like a pain, but an 80,000 pound truck can pose a lot of danger if it’s not handled correctly.

Some regulations vary by state, but there are basic CDL requirements mandated by the federal government.  In order to get your CDL, you must be at least 21 years old to drive interstate and have no disqualifying felonies. Your driving record will be checked, back at least 10 years.

Most schools and companies also want at least one full year of clean driving with a regular license, so you probably won’t be able to get a CDL if you don’t currently have a driver’s license. 

As a truck driver, you need to have a firm grasp of English, both written and spoken. It’s essential that you can read road signs and communicate with the general public. There aren’t federal requirements for education level, but most companies want a high school diploma or equivalent before they hire you.

You also need to be medically qualified according to the Department of Transportation. This includes:

  • Vision: You must have at least 20/40 vision and able to see color.
  • Hearing: You must be able to hear a forced whisper from at least five feet away, or take an audiometric test which shows no hearing loss greater than 40 decibels at 500 Hz, 1,000 Hz, and 2,000 Hz. Hearing aids are allowed, but you will be required to wear them at all times while driving.
  • Blood Pressure: The maximum allowable blood pressure is 160/100. It’s acceptable to use medication to lower your blood pressure.
  • Diabetes: Diabetics are not permitted to drive trucks if the illness is controlled through insulin injections, but they are permitted if it’s controlled through diet and/or medication. Maximum blood sugar is 200.
  • Cardiovascular issues: Drivers must submit to a stress test and provide a doctor’s note that you can drive a commercial motor vehicle with no restrictions.

Once you pass the DOT physical, you’ll need to carry the medical certificate/physical card with you. Your DOT medical card is valid for two years if you pass all of the standards.

Lastly, effective as of May 10, 2017, you need to provide proof of U.S. citizenship/lawful permanent residency/legal presence as well as proof of residency (domicile).

CDL Disqualifications

There are a few factors that can disqualify you from getting your CDL or prohibit you from using your CDL for at least one year (first offense), if you already have it.

  • Driving a commercial motor vehicle with a BAC of .04 or over. If you are found to have a BAC over zero but under .04, you will be restricted from driving for 24 hours.
  • Driving a commercial motor vehicle OR your personal vehicle under the influence of alcohol or a controlled substance.
  • Refusing breath or blood alcohol testing in your commercial motor vehicle OR personal vehicle.
  • Leaving the scene of an accident.
  • Committing a felony involving the use of a motor vehicle
  • Driving a commercial motor vehicle with a suspended, revoked, cancelled, or disqualified license.
  • Causing a fatality through negligence while operating a commercial motor vehicle.
  • Driving a commercial motor vehicle while in possession of a controlled substance.

Basically, don’t do any of this stuff. A second offense or using a commercial motor vehicle to commit a felony causes a loss of your CDL for life.

There are even more serious consequences if you are driving a commercial motor vehicle with hazardous materials. Truck driving is a challenging and demanding job so be safe, be responsible, and be smart.

Next Steps

Those who meet the above CDL requirements will allowed to drive a truck for a living. (NOTE: If you’re unsure that you fit the medical requirements, skip ahead to Step 5 in order to take your DOT Physical!)

If you read through the list and you know that you are fit and ready to get a CDL, the next step is to decide which CDL classification you need to get the truck driving job of your choice.
