Earning your CDL is an important process if you plan to hit the streets in a commercial motorized vehicle (CMV). It all starts with knowing about the rules and requirements set by the Federal Motor Carrier Safety Administration (FMCSA). Each state has their own application process, fees, and forms, but they all adhere to the federal requirements of the FMCSA. Learn about the different requirements so you can be well on your way towards a career in truck driving.

To be able to apply for a CDL, you must first obtain a CLP. The CLP must be held for a minimum of 14 days (minimum days differ from state to state). A road skills test must be passed beforehand, as well as any additional knowledge or skills exams for endorsements.
Additional compliance requirements issued by the FMCSA include:
To be able to drive a commercial motor vehicle, a truck driver must have the physical capabilities of doing so, alongside the various non-driving job duties. Being a trucker means unloading and loading freight as well as driving long hours. This can cause sleep deprivation, high stress levels, relationship challenges, and physical wear and tear. With that being said, making sure you are physically and medically sound for the position is important.
Physical and medical requirements will be examined by an approved Medical Examiner, listed on the FMCSA National Registry. The Department of Transportation (DOT) medical exam will look over the following:
The visual acuity measurement should be at least 20/40 in each eye, with or without correction (includes eyeglasses or contacts). Also, there must be at least 70 degrees peripheral in the horizontal meridian measured in each eye.
Truckers should be able to hear a forced whisper from more than 5 feet away, in at least one ear. Hearing aids are permitted to help hearing.
Truck drivers that require a needle injected insulin do not meet requirements. Although, diabetic drivers that take oral medications are permitted.
A driver with blood pressure below 140/90, will be certified with a 2 year card. Stage 1 high blood pressure of 140-159/90-99 will be certified a 1 year card. Stage 2 high blood pressure of 160-179/100-109 will be issued a temporary 3 month certificate (at examiners discretion). Stage 3 high blood pressure >180/110 will result in a disqualification.
Blood sugar levels are required to be less than 10%. Certificates will be issued at the discretion of the examiner for levels above 10%.
Sleep apnea may result in a disqualification unless it is demonstrated that the condition is under control. This includes a recent annual sleep study and release from a physician.
These are some of the basic physical qualifications for commercial drivers. Other factors may be examined such as recent major surgeries, loss of limbs, etc.
Depending on the type of commerce you intend to drive, you aren’t required to submit a Medical Examination Certificate, unless required by an employer. Most CDL holders are non-excepted drivers and require a Medical Examination Card. To determine if you are excepted, you must self-certify:
Interstate: Operating inside or outside the state you obtain a CDL in.
Intrastate: Operating within the borders of the state you obtain a CDL in.
There are a few different written exams to pass when working towards a CLP or CDL. The first is the general knowledge test, followed by an air brakes test, and one or more CDL endorsement tests. To help you prepare for these tests, we have put together a number of free practice exams:
A road skills exam is required to demonstrate knowledge and skills in regards to pre-trip inspections, basic vehicle control, and on-road driving. Knowing the vehicle is safe to drive, full control of the vehicle, and safe driving habits will be assessed. The road skills test can be taken after a CLP is earned.
The road skills test must be taken in the type of commercial vehicle to be licensed in. This means bringing a Class A, Class B, or Class C commercial vehicle.
In addition to the requirements outlined by your employer when trying to find top CDL drivers, you should also be aware of your state requirements. For specific CDL requirements for your state, refer to your state’s official 2024 CDL manual:
