What are the Requirements for CDL School?

Requirements for CDL school are relatively easy to obtain, making earning your CDL license more possible than ever before. The last few years have been rough all over, and many people are yearning for a change. Many people all over the world have used the COVID-19 Pandemic as an opportunity to change careers, and the United States is no exception. As supply chain issues situate themselves, there will be a boom in demand for drivers with CDL licenses, which could lead to lucrative careers for those who get the training now. Read on to learn more about the requirements for CDL school. 

Requirements for CDL school 

1.Be 21 or Over

Technically, anyone over the age of 18 is allowed to test for the CDL, but drivers must be 21 or over to cross state lines, which accounts for most of the well-paid shipping jobs. This rule makes sense when you consider how experienced a driver must be to handle the dangers of driving a rig responsibly. A few more years on the road can mean a big difference. 

2. Have a Valid US Driver’s License

To drive a truck, you must know how to drive a car. You must already have a valid license for regular non-commercial vehicles to prove your baseline knowledge of the rules of the road.  

3. No DUIs in Past 5 Years

To get your CDL, you must prove you are a responsible driver. While felonies do not automatically disqualify you, you must not have been convicted of a DUI in the past 5 years to operate these large vehicles.

The Federal Motor Carrier Safety Administration ( FMCSA), sets regulations for disqualifications for all CDL holders. It should be noted that if your past criminal history includes a crime involving a motor vehicle, you may be unable to obtain a CDL.

4. Pass the DOT Drug Screen and DOT Physical

Drivers must be in relatively good mental and physical health, so drivers must pass medical screens conducted by the Department of Transportation (DOT) and obtain a medical card before CDL eligibility. The two tests all drivers need to pass are the DOT Physical and the DOT Drug Screen.

DOT Physical Exams test the following:

  • Vision- Must meet 20/40 requirement on the Snellen eye test in both eyes with or without corrective lenses.
  • Color distinction– Must identify hues of red, green, and yellow for road safety reasons.
  • Blood pressure- Must be less than 140/90 to qualify. 
  • Hearing- Must hear a forced whisper from five feet away. Hearing aids are allowed.
  • Cardiovascular health- Must have permission from doctor or cardiologist if you’ve had any cardiovascular health issues in the past
  • Urinalysis- Comply with a urine test to test dehydration, proteins, glucose levels, and the presence of drugs 
  • Physical endurance- Must be able to sit for long periods, climb in and out of a cab, lift heavy objects. 
  • Medical history- mention past surgeries list all medications or any other factors that could make driving unsafe.

To prepare for this exam, medical professionals recommend focusing on healthy eating and cutting down on sugar, caffeine, and salt in the weeks leading up to your test. Take all prescription medications regularly to operate as your best self. Get an eye exam to ensure your vision is working as best as it can, and if you wear glasses or contact lenses, make sure your prescriptions are in date. Make sure to bring a record of your complete medical history to give the examiner as much information about your health as possible. You can check the FMCSA registry to find a certified examiner in your area. 

DOT Drug Screens search for five classes of drugs: Marijuana, Cocaine, Opiates (mainly opium and codeine derivatives), amphetamines, methamphetamines, and PCP. Any failure of this test will have the driver disqualified from CDL classes. 

Potential students should also know many CDL drivers are also randomly tested throughout the year, and carriers will test any driver who appears under the influence of drugs or alcohol. 

5. Present Proof of Citizenship and Pass a Background Check

Potential students will need to prove citizenship or lawful permanent residency through a social security card, birth certificate, green card, or other documents. The list of documents accepted as proof of your identity varies even more by state so it’s best to consult your state CDL manual or DMV website for the latest information on valid documents. Other commonly accepted documents include A valid US passport, USCIS American Indian Card, valid military ID card, and Temporary Resident ID Card. 

Proof of residency requirements will vary by state as well. Some states require drivers to provide a copy of a single utility bill while others require two or three different documents. Either way, the address on the documents must match the address on the CDL application.

Some CDL endorsements may require additional state and background checks. For example, the Hazmat endorsement must conduct background checks to ensure drivers can be trusted to transport hazardous material across state lines. School bus drivers may also require background checks to ensure students’ safety.
