 The following are the details of all the CDL requirements which is common in all US states. 

• Age Requirement: You must be at least 18 years old to drive within the state (intrastate driving) and at least 21 years old to drive in different states (interstate driving).

• Residence: You need a valid residency proof in all 50 US states.

• Identification: A valid driver’s license and Social Security number are compulsory for everyone.

• Medical Exam: You need to pass a DOT (Department of Transportation) medical exam. Passing it will give you a valid Medical Examiner’s Certificate.

• Knowledge Test: A written knowledge test is conducted for the Commercial Learner’s Permit (CLP).

• Skills Test: A road skills test is conducted, which includes a pre-trip inspection and vehicle operation. This test is mandatory to pass to earn a CDL.

There are three main classes under CDL:

1. CDL Class A -  The Class A license includes driving heavy trucks that weigh over 26,001 pounds and a trailer over 10,000 pounds.

3. CDL Class C - This includes those vehicles that carry dangerous materials, along with vehicles which has 16+ passengers in them.

CDL Endorsements

CDL endorsements are certain authorizations that give commercial drivers permission to operate specific types of vehicles. Getting some endorsements for your CDL will make you more versatile and increase your career opportunities. To obtain them, you have to pass extra written tests, and in some types, skills tests are also needed.  

1. H (HazMat or Hazardous Materials): This endorsement is required for vehicles which will be used in transporting dangerous materials such as flammable liquids, explosives, chemicals, etc. 

2. N (Tank Vehicle): This endorsement includes licensing to those vehicles which carry liquid or gaseous materials in large amounts. E.g., water, hauling fuel, or food liquids.

3. P (Passengers): As the name suggests, the Passenger endorsement issues drivers to drive passenger-carrying vehicles such as city buses, tour buses, or office shuttles. This endorsement includes a skills test along with the other standard exams.

4. S (School Bus): This is a specialized endorsement for school bus drivers. For this, you have to hold a Passenger (P) endorsement and clear complete additional testing focused on child safety and school bus driving.

5. T (Doubles/Triples): This endorsement allows you to drive double or triple trailers. This is mainly for long-haul drivers. It requires knowledge of handling larger and more complex trailer combinations.

6. X (Combination Tanker and HazMat): This is a combined endorsement that allows you to operate tank vehicles that carry hazardous materials. It gives you the benefits of both H and N endorsements.
