Any single vehicle with a gross vehicle weight rating (GVWR) of 26,001 pounds or more.
A combination vehicle with a gross combination weight rating (GCWR) of 26,001 or more pounds, provided the GVWR of the vehicle(s) being towed is in excess of 10,000 pounds.
A vehicle designed to transport 16 or more passengers (including the driver).
Any size vehicle which requires hazardous material placards or is carrying material listed as a select agent or toxin in 42 CFR part 73. Federal regulations through the Department of Homeland Security require a background check and fingerprinting for the Hazardous Materials endorsement. Contact your local department of driver licensing for more information.
There is a fourth type of vehicle not included in this question, which is, "Any size vehicle which requires hazardous material placards or is carrying material listed as a select agent or toxin in 42 CFR part 73"
Combination Hazardous Materials and Tank Vehicle (X). Drivers of tank vehicles who haul hazardous materials or waste in amounts requiring placards must add an X endorsement to their CDL, showing that they have passed the special knowledge examinations for both tank vehicles and hazardous materials.
To be honest, I'm not sure why they created the X endorsement. It's simply a combination of both Hazmat and Tanker endorsements.
Class A Combination Vehicles. Any combination of vehicles with a gross combination weight rating (GCWR) of 26,001 or more pounds falls in Group A provided the GVWR of the vehicle(s) being towed is more than 10,000 pounds.
If you operate in both excepted interstate commerce and non-excepted interstate commerce, you must choose non-excepted interstate commerce to be qualified to operate in both types of interstate commerce.
Most drivers are non-exempted drivers and must have a valid Federal medical examiner’s certificate.
You are not allowed to hold a mobile telephone to conduct a voice communication or dial a mobile telephone by pressing more than a single button when driving. You are not allowed to send or read text messages while driving.
This is one of the biggest problems on our highways today. Distracted drivers have changed or destroyed an untold number of lives. Please, please take this seriously!

Drivers Who Must Obtain A CDL
Any driver of the following vehicles must possess a Commercial Driver’s License (CDL):
Any combination of vehicles with a gross combination weight rating (GCWR)** of
26,001 or more pounds, providing the gross vehicle weight rating (GVWR)* of the
vehicle being towed is in excess of 10,000 pounds.
Any single vehicle with a GVWR of 26,001 or more pounds or any such vehicle towing
another not in excess of 10,000 pounds
Any vehicle, regardless of size, designed to transport 16 or more persons, including the driver.
Any vehicle required by federal regulations to be placarded while transporting hazardous materials.
GVWR - Gross Vehicle Weight Rating - Value specified by the manufacturer as the maximum loaded weight of a single vehicle or combination of vehicles.
GCWR - Gross Combination Weight Rating - Value specified by the manufacturer as the GVWR of the power unit plus the GVWR of the towed unit or units.
Drivers Exempt from Obtaining a CDL
Under state and federal law, certain drivers are not subject to the requirements of the CDL program. The Federal Motor Carrier Safety Administration has determined that these exemptions will not diminish the safe operation of commercial vehicles on the highways. However, these drivers are still required to possess the proper class license for the vehicle they are operating.
The following vehicle operators are not required to obtain a CDL:
Farm Vehicle/Equipment Operators - This exemption covers farming operations (as noted below) and does not apply to commercial grain haulers or other types of non-farm use. This exemption only applies when farm vehicles are:
Controlled and operated by a farmer, the farmer’s family or an employee
Used to transport farm products, equipment or supplies to or from a farm (including nurseries and aquacultures)
Used within 150 air miles of the farm
Not used in the operations of a common or contract carrier or for other commercial purposes
Emergency Equipment/Vehicle Operators - Because most emergency organizations have extensive initial training and retraining requirements for their equipment operators, states waives CDL requirements for operators of emergency equipment when responding to or returning from an emergency necessary to preserve life and property.
Military Vehicle Operators - Active duty military personnel operating military vehicles for military purposes.
Recreational Vehicle Operators - Recreational vehicle operators, when using the vehicle primarily for personal use.
Driver License Classifications (CDL and NON-CDL)
Class A - Combination vehicles - GCWR of 26,001 or more pounds providing the GVWR of the vehicle being towed is in excess of 10,000 pounds.
Class B - Single vehicle with a GVWR of 26,001 or more pounds or any such vehicle towing another not in excess of 10,000 pounds.
Class C - Single vehicle with a GVWR of at least 16,001 pounds but less than 26,001 pounds.
Class D - Single vehicle with a GVWR of less than 16,001 pounds.

Hands-free devices or Bluetooth technology is allowed for persons over age 18. Even using hands-free technology is considered a distraction while driving and can be dangerous. If you must make a phone call, even with hands-free technology, it is recommended that you pull off to the side of the road before making the call.
