If you have ever seen a large truck, bus, or tanker on the highway and wondered how someone gets to drive it, basically, they get their Commercial Driver’s License (CDL). In the United States, a CDL is required for anyone who drives a heavy or commercial vehicle.
If you are really interested in learning more about CDL, get going with this article; you’ll get to know the important information regarding the types of commercial driver’s licenses, the requirements for getting one, and the benefits of holding such a license.
Brief History of CDL
Before 1986, there was no standard law about such licenses. Drivers could even hold more than one license from different states. This created many safety problems and made it really difficult, leaving them perplexed and making it harder for authorities to track these violations.
To solve all these confusions and loss of tracking, the Commercial Motor Vehicle Safety Act of 1986 was introduced. This law made it illegal to have more than one driver’s license and created a single national system for testing and issuing CDLs.
From that, every commercial driver had to meet uniform federal safety and testing standards.
Different Types of CDL Explained
In the United States, CDLs are classified into three main types:
- Class A
- Class B
- Class C
Each type allows the driver to operate different kinds of commercial vehicles based on their size, weight, and usage.
Class A CDL
A Class A license allows the driver to operate a combination of vehicles with a weight rating of 26,001 pounds or more, or a vehicle towing another that weighs more than 10,000 pounds. This type of license covers a wide range of vehicles, such as
- Tractor-trailers or 18-wheelers
- Flatbed trucks
- Livestock carriers
- Tanker vehicles
Drivers with a Class A CDL can drive across state lines and are usually employed in long-distance freight and logistics operations.
Class B CDL
A Class B license allows a driver to operate a single vehicle with a vehicle weight rating of 26,001 pounds or more, or a vehicle towing another that weighs less than 10,000 pounds.
Examples include:
- City buses and school buses
- Delivery trucks
- Dump trucks
- Box trucks
Many local delivery drivers and city transit operators have a Class B license.
Class C CDL
A Class C license is for smaller commercial vehicles that don’t fit into Class A or B but still carry passengers or hazardous materials.
This license is required if you drive:
- Passenger vans that carry 16 or more people (including the driver)
- Small trucks carrying hazardous materials (like chemicals or flammable liquids)
Drivers with a Class C license often work in airport shuttles, hospital transport services, and fuel delivery companies.
Requirements to Get a CDL
To obtain a CDL in the United States, you must meet a few federal and state-level requirements.
- You must be at least 18 years old to drive within the same state (intrastate).
- You must be 21 years or older to drive across states (interstate) or carry hazardous materials.
- You must hold a regular driver’s license (non-commercial license).
- You must pass a medical examination and have a valid Medical Examiner’s Certificate.
- You must obtain a Commercial Learner’s Permit (CLP) and hold it for at least 14 days before taking the test.
- You must pass both written knowledge tests and practical skills tests.
Every state conducts its own testing under federal guidelines, but there’s no need to get confused because the process remains mostly the same throughout the country.
CDL Endorsements (H, N, P, S, T, X)
Endorsements are extra permissions that allow drivers to operate specific types of vehicles or handle special materials. These endorsements are added to your CDL after passing additional written and sometimes driving tests.
- H – Hazardous Materials: For transporting chemicals, gasoline, or other dangerous goods.
- N – Tank Vehicles :Those that carry liquids or gases in tanks.
- P – Passenger :For driving buses or even vans carrying passengers.
- S – School Bus :Driving school buses safely.
- T Double/Triple Trailers: For towing more than one trailer at a time.
- X Combination of Tanker and Hazardous Materials:
Having endorsements increases your employability and often brings higher pay.
