CDL Endorsements: Which Ones Should You Get?
If you’re working toward your Commercial Driver’s License (CDL), you’ve likely heard about endorsements—specialized certifications that expand your driving privileges. Choosing the right endorsements is essential for aligning your CDL with your career goals. This CDL endorsement guide will help you understand which endorsements are available, what they allow you to do, and which ones are worth pursuing based on your professional objectives.
What Is a CDL Endorsement?
CDL endorsements are additional qualifications that appear on your commercial driver’s license. These endorsements are required if you want to transport certain types of cargo or operate specialized vehicles. To earn an endorsement, you must pass additional written tests—and in some cases, skills tests—administered by your state’s Department of Motor Vehicles (DMV) or equivalent agency.
Top CDL Endorsements to Consider
This CDL endorsement guide focuses on the most common and valuable endorsements for working professionals. Selecting the right combination can open up more job opportunities and increase your earning potential.
1. H Endorsement – Hazardous Materials (HazMat)
The H endorsement is required if you transport hazardous materials such as flammable liquids, explosives, or toxic substances. This endorsement is in high demand and can significantly boost your pay rate. To obtain it, you’ll need to pass a written exam and undergo a Transportation Security Administration (TSA) background check.
2. N Endorsement – Tank Vehicles
The N endorsement allows you to drive tank vehicles that carry liquid or gaseous materials. It’s often paired with the HazMat endorsement (H), especially if you plan to haul fuel or chemicals. Tanker jobs tend to offer higher wages due to the complexity and responsibility involved in transporting liquid cargo.
3. X Endorsement – Tanker and HazMat Combination
The X endorsement combines the N (Tank Vehicles) and H (HazMat) endorsements. It’s ideal for drivers looking to maximize their job opportunities in industries like chemical transport, fuel delivery, and other high-risk cargo operations. Getting the X endorsement requires passing both the HazMat and Tanker written tests and completing TSA clearance.
4. T Endorsement – Double/Triple Trailers
The T endorsement is necessary for drivers who want to haul double or triple trailers. These are commonly used in long-haul freight and regional delivery routes. While the maneuvering is more complex, many carriers offer bonuses or higher pay for drivers with this endorsement due to the increased responsibility.
5. P Endorsement – Passenger Vehicles
If you’re interested in driving buses, shuttles, or other passenger transport vehicles, the P endorsement is essential. This endorsement is commonly required for transit bus drivers, school bus operators (along with the S endorsement), and charter bus companies. You’ll need to pass both a written test and a skills test in a passenger vehicle to qualify.
6. S Endorsement – School Bus
The S endorsement is required to operate a school bus. In addition to the P endorsement, you must pass background checks, a written test, and a specialized skills test. School districts and private contractors often require this endorsement for employment in student transport services.
How to Choose the Right CDL Endorsements
When deciding which CDL endorsements to pursue, consider your career goals, the region in which you plan to work, and the types of jobs in demand. Here are a few tips:
- Research job listings: Look at job postings in your area to see which endorsements employers require or prefer.
- Talk to industry professionals: Connect with experienced drivers or recruiters to understand which endorsements offer the best opportunities in your field.
- Consider long-term goals: If you plan to move into specialized transport, such as HazMat or passenger service, obtaining those endorsements early can set you up for future success.
Getting additional endorsements can require extra time and effort, but the payoff in terms of job flexibility and salary potential is often well worth it. Whether you’re new to commercial driving or looking to expand your qualifications, this CDL endorsement guide can serve as a roadmap for your career development.
