Adding a Tanker (N) endorsement to your Commercial Driver’s License (CDL) opens the door to transporting liquid and gaseous loads, boosting your career in high-demand industries like fuel, agriculture, and chemicals. Unlike some endorsements, the Tanker endorsement doesn’t require Federal Motor Carrier Safety Administration (FMCSA) Entry-Level Driver Training (ELDT), making it a straightforward and affordable addition to your CDL. This ultimate guide for 2025 walks you through the process, costs, test preparation, and career benefits, plus tips to ensure success. With tanker drivers earning $45,000 to $75,000 annually and growing job opportunities, now’s the perfect time to get started.

Let’s dive into how to get your Tanker endorsement in 2025.

What is a Tanker Endorsement?

The Tanker (N) endorsement allows you to operate commercial vehicles carrying liquids or gases in tanks with an individual capacity of 1,000 gallons or more, or permanently or temporarily attached to the vehicle. This includes fuel tankers, water trucks, and chemical haulers. The endorsement is critical for safety, as tank vehicles require special handling to manage liquid surge, weight distribution, and spill prevention.

Unlike the HAZMAT or Passenger endorsements, the Tanker endorsement doesn’t require ELDT or a TSA background check, keeping the process simple and cost-effective. However, thorough preparation is essential to pass the DMV knowledge test and ensure safe operations.

Why Get a Tanker Endorsement in 2025?

Adding this endorsement offers significant advantages:

  • Higher Earnings: Tanker drivers often earn 10-25% more than standard CDL holders, with salaries averaging $45,000-$75,000, depending on region and experience.

  • Job Demand: Industries like oil, food transport, and agriculture face ongoing driver shortages, increasing opportunities.

  • Career Flexibility: Pair with a HAZMAT (H) endorsement for an “X” endorsement, unlocking even more specialized roles.

  • Quick Process: No ELDT or background checks mean you can get it faster than other endorsements.

With no major regulatory changes expected in 2025, the process remains stable, making it an ideal year to act.

Step-by-Step Process to Get Your Tanker Endorsement in 2025

Follow these steps to secure your Tanker endorsement efficiently. The process typically takes 1-2 weeks, depending on DMV scheduling.

Step 1: Confirm Eligibility

Ensure you meet the basic requirements:

  • Hold a valid CDL in good standing.

  • Be at least 21 for interstate transport (some states allow 18 for intrastate).

  • No specific background check needed, unlike HAZMAT.

Check your state’s DMV for any additional rules, like medical certifications in California or Texas.

Step 2: Study for the Tanker Knowledge Test

The Tanker endorsement requires passing a written knowledge test (typically 20-30 questions, 80% pass rate) at your DMV. Key topics include:

  • Liquid surge and vehicle stability

  • Safe loading and unloading procedures

  • Tank inspection and maintenance

  • Weight distribution and emergency response

Step 3: Schedule and Pass the DMV Knowledge Test

Contact your local DMV to schedule the test. Bring your CDL and pay the test fee ($10-$50, depending on the state). Study materials from your training course or FMCSA handbooks to ensure a first-time pass.

Step 4: Add the Endorsement to Your CDL

After passing, pay the state endorsement fee ($5-$20) at the DMV to add the “N” to your CDL. The endorsement is valid until your CDL expires (typically 5-8 years). Some states may require a new CDL card, adding a small issuance fee.
