What the Course Entails and Exam Details

The material covered for the Tanker Endorsement knowledge test focuses heavily on the specific safety regulations and operational procedures unique to driving liquid or gas tankers.

Key topics you must master include:

• Vehicle Inspection: Performing comprehensive inspections on tankers, including checking for leaks, ensuring valves are secure, and verifying the integrity of the tank itself.

• Driving Rules: Understanding how to safely drive a vehicle transporting liquids, particularly managing the effects of "surge"—the movement of liquid inside the tank when stopping, starting, or turning.

• Safe Handling: Recognizing and mitigating the risks associated with the high center of gravity typical of tankers, preventing rollovers, and maintaining stability on curves.

• Emergency Procedures: Knowing the correct response in emergencies, such as leaks, spills, or equipment malfunctions.

Our comprehensive practice tests mirror the structure and content of the official Arkansas CDL manual, focusing specifically on Section 8 (Tank Vehicles).

What to Expect in the Final Exam

When you arrive for the official tanker endorsement test at an Arkansas DFA office, you will take a computer-based knowledge exam.

Here is what to expect during the official testing process:

• Format: The exam consists of multiple-choice questions designed to assess your understanding of tanker vehicle safety and operation.

• Number of Questions: The tanker knowledge test typically contains 20 questions.

• Passing Score: You must achieve a score of at least 80%, meaning you need to answer 16 out of 20 questions correctly to pass.

• Time Limit: While usually not explicitly timed, drivers generally finish the endorsement knowledge test within 20-30 minutes.

It is important to remember that this is only a knowledge test; there is no specific skills test required solely for adding the tanker endorsement if you already hold the appropriate class of CDL.

How to Study and Exam Centers

Preparation is crucial for success on any CDL endorsement test.

Start by thoroughly reading and studying the Arkansas Commercial Driver License Manual. Pay close attention to Section 8, which is dedicated to Tank Vehicles.

Once you have reviewed the manual, take reliable practice tests repeatedly. Practice tests are highly effective because they familiarize you with the question format, identify areas where you need further study, and build your confidence.

Ensure you are consistently scoring above 80% on practice exams before scheduling your official test.

When you are ready, you must take the knowledge test in person at an Arkansas Department of Finance and Administration (DFA) Revenue Office that offers CDL testing services. Some locations may require appointments, so it is advisable to check with your local office beforehand.
