Free OK CDL Tanker Vehicles Practice Test 2024
Test your knowledge of tankers with our Oklahoma CDL Tank Vehicles endorsement practice tests. This tool has been designed to help you familiarize yourself with the questions you’ll encounter at the SOK location. Each practice test consists of 20 questions based on the Tank Vehicles section of the official 2024 CDL manual (Oklahoma CDL Handbook 2024). With unlimited attempts, you can train as often as you want, being limited only by your own schedule. To maximize results, we recommend creating a daily routine consisting of multiple training sessions.
It is easier to retain important information with repetition. Consistency is always preferred over intensity, and becoming a tanker driver in Oklahoma is a long but rewarding journey. Arm yourself with a lot of patience and take small steps towards achieving your career goals. One day, you’ll pull up at the Oklahoma City Terminal in an empty tanker, waiting to be loaded with 7,000 gallons of fuel. During this time, you might want to mentally recall the various aspects of tanker driving, which you have successfully memorized in your learning phase.
Liquid surge can cause a shift in weight due to the movement of liquid inside the tank. You must drive smoothly and reduce speed ahead of sharp turns. During winter months, ice can pose a major challenge even for the most experienced commercial drivers. Stopping distance, which is already long in a tanker truck, can increase exponentially if the road is slippery. That’s why it is crucial to master the controls of your vehicle before you venture out into the Sooner State, especially if your tanker is loaded with hazardous materials. Because such cargo can be dangerous to humans and the environment, you’ll need a HazMat (H) endorsement to qualify for such jobs. Your CDL will include the combined HazMat and Tank Vehicle (X) endorsement.
As you train with our practice tests, remember your final goal: becoming a professional tanker driver who successfully handles the responsibility of transporting liquid or gaseous cargo. The Tank Vehicles endorsement knowledge test is just a piece of the puzzle. Passing it with a score of 80% or above completes the bigger picture, which sees you behind the wheel of an actual tanker, enjoying a fulfilling and rewarding career.
