When it comes to commercial trucking, tanker driving stands out as one of the more demanding but reliable career paths. In Illinois, large companies move fuel, chemicals, and food-grade liquids between refineries and distribution centers. Employers in this sector look for drivers who hold a CDL (Commercial Driver’s License) with a Tank Vehicles (N) endorsement. Those who hold the X endorsement on their CDL have a clear advantage, as it combines the HazMat (H) and Tank Vehicles (N) endorsements into a highly respected certification.
You don’t need natural talent to manage liquid surge, and stopping distances are something you learn behind the wheel of an actual tanker. The official Commercial Driver’s License Study Guide (Illinois CDL Handbook 2026) is a comprehensive resource published by the DMV. You should read this handbook several times during your learning phase and return to it occasionally even after you have completed the licensing process. Use it to learn the basics of commercial driving and understand the responsibilities that come with this job.
