To become a tanker driver in the Pine Tree State, you must obtain a Class A or Class B CDL (Commercial Driver’s License) with a Tank Vehicles (N) endorsement. You must be at least 18 to apply for a CLP (Commercial Learner’s Permit), a certification that allows you to practice driving commercial vehicles under the supervision of a full CDL holder. The DMV requires all applicants seeking a CLP to submit identification documents, pay the licensing fees, pass a vision screening, and pass a medical exam.
Before you can get behind the wheel of an actual tanker truck, you must master general commercial driving theory and the safe operation of tanker vehicles. These subjects are discussed in the official Commercial Driver License Manual (Maine CDL Handbook 2026). Your knowledge will be evaluated on several theory tests, starting with the official General Knowledge Exam. Our Free Maine CDL Permit Practice Test can help you ace this exam on your first attempt. Many students are already training with it, and you can begin your first training session right away.
The practice test that you’re about to take includes questions similar to those you will encounter on the official Tank Vehicles Knowledge Exam. Each question includes a detailed explanation that describes the reasoning behind the correct answer. Use this feedback to learn from your mistakes and improve your knowledge through active learning. Please note this feedback in a notebook or notebook app and revisit the material during future training sessions.
