About the Michigan CDL Tanker Exam
The Michigan CDL Tank Vehicles Endorsement Test is the written knowledge exam for commercial drivers who need N endorsement authority to operate qualifying tank vehicles. Michigan's CDL manual says a tank endorsement is required for certain Class A or Class B CDL vehicles that haul liquid or gaseous material in tanks with individual rated capacity over 119 gallons and aggregate capacity of 1,000 gallons or more, whether permanently or temporarily attached. It is also required for covered Class C hazardous-material liquid or gas tank operations. The test content comes from Michigan CDL Manual Section 8 and federal 49 CFR Part 383 tank endorsement standards, including inspections, leaks, valves, manhole covers, vents, special equipment, liquid surge, high center of gravity, bulkheads, baffles, smooth bore tanks, outage, loading factors, braking, curves, ramps, stopping distance, skids, and emergency systems.

Frequently Asked Questions
Who needs the Michigan CDL tank vehicles endorsement?
Michigan's CDL manual says the tank endorsement is required for certain Class A or Class B CDL vehicles hauling liquid or gaseous material in tanks with individual rated capacity over 119 gallons and aggregate capacity of 1,000 gallons or more. The tank may be permanently or temporarily attached, and the cargo does not have to be hazardous. Covered Class C hazardous-material liquid or gas tank operations can also require tank authority.
What score do I need to pass the Michigan CDL tanker knowledge test?
Federal CDL rules in 49 CFR 383.135 require at least 80 percent correct on CDL knowledge tests. Michigan CDL materials use that same 80 percent passing standard.
What is liquid surge?
Liquid surge is the movement of liquid inside a partially filled tank. Michigan's CDL manual warns that when the wave hits the end of the tank, it can push the truck in the direction the wave is moving. On ice, that force can shove a stopped truck into an intersection.
What is the difference between bulkheads and baffles?
Bulkheads divide a liquid tank into smaller tanks or compartments, so loading and unloading require careful weight distribution. Baffles are internal walls with holes that let liquid flow through while helping control forward-and-back surge. Baffles do not prevent side-to-side surge.
What is outage or ullage?
Outage, also called ullage, is empty space left in the tank for liquid expansion. Michigan's manual says never to load a cargo tank totally full because liquids expand as they warm, and different liquids require different amounts of outage.
How much does the Michigan CDL tanker endorsement cost?
Michigan's fee page lists $5 for each standard CDL group designation or endorsement. Michigan materials list $10 for an X endorsement when tank vehicle and hazardous materials authority are combined. Other CDL, correction, training, or skills-test costs may also apply depending on the applicant's path.
