Ohio is a top-10 corn producer—and tanker drivers are essential to agriculture. Liquid nitrogen fertilizers move daily from terminals to farms across the state. Beyond agriculture, Ohio’s refineries and fuel distribution networks along I-71, I-75, I-77, and I-80 create steady demand for tanker-endorsed CDL holders.
What the N endorsement allows: You can drive vehicles transporting liquids or gases in tanks with individual capacity over 119 gallons and aggregate capacity of 1,000+ gallons. Without this endorsement, you cannot legally haul any bulk liquid cargo in Ohio.
Ohio employers hiring tanker drivers:
- Fuel/petroleum: Marathon Petroleum (Findlay headquarters), BP-Husky Toledo Refinery, regional fuel distributors
- Agriculture: Co-ops across western Ohio, fertilizer distributors, ethanol plants
- Food-grade: Dairy transport, liquid sweeteners, vegetable oil haulers
- Chemical: Dow, Lubrizol (Wickliffe), industrial chemical transport
What to expect on the official Ohio Tank Vehicles test:
- Questions: 20 multiple-choice
- Passing score: 80%
- Topics covered: Liquid surge and vehicle handling, tank inspection, loading/unloading, baffled vs. unbaffled tanks, emergency procedures
- Administered by: Ohio Bureau of Motor Vehicles (BMV)
Consider the X endorsement: Adding the HazMat (H) endorsement to your Tank (N) gives you the “X” endorsement—required for hauling hazardous liquids like fuel, anhydrous ammonia, and liquid fertilizers. This combination significantly expands your job options in Ohio’s agriculture and energy sectors.
