About the Ohio CDL Tanker Test Exam
The Ohio CDL Tanker Vehicles Endorsement Test is the written knowledge test for Ohio commercial drivers who need the N endorsement to operate qualifying tank vehicles carrying liquids or gases. Ohio BMV publishes the Ohio Commercial Driver License Manual HSY 7605 and requires knowledge testing for each CDL endorsement. The tanker material centers on Section 8: inspecting tanks for leaks, valves, hoses, manhole covers, vents, and emergency equipment; understanding liquid surge, outage/ullage, high center of gravity, baffles, bulkheads, smooth-bore tanks, and compartments; and driving safely through starts, stops, curves, ramps, grades, and slippery conditions. Federal CDL rules in 49 CFR Part 383 define tank endorsement testing and require at least 80% correct on each knowledge test.
