About the Kentucky Tanker Test
The Tanker (N) endorsement covers liquid and gas bulk loads in Kentucky. A partially full tank handles like nothing else on the road, so the test focuses on liquid surge, a high center of gravity, outage, baffles, and smooth braking.
PM
From Pedro, behind the wheelI run tankers, and liquid surge is no joke — a half-empty smooth-bore tank will push you through an intersection after you've stopped. Take the outage and baffle questions slow.

License fees and retake rules are set by Kentucky and change from time to time, so check the official source below for current amounts before you go in.
