About the Maine Tanker Test
The Tanker (N) endorsement covers liquid and gas bulk loads in Maine. 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.
