🎯 주제별 연습
Inspecting Tank Vehicles
Inspecting a tank vehicle: checking for leaks (you cannot drive a leaking tank), and checking the special-purpose and emergency equipment tank vehicles carry (vapor-recovery, special cut-off systems, etc.).
Driving Tank Vehicles
Why tank vehicles are harder to drive: the high center of gravity (rollover risk), the danger of liquid surge in a partially filled tank, bulkheads vs baffled vs smooth-bore (un-baffled) tanks, outage (room for the liquid to expand), and how much you can load.
Safe Driving Rules
Driving a tank vehicle safely: drive smoothly, control surge when braking (brake early, keep extra following distance), slow down for curves below the posted speed, allow for a longer stopping distance, and recover from skids.

Study Section 8 (Tank Vehicles)
Cover inspecting tank vehicles (leaks, special equipment, vapor/pressure), driving safely with a high center of gravity and liquid surge (baffled vs. smooth-bore/unbaffled tanks, outage, density), and emergency handling. Bulkheaded tanks and partial loads (front-to-back vs. side-to-side surge) are heavily tested.

Pass the Tank Vehicles knowledge test (in English) at your DMV
About 20 questions, 80% to pass. This endorsement is knowledge-test only. Fees and scheduling vary by state.
💡 시험 당일 팁
- •Learn the key English terms even if you study in Chinese/Spanish: liquid surge, baffle, smooth-bore (unbaffled) tank, bulkhead, outage, center of gravity, gallons.
- •Master the high-stakes safety facts: tankers have a high center of gravity and liquid surge, so slow down well below posted curve speeds and brake early; smooth-bore (unbaffled) tanks have the worst forward-and-back surge — wait for the surge to settle before easing off the brake; and never over-fill — you must leave outage for the liquid to expand.
- •Know why you can't always fill a tank: liquids expand as they warm (you must leave outage), and the legal weight depends on the liquid's density — a tank that fills to legal weight with one product would be overweight with a denser one.
