Texas CDL study: Tanker questions
40 questions from the TX CDL path, each with an explanation after you answer. Part of the Texas CDL Tanker practice test.
A separate written exam at the federal 80% pass mark. States rarely publish a question count for it, so plan on knowing the whole section rather than a fixed number of items. Questions focus on liquid surge and its effect on vehicle handling, the dangers of partial loads vs. full loads, proper braking and cornering techniques for tank vehicles, baffled vs. unbaffled tanks, outage requirements (why tanks are never filled completely), and emergency procedures. If you are combining the tanker endorsement with HazMat (X endorsement), expect additional questions on hazardous liquid transport.
