A driver preparing for the tanker endorsement exam wonders whether they need to review the Air Brakes section, since that's tested as a separate endorsement. What does the CDL manual direct?

AAMVA CDL Manual, Section 8 introduction (p. 8-8-1)

Braking a top-heavy, partially filled tank incorrectly can trigger a rollover or jackknife, so the manual's cross-reference to Air Brakes isn't a formality. A driver who skips it may pass the tank-specific material but still miss questions on how braking technique interacts with tank vehicle handling.
