A driver assumes that because their tanker has baffles installed, they can take curves faster without any added rollover risk from liquid movement. What is the flaw in this assumption?

49 CFR 383.119(c) (differences in handling of baffled/compartmented tank interiors) and 383.119(f) (effects of road curvature on handling); AAMVA CDL Manual Section 8.2.1 (High Center of Gravity, p.8-8-1), Section 8.2.4 (Baffled Tanks, p.8-8-2), and Secti

Overconfidence from having baffles installed is a real contributor to tank vehicle rollovers on curves. Because baffles don't stop side-to-side surge, a curve speed that would be safe for other vehicles can still be too fast for a loaded tanker. This is why tank endorsement training tells drivers to slow down for curves regardless of baffle equipment.
