Wyoming CDL Tanker: High Center of Gravity Test 2026

A loaded tanker sits higher and rolls more easily than most commercial vehicles, and this Wyoming CDL high center of gravity test section explains exactly why. Rollover risk on a tanker climbs sharply the moment a curve or ramp is taken too fast.

Expect coverage of how liquid movement inside the tank compounds the rollover risk beyond what a solid load of the same weight would create, why tankers roll at speeds that feel safe in any other truck, and what steering corrections make a rollover more likely rather than less. WYDOT weighs this topic heavily on the tanker endorsement test.

This is arguably the single most important safety concept in tanker driving, not just a test topic. Study it until the Wyoming CDL Manual's explanation feels intuitive rather than memorized.
