According to the CDL manual, what must a driver do when any vehicle, including a tank vehicle, starts to skid?
Tanker (N) Endorsement • Free CDL Practice Question
Regulation
49 CFR 383.119(i); AAMVA CDL Manual Section 8.3.5, p.8-8-2
Why This Matters
A skid in a liquid tanker can escalate into a jackknife or rollover within seconds because of surge, so the manual's instruction to act rather than hesitate reflects how little margin a tanker driver has once control starts to slip.
