Regulation
49 CFR 383.111(a)(3) (CMV safety control systems); AAMVA CDL Manual (nhcdm.pdf) Section 2.18.6 to 2.18.8, pp.2-35 to 2-36 — ABS is covered under the manual's Section 2.18 'Antilock Braking Systems,' distinct from Section 2.19 'Skid Control and Recovery,'
Why This Matters
A common and dangerous misunderstanding is assuming ABS makes a vehicle safer in every kind of skid. In reality it only addresses brake-induced wheel lockup, so a driver who over-accelerates on ice or over-steers into a curve can still skid even with fully functioning ABS.
