Definition

Why it matters
Drivers must recognize ABS warning lamps and understand that ABS supports, but does not replace, safe braking technique.
ABS in CDL training
CDL students should be able to recognize this term, explain it in plain language, and connect it to safe vehicle operation, inspection, licensing, or freight work as applicable. Review the term in context and practice using it during classroom study and hands-on training.
