How does the stopping distance of a doubles/triples combination compare to a single trailer, and why?

DOUBLES/TRIPLES STOPPING: Stopping a multi-trailer combination requires more care: GREATER LENGTH AND WEIGHT mean more momentum to stop; HARD BRAKING risks: trailer instability, jackknifing, and triggering the 'crack-the-whip' effect (sudden deceleration can cause rear trailers to swing); EMPTY/LIGHTLY LOADED trailers can lock up and skid more easily; PROPER BRAKING: Brake SMOOTHLY and EARLY; anticipate stops well in advance; avoid hard, sudden braking; maintain steady, controlled deceleration; allow EXTRA following distance and stopping distance; FOLLOWING DISTANCE: The longer combination needs more space ahead; rule of thumb — at least 1 second per 10 feet of vehicle length under 40 mph, plus more for higher speeds and adverse conditions; ANTI-LOCK BRAKES (ABS) help prevent wheel lockup but don't eliminate the need for smooth braking; STABILITY: Sudden hard braking is one of the maneuvers that can destabilize a multi-trailer set; the key is anticipation and smooth, gradual braking with generous following distance; doubles/triples drivers must plan stops early and brake gently to maintain control of the entire combination.
