In a triple trailer combination, which trailer is most likely to roll over in a sudden lane change?
a.The first trailer
b.The second trailer
c.The third (last) trailer
d.All trailers roll over equally
Explanation
Due to rearward amplification and the crack-the-whip effect, the last trailer in a multi-trailer combination experiences the greatest lateral force during sudden steering maneuvers. In triples, the third trailer can amplify steering input up to three times.
