Compared with other kinds of commercial vehicles, how stable are double and triple combinations?

Answer options

Why

Because each trailer amplifies the motion of the one in front of it, doubles and triples roll over and jackknife more easily than other commercial vehicles. Drive them smoothly and look far ahead so you can ease off or move over gradually.
