The crosswind sensitivity of unladen doubles and triples combinations and their susceptibility to wind-induced offtracking and rollover.

A computer-based analysis of large combination vehicles was conducted to examine the likely dynamic response of such systems when exposed to sudden crosswind gusts. The results indicate that relatively large crosswind-related offtracking and roll responses are possible for the so-called "western" triple combination vehicle (27-ft trailers) while travelling at highway speeds under empty and certain partially-loaded conditions.
