True or False: During a CMV rollover, the trailer typically begins to roll first.

Answer: A — True

The statement is true because in the event of a commercial motor vehicle (CMV) rollover, the trailer often experiences the initial tipping or rolling motion first. This occurs due to the dynamics and weight distribution of the vehicle. When a sudden maneuver or shift in weight occurs, such as during a sharp turn or evasive action, the trailer's higher center of gravity and its location behind the cab can cause it to begin rolling before the truck itself. The inherent design of many truck and trailer combinations makes them susceptible to this type of rollover. For instance, if the trailer is loaded unevenly or if the cargo shifts, these factors can exacerbate the risk of the trailer rolling first. Understanding this behavior is crucial for CMV drivers, as it can help them take preventative measures while driving, such as reducing speed while cornering and ensuring proper load distribution to maintain stability.
