[Problem] To provide a trailer roll-over prevention apparatus. [Solution] The width between 1-1 and 1-2 of a coupler of a tractor is extended to a width between 2-1 and 2-2, and preferably, the width of the upper base of the coupler is made equal to the vehicle width. Thus, if the trailer starts to roll over with the centrifugal force shown by 4-11, roll-over prevention and a safe performance similar to trucks is achieved thereby.
