Abstract: A rollover predictor judgment device (30) for a combination vehicle (1) includes a lateral acceleration sensor (26), a yaw rate sensor (27), an articulate angle sensor (23), and a judgment device in a form of a retarder controller (32). The judgment device judges that the combination vehicle is in a rollover predictor status when a first lateral acceleration calculated based on a detection value of the lateral acceleration sensor (26) is a first threshold or more or when a second lateral acceleration calculated based on a detection value of the yaw rate sensor (27) and a detection value of the articulate angle sensor (23) is a second threshold or more.
