A drowsiness prevention device includes a psychological state estimator and a controller. The psychological state estimator estimates a psychological state of an occupant, based on a state of the occupant detected by a detection device. The controller causes an output device to output a first warning and a second warning which are for alerting the occupant. The psychological state estimator estimates a first psychological state of the occupant which is before the first warning is output and a second psychological state of the occupant which is after the first warning is output. The controller determines details of a second warning, based on only the second psychological state or based on both the first psychological state and the second psychological state.
