DRIVING ASSIST DEVICE, METHOD AND PROGRAM

A driving assist device is mounted on a vehicle. The driving assist device includes a derivation unit that derives driving characteristics of a user who drives the vehicle, a determination unit that determines, based on the driving characteristics, whether a driving operation by the user corresponds to a driving operation that falls outside the driving characteristics, and an inhibition unit that performs, in a case where the determination unit determines that the driving operation by the user corresponds to a driving operation that falls outside the driving characteristics, control for inhibiting traveling based on the driving operation by the user.
