A drive assist device and method capable of preventing the confusion of a driver at a traffic signal with an arrow lamp are provided. An ECU has a section for determining whether or not it is possible to pass a signal, which determines whether or not a vehicle can pass a signal, and a signal waiting time notification control section, which determines a signal waiting time of the vehicle and displays it on a display unit when the section for determining whether or not it is possible to pass a signal determines that the vehicle cannot pass a signal. The section for determining whether or not it is possible to pass a signal determines not only a lighting time of only a red signal but also a lighting time of a red signal and an arrow lamp and a lighting time of a yellow signal subsequent thereto are determined as a no-pass time.
