A driver assistance device comprises a travel route calculator, a danger zone identifier, an information acquisitor, a speed determiner, and a speed controller. The travel route calculator is configured to calculate a travel route to a destination set by an occupant of a vehicle. The danger zone identifier is configured to identify a danger zone on the travel route. The information acquisitor is configured to acquire, from at least one preceding vehicle traveling ahead on the travel route, travel and road surface information at a time when the preceding vehicle has traveled in the danger zone. The speed determiner is configured to, based on the travel and road surface information, determine a safe-travel speed at which the vehicle can travel in the danger zone safely. The speed controller is configured to control, with the safe-travel speed, a travel speed of the vehicle when the vehicle travels in the danger zone.
