Abstract
Disclosed is a drive assistance device capable of performing proper drive assistance by reducing unnecessary drive assistance operations. The drive assistance device performs drive assistance relative to stopping of a vehicle at an intersection. When the vehicle approaches the intersection where an arrow lamp device is installed at a traffic signal, if the necessity of drive assistance for stimulating a driver to stop at the signal according to lighting of the arrow lamp device differs depending on a route of the vehicle, the start timing of the drive assistance operation is delayed and drive assistance is executed. Therefore, an unnecessary drive assistance operation can be suppressed.
