A saddled vehicle driven by a driver can include a detection device and a cruise control device for judging the other vehicles detected by the detection device and traveling in a same traffic lane as the own vehicle's traffic lane as a preceding vehicle and for automatically controlling travel of the vehicle driven by the driver so that the vehicle driven by the driver follows the preceding vehicle and keeps a preset intervehicular distance relative to the preceding vehicle. The cruise control device can obtain a forward intervehicular distance which is a distance from the vehicle driven by the driver to the preceding vehicle in a traveling direction and a side intervehicular distance which is a distance from the vehicle driven by the driver to the preceding vehicle in a vehicle width direction and can perform the automatic travel control of the vehicle driven by the driver in accordance with the forward intervehicular distance and the side intervehicular distance.
