A motor vehicle includes a distance related speed control system, wherein if the motor vehicle is following a vehicle driving in front, a target distance from the vehicle driving in front chosen by the driver is generally set, and wherein for a distance-shortening turn signal effect time when a turn signal is set, a shortened target distance is set. The motor vehicle further has a lane departure warning system, wherein a warning that is generally activated if there is a risk of an unintentional lane departure is suppressed for a specified warning-suppressing turn signal effect time after the setting of the turn signal. The warning-suppressing turn signal effect time begins simultaneously with the distance-shortening turn signal effect time, wherein these two turn signal effect times are specified to have the same length.
