In a vehicle safety running apparatus, when a route guidance by a navigation system is not in operation, a determination on passableness is carried out as a target on a branch road of a plurality of branch roads branched from an intersection ahead of the subject vehicle which has lowest with respect to the degree of difficulty in running or a branch road having a smallest intersection angle formed by a road on which the subject vehicle is advancing and the branch road and a curve on the branch road, whereby an automatic deceleration control can be performed or an alarm can be given to the driver even when the route guidance is not in operation, and moreover the automatic deceleration control and/or alarming the driver is prevented from being performed unnecessarily, thereby making it possible to suppress to a minimum level the physical disorder that the driver may feel.
