A driver assist ECU executes a collision avoidance assist operation for avoiding a collision between a host vehicle and an object when a collision determination condition that is satisfied when the host vehicle is predicted to collide with the object is satisfied. The driver assist ECU recognizes a speed limit applied on a lane on which the host vehicle is traveling, and when a current speed limit that is newly recognized at a current point in time is lower than a past speed limit that had been recognized until immediately before the current point in time, changes the collision determination condition to a condition that is easily satisfied, in order for the collision avoidance assist operation to be performed at an earlier timing than when the current speed limit is not lower than the past speed limit.
