First in first, out means that the motorist who reaches the intersection first has to go first while the second driver waits for the first driver to safely exit the intersection. Intersections in traffic and roads control are a point where more than one roads cross over or intersect.
Yielding techniques are established to avoid confusions, traffic quarrels, and free traffic flow. Of course, yielding will depend on the type of intersection, traffic control signs or traffic light present on the intersection.
