Second Law.
To make the car change direction you need an acceleration (a change in the velocity vector), which requires a net force (F = ma). The inward (centripetal) force is supplied by static friction between the tires and the road (F = m v^2/r). The First Law describes the tendency to go straight without that force, and the Third Law gives the action–reaction pair but does not by itself produce the turn.
