Section 313 (subd 1, par [a]) of the Vehicle and Traffic Law provides expressly that insurance cancellation notices "shall include in type of which the face shall not be smaller than twelve point a statement that proof of financial security is required to be maintained".

(Cf. Matter of Garcia v Federal Ins. Co., 46 N.Y.2d 1040.)
