Determination of respondent, dated July 12, 1966, revoking petitioner's operator's license, annulled, without costs, and matter remanded to respondent for further proceedings not inconsistent herewith. In December, 1965, petitioner, then nearly 77 years old, drove her car past a red traffic light and into a street intersection, where the car collided with at least one vehicle. After a hearing, respondent revoked petitioner's license "Pursuant to Section 510, Subdivision 3 of the Vehicle and Traffic Law — Violation of Section 1110, disobeying traffic light." However, the hearing minutes show that, at the very end of the hearing, respondent's Referee stated: "I find that your client, Feely, caused this accident, in passing the light. In view of her advanced age, I am revoking her license." Hence, we conclude that the revocation of petitioner's license, though formally imposed under section 510 (subd. 3, par. [a]) of the Vehicle and Traffic Law, was in fact based upon respondent's opinion concerning petitioner's physical or mental health, grounds applicable to administrative action under paragraph (b) of the last-mentioned section and subdivision. The record, however. yields no evidence that petitioner suffers from a mental or physical disability which would warrant suspension or revocation of her license. Petitioner's age, in itself, was an insufficient predicate for a determination that she is physically or mentally disabled under paragraph (b) (cf. Matter of Wignall v. Fletcher, 303 N.Y. 435; Matter of Breslow v. Hults, 26 A.D.2d 931). We conclude, therefore, that respondent's determination must be annulled, for otherwise respondent could accomplish under paragraph (a) that which the law forbids under paragraph (b), the suspension or revocation of a license because of mental or physical disability, but in the absence of evidence of such an impairment.
