Judgment unanimously affirmed. Memorandum: The hearing court properly denied defendant's motion to suppress evidence found during a search of his car. The police validly stopped the car after observing it in the wrong lane of traffic (see, People v Ingle, 36 N.Y.2d 413, 420; People v. Holstein, 154 A.D.2d 905, lv denied 74 N.Y.2d 949). The police had probable cause to arrest defendant for driving while intoxicated based upon his erratic driving, his physical appearance and his failing of the field sobriety tests (see, People v. Van Dusen, 89 A.D.2d 649). Once the police discovered a .22 caliber handgun in defendant's boot during a frisk incident to that arrest, the police had probable cause entitling them to search the passenger compartment of the car and any containers found therein for further contraband under the automobile exception to the warrant requirement (see, People v. Blasich, 73 N.Y.2d 673, 678; People v. Ellis, 62 N.Y.2d 393, 397-398; People v Langen, 60 N.Y.2d 170, 180-182, cert denied 465 U.S. 1028; People v. Belton, 55 N.Y.2d 49, 53-55).
