DECISION JUDGMENT
ADJUDGED that the determination is confirmed, the petition is denied, and the proceeding is dismissed on the merits, with costs.
It is well established that to annul an administrative determination made after a hearing, the court must be satisfied, after reviewing the record as a whole, that it lacks substantial evidence to support the determination ( see 300 Gramatan Ave. Assoc. v. State Div. of Human Rights, 45 N.Y.2d 176, 181; Matter of Scara-Mix, Inc. v. Martinez, 305 A.D.2d 418; Matter of Casalino Interior Demolition Corp. v. New York State Dept. of Motor Vehicles, 261 A.D.2d 615). A reviewing court will not undertake the functions of weighing evidence and assessing credibility, as those matters are committed to the Administrative Law Judge ( see Matter of Anthony Grace Sons v. New York State Dept. of Motor Vehicles, 266 A.D.2d 456).
The testimony of the traffic enforcement agent who issued the summonses regarding the location of the weighing site and his training, accompanied by certificates establishing the accuracy of the devices he used in weighing the petitioner's vehicle, provided sufficient basis for the determination of the Administrative Law Judge ( see Matter of Scara-Mix, Inc. v. Martinez, supra; Matter of RD Equip. Leasing Co. v. Adduci, 220 A.D.2d 900; see also Matter of DeOliveira v. New York State Dept. of Motor Vehicles., 271 A.D.2d 607). As the determination is supported by substantial evidence, we decline to disturb it.
Contrary to the petitioner's contention, it waived its jurisdictional objections when it appeared and participated in the hearing on the merits ( see Matter of United States Power Squadrons v. State Human Rights Appeal Bd., 84 A.D.2d 318, affd 59 N.Y.2d 401). In any event, administrative proceedings are not governed by the service requirements of the CPLR and, thus, service of the tickets upon the vehicle's driver was sufficient to confer personal jurisdiction over the petitioner ( see Matter of Miller v. Schwartz, 72 N.Y.2d 869).
The petitioner's remaining contentions are without merit.
