OPINION OF THE COURT
Weiss, J.During the early morning hours of January 27,1982, Columbia County Deputy Sheriff Vincent Sacco, Sr., observed an approaching vehicle traveling at a speed in excess of 70 miles per hour on Route 82, as verified by radar. Sacco commenced pursuit with siren and flashing lights activated and eventually *195drew within 20 feet of the vehicle. The vehicle eventually reduced its speed to 30 miles per hour, veered onto the shoulder several times, and then straddled a double solid dividing line before turning onto Livingston Road, on which it proceeded approximately 200 feet before turning into a driveway and directly into a garage. Sacco was close behind and observed petitioner stagger from the car and enter the house. The garage door was electronically closed before Sacco could address petitioner. Petitioner’s wife admitted Sacco and another deputy sheriff to an inside front hallway. No warrant had been obtained. Sacco requested petitioner’s wife to summon her husband and, after approximately one minute, he followed her upstairs to find petitioner lying in his bed. Petitioner, who smelled strongly of alcohol, was then placed under arrest. He refused repeated requests to submit to a chemical breath test for alcohol.
After a February 3, 1982 license revocation hearing, the hearing officer determined that petitioner’s license should be revoked after finding that there was reasonable cause to believe petitioner was driving while intoxicated, that exigent circumstances justified the warrantless arrest, and that, despite appropriate warnings, petitioner refused to submit to a chemical test within the meaning of subdivision 2 of section 1194 of the Vehicle and Traffic Law. This determination was upheld by both the administrative appeals board and respondent Commissioner of Motor Vehicles. Petitioner commenced the instant CPLR article 78 proceeding seeking to annul the revocation order.
Petitioner has attacked the validity of the warrantless arrest at home by claiming that his Fourth Amendment right against unreasonable searches and seizures was violated. We disagree. As a predicate to license revocation, it must be established, in addition to due warning and refusal, that there were reasonable grounds for the arrest and that the arrest was lawful (Vehicle and Traffic Law, § 1194, subd 3, par a; Kowanes v State of New York Dept. of Motor Vehicles, 54 AD2d 611, 612). The record confirms that the deputies had probable cause to believe that petitioner was driving while intoxicated in violation of section 1192 of the Vehicle and Traffic Law (People v Brockum, 88 AD2d 697; People v Abramowitz, 58 AD2d 921, 922). The deputy sheriff’s description of petitioner’s erratic driving and staggering from the vehicle provided ample basis for this determination. The issue thus distills to whether the circumstances justified the warrantless arrest.
It is now well established that warrantless arrests in the home are prohibited by the Fourth Amendment absent a showing of *196probable cause and exigent circumstances (Payton v New York, 445 US 573). The scope of the exigent circumstances exception justifying a warrantless home arrest has recently been reviewed by the United States Supreme Court in factual circumstances strikingly similar to the instant case. In Welsh v Wisconsin (466 US —, 104 S Ct 2091), a driver abandoned his car after swerving off the road. The police who arrived shortly thereafter were informed by a witness that the driver of the abandoned vehicle was either inebriated or very sick. Without obtaining a warrant, the police proceeded directly to the driver’s nearby home, where they were admitted, by his stepdaughter. They proceeded upstairs to the driver’s bedroom and found him lying in bed. The driver was arrested and, because he refused to submit to a breathalyzer test, his driver’s license was revoked under Wisconsin law. The Supreme Court concluded that the arrest was unlawful since it was not compelled by exigent circumstances. The court emphasized that the gravity of the underlying offense was an important factor in determining whether any exigency existed (supra, p _, p 2098). Since Wisconsin elected to classify the first offense for driving while intoxicated as a noncriminal, civil forfeiture offense for which no imprisonment was possible, no exigency was presented. This held true, notwithstanding the fact that evidence of the driver’s blood alcohol level might have dissipated while the police endeavored to obtain a warrant.
The instant case is readily distinguishable from Welsh in which the Supreme Court noted that the penalty imposed by a State for a particular offense was “the best indication of the state’s interest in precipitating an arrest” (supra, p _, p 2100). New York classifies a first offense for driving while intoxicated as a misdemeanor, punishable by imprisonment for not more than one year and/or a fine of not less than $350 nor more than $500 (Vehicle and Traffic Law, § 1192, subd 5). This classification is reflective of the State’s profound and grave concern to remove the incapacitated driver from the State’s highways (see L 1981, ch 910, § 1). By invalidating the arrest in Welsh, the Supreme Court did not intend to suggest that deterrence of drunk driving was not a matter of major concern to the States (Welsh v Wisconsin, supra, p _, n 14, p 2100, n 14). Indeed, the Supreme Court has clearly recognized the compelling State interest in highway safety (supra, p _, pp 2100-2101 [Blackmun, J., concurring]; South Dakota v Neville, 459 US 553, 558-559). Given this State’s strong interest in protecting the public and in preventing the tragic consequences of drunk driving, we conclude that a warrantless home arrest of an intoxicated driver may be made where exigent circumstances exist.
*197Here, the arrest was justified as a continuation of the uninterrupted pursuit of petitioner and a measure designed to prevent the destruction of evidence by timely ascertaining petitioner’s blood alcohol level (see Welsh v Wisconsin, supra, p _, pp 2099-2100; United States v Santana, 427 US 38, 42-43; Schmerber v California, 384 US 757). To ensure an accurate measurement, the chemical test for intoxication must be administered within two hours after the driver has been arrested (Vehicle and Traffic Law, § 1194, subd 1, par [1]; see Schmerber v California, supra, p 770). This fact, coupled with the possibility that a suspect could consume additional alcohol upon arriving at his home, makes immediate action by an arresting officer imperative. We also note that the deputies in the instant case gained peaceful entry into petitioner’s home (see United States v Martinez-Gonzalez, 686 F2d 93, 100). Considering all these factors, we conclude that the arrest was lawful and that the determination to revoke petitioner’s license is supported by substantial evidence in the record.
We have examined petitioner’s remaining contentions and find them unavailing. Even assuming, arguendo, that petitioner has standing to challenge the eligibility requirements for participation in an alcohol and drug rehabilitation program (see 15 NYCRR part 134), we perceive no violation of petitioner’s right to equal protection from the fact that these programs are limited to individuals convicted of a violation of section 1192 of the Vehicle and Traffic Law. The criminal charges against petitioner were dismissed, and thus it would be irrational to place an individual who has neither failed a chemical test nor been convicted of driving while intoxicated in a program to rehabilitate intoxicated drivers. We note that petitioner could have requested respondent Commissioner to direct that his license be restored six months after the revocation (Vehicle and Traffic Law, § 510, subd 2, par e, as relettered by L 1983, ch 892, § 1). Finally, petitioner’s contention with respect to laches is without merit (see Matter of Geary v Commissioner of Motor Vehicles, 92 AD2d 38, affd 59 NY2d 950; Matter of Viger v Passidomo, 103 AD2d 993).
