Mr. Justice Rehnquist
delivered the opinion of the Court.
Petitioner James Gustafson was convicted in a Florida trial court for unlawful possession of marihuana. At his trial the State introduced into evidence marihuana which had been seized from him during a search incident to his arrest on a charge of driving without possession of an operator’s license. The District Court of Appeal of Florida, Fourth District, reversed petitioner’s conviction, holding that the search which had led to the discovery of the marihuana was unreasonable under the Fourth and Fourteenth Amendments. 243 So. 2d 615 (1971). The Supreme Court of Florida in turn reversed that decision, 258 So. 2d 1 (1972), and petitioner sought certiorari in this Court. We granted certiorari, 410 U. S. 982 (1073), and set the case for argument with No. 72-936, United States v. Robinson, also decided today, ante, p. 218. For the reasons set forth below, we affirm the judgment of the Supreme Court of Florida.
At approximately 2 a. m., on January 12, 1969, Lieutenant Paul R. Smith, a uniformed municipal police officer of Eau Gallie, Florida, was on a routine patrol in an unmarked squad car when he observed a 1953 white Cadillac, bearing New York license plates, driving south through the town. Smith observed the automobile weave across the center line and back to the right side of the road “three or four” times. Smith testified that he observed the two occupants of the Cadillac look back; after they apparently saw the squad car, the car drove across the highway and behind a grocery store, and then headed south on another city street.
At that point Smith turned on his flashing light and ordered the Cadillac over to the side of the road. After stopping the vehicle, Smith asked petitioner, the driver, to produce his operator’s license. Petitioner informed Smith that he was a student and that he had left his operator’s license in his dormitory room in the neighboring city of Melbourne, Florida. Petitioner was then placed under arrest for failure to have his vehicle operator’s license in his possession. It was conceded by the parties below and in this Court that the officer had probable cause to arrest upon learning that petitioner did not have his license in his possession, and that he took petitioner into custody in order to transport him to the stationhouse for further inquiry.
Smith then proceeded to search the petitioner’s person. Smith testified that he patted down the clothing of the petitioner, “outside and inside, I checked the belt, the shirt pockets and all around the belt, completely around inside.” Upon completing his patdown, he testified, he placed his hand into the left front coat pocket of the coat petitioner was wearing. From that pocket he extracted a “long chain” and a Benson and Hedges cigarette box. Smith testified that he then “opened [the cigarette box] and it appeared there were marihuana cigarettes in the box. I had been shown this in training at the police department and these appeared to be marihuana to me.”

Petitioner urges that there could be no evidentiary-purpose for the search conducted by Smith, and therefore the authority to search for weapons incident to a lawful arrest is controlled by the standards laid down in Terry v. Ohio, 392 U. S. 1 (1968). Petitioner contends that this case is different from United States v. Robinson, ante, p. 218, in that petitioner had experienced no previous encounters with the officer in this case, and the offense for which he was arrested was “benign or trivial in nature,” carrying with it no mandatory minimum sentence as did the offense for which Robinson was arrested. Petitioner points out that here, unlike Robinson, there were no police regulations which required the officer to take petitioner into custody, nor were there police department policies requiring full-scale body searches upon arrest in the field. Petitioner also points to the fact that here, as in Robinson, the officer expressed no fear for his own well-being or for that of others in dealing with the petitioner.
We have held today in United States v. Robinson that “[i]t is the fact of the lawful arrest which establishes the authority to search, and ... in the case of a lawful custodial arrest a full search of the person is not only an exception to the warrant requirement of the Fourth Amendment, but is also a 'reasonable’ search under that Amendment.” Ante, at 235. Our decision in Robinson indicates that the limitations placed by Terry v. Ohio, supra, on protective searches conducted in an investigatory stop situation based on less than probable cause are not to be carried over to searches made incident to lawful custodial arrests. We stated in Robinson:
“The justification or reason for the authority to search incident to a lawful arrest rests quite as much on the need to disarm the suspect in order to take him into custody as it does on the need to preserve evidence on his person for later use at trial. Agnello v. United States, 269 U. S. 20 (1925); Abel v. United States, 362 U. S. 217 (1960). The standards traditionally governing a search incident to lawful arrest are not, therefore, commuted to the stricter Terry standards by the absence of probable fruits or further evidence of the particular crime for which the arrest is made.”. Ante, at 234.
Neither Chimel v. California, 395 U. S. 752 (1969), nor Peters v. New York, 392 U. S. 40 (1968), relied upon by petitioner, purported to limit the traditional authority of the arresting officer to conduct a full search of the person of an arrestee incident to a lawful custodial arrest. United States v. Robinson, ante, at 225-226, 228-229. Indeed, as our decision in Robinson indicates, not only has this been established Fourth Amendment law since the decision in Weeks v. United States, 232 U. S. 383 (1914), but it was also the rule both at common law and in the early development of American law. United States v. Robinson, ante, at 230-233.
Though the officer here was not required to take the petitioner into custody by police regulations as he was in Robinson, and there did not exist a departmental policy establishing the conditions under which a full-scale body search should be conducted, we do not find these differences determinative of the constitutional issue. Id., at 223 n. 2. It is sufficient that the officer had probable cause to arrest the petitioner and that he lawfully effectuated the arrest and placed the petitioner in custody. In addition, as our decision in Robinson makes clear, the arguable absence of “evidentiary” purpose for a search incident to a lawful arrest is not controlling. Id., at 233. “The authority to search the person incident to a lawful custodial arrest, while based upon the need to disarm and to discover evidence, does not depend on what a court may later decide was the probability in a particular arrest situation that weapons or evidence would in fact be found upon the person of the suspect.” Id., at 235.
II
We hold, therefore, that upon arresting petitioner for the offense of driving his automobile without possession of a valid operator’s license, and taking him into custody, Smith was entitled to make a full search of petitioner’s person incident to that lawful arrest. Since it is the fact of custodial arrest which gives rise to the authority to search, it is of no moment that Smith did not indicate any subjective fear of the petitioner or that he did not himself suspect that the petitioner was armed. Having in the course of his lawful search come upon the box of cigarettes, Smith was entitled to inspect it; and when his inspection revealed the homemade cigarettes which he believed to contain an unlawful substance, he was entitled to seize them as “fruits, instrumentalities, or contraband” probative of criminal conduct. Harris v. United States, 331 U. S. 145, 154-155 (1947); Warden v. Hayden, 387 U. S. 294, 299, 307 (1967); Adams v. Williams, 407 U. S. 143, 149 (1972); United States v. Robinson, ante, at 236. The judgment of the Supreme Court of Florida is therefore
Affirmed.

Brief for Petitioner 9.
Upon placing petitioner under arrest for driving without possession of an operator’s license and after removing the chain and the cigarette box from petitioner’s clothing, Smith told the assisting officer on the scene to check the other passenger of the Cadillac to see if he had an operator's permit so that he could drive the car tO the station. Smith then put petitioner in the back seat of the squad car. Smith then opened the cigarette box and observed the rolled cigarettes he believed to be marihuana. He then told the other officer to place the other passenger in the squad car so that he could also be transported to the station, for the purpose of investigation. The passenger was frisked by the other officer and placed in the squad car; no charges were placed against the passenger. In addition to the marihuana conviction which we here review, petitioner was charged with driving without possession of an operator’s license; that charge was dropped when petitioner produced a valid operator’s license at a later date.
Smith testified that he wrote about eight to 10 traffic citations per week, and that about three or four out of every 10 persons he arrested for the offense of driving without a license were taken into custody to the police station. Smith indicated that an offender is more likely to be taken into custody if he does not reside in the city of Eau Gallie. Finally, Smith testified that after making a custodial arrest, he always searches the arrestee before placing him into the patrol car.
The State of Florida argues in this Court that there was an evidentiary purpose for the search of petitioner. It is contended that Smith’s observation of the erratic motions of the car that petitioner was driving created a reasonable suspicion that the petitioner may have been under the influence of some intoxicant. Upon confronting petitioner after stopping the ear, Smith indicated that he noticed that the petitioner’s eyes were “bleary.” The State argues that the officer had probable cause to arrest the petitioner for driving while intoxicated, and that Smith thought Gustafson was intoxicated when he confronted him. Since Smith did not detect an odor of alcohol during that confrontation, the State argues it was reasonable for the officer to search the petitioner’s person for drugs that may have been the cause of the suspected intoxication. Florida makes it a criminal offense to drive while intoxicated not only by alcohol, but also by unlawful drugs. Fla. Stat. Ann. §317.201 (1968).
What follows is an opinion from the Supreme Court of the United States. Your task is to determine whether the decision of the court whose decision the Supreme Court reviewed was itself liberal or conservative. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. The lower court's decision direction is unspecifiable if the manner in which the Supreme Court took jurisdiction is original or certification; or if the direction of the Supreme Court's decision is unspecifiable and the main issue pertains to private law or interstate relations
