Opinion of the Court
road's use by smugglers, the temporal proximity between respondent's trip and the agents' shift change, and the use of minivans by smugglers—were not enough to render the stop permissible. Id., at 1251. We granted certiorari to review the decision of the Court of Appeals because of its importance to the enforcement of federal drug and immigration laws. 532 U. S. 1065 (2001).
The Fourth Amendment prohibits "unreasonable searches and seizures" by the Government, and its protections extend to brief investigatory stops of persons or vehicles that fall short of traditional arrest. Terry v. Ohio, 392 U. S. 1, 9 (1968); United States v. Cortez, 449 U. S. 411, 417 (1981).

When discussing how reviewing courts should make reasonable-suspicion determinations, we have said repeatedly that they must look at the "totality of the circumstances" of each case to see whether the detaining officer has a "particularized and objective basis" for suspecting legal wrongdoing. See, e. g., id., at 417-418. This process allows officers to draw on their own experience and specialized training to make inferences from and deductions about the cumulative information available to them that "might well elude an untrained person." Id., at 418. See also Ornelas v. United States, 517 U. S. 690, 699 (1996) (reviewing court must give "due weight" to factual inferences drawn by resi-
