What is the test for a police officer to conduct analysis of a suspect in a traffic collision?

analysis proceeds with various objective observations, information from police reports, if such are available, and consideration of the modes or patterns of operation of certain kinds of lawbreakers. From these data, a trained officer draws inferences and makes deductionsinferences and deductions that might well elude an untrained person." (United States v. Cortez, supra, 449 U.S. at p. 418.)

"The second element contained in the idea that an assessment of the whole picture must yield a particularized suspicion is the concept that the process just described must raise a suspicion that the particular individual being stopped is engaged in wrongdoing." (United States v. Cortez, supra, 449 U.S. at p. 418.)
