Law enforcement may stop and search a vehicle without a warrant if there is probable cause based on a totality of circumstances.
Professor Notes

In Brinegar v. United States, the Supreme Court addressed the issue of whether law enforcement officers had probable cause to stop and search a vehicle without a warrant under the Fourth Amendment. This case is pivotal in understanding the nuances of probable cause, emphasizing that officers can act on reasonable suspicions based on totality of circumstances, including a person's history of illegal activities. The Court highlighted the importance of balancing individual privacy rights with the necessity for effective law enforcement in drug and alcohol smuggling contexts.

Furthermore, the Court established that probable cause does not require certainty or evidence beyond a reasonable doubt; rather, it requires a fair probability that contraband or evidence of a crime will be found in the place to be searched. This case also serves as a significant reference point for discussions on pretextual stops and the implications of law enforcement's discretion in applying probable cause standards.
