What is the test for probable cause for a search of a van in a traffic collision?

2. The officers had probable cause to search the van based on "the totality of the circumstances known to [them] at the time of the search." United States v. Ped, 943 F.3d 427, 431 (9th Cir. 2019) (cleaned up). Probable cause exists "where the known facts and circumstances are sufficient to warrant a man of reasonable prudence in the belief that contraband or evidence of a crime will be found." Ornelas v. United States, 517 U.S. 690, 696 (1996) (citations omitted). Here, the district court's finding that the officers smelled burnt marijuana, combined with other factors, supports probable cause for the vehicle search.
