What is the current state of the law on the right to search a vehicle without a warrant?

In Chambers v. Maroney, supra, the court pointed out that given probable cause to believe that the vehicle contained articles which the officers were entitled to seize, '. . . if an effective search is to be made at any time, either the search must be made immediately without a warrant or the car itself must be seized and held without a warrant for whatever period is necessary to obtain a warrant for the search.' (399 U.S. at p. 51, fn. omitted, 90 S.Ct. p. 1981.) The court resolved this dilemma as follows: 'For constitutional purposes, we see no difference between on the one hand seizing and holding a car before presenting the probable cause issue to a magistrate and on the other hand carrying out an immediate search without a warrant. Given probable cause to search, either course is reasonable under the Fourth Amendment.' (Id., at p. 52, 90 S.Ct. p. 1981.)
