As a result of a warrantless search contraband was seized from an automobile in which the defendants were riding. After a hearing, a judge of a District Court allowed the defendants’ motion to suppress the evidence. The Commonwealth has taken an appeal. Mass.R.Crim.P. 15(a)(2), 378 Mass. 882 (1979).
The determination of the weight and credibility of the testimony is the function and responsibility of the motion judge, and the subsidiary findings of fact made by him in support of the allowance of a motion to suppress “will be accepted by an appellate court absent clear error.” Commonwealth v. Jones, 375 Mass. 349, 354 (1978). See Commonwealth v. Moon, 380 Mass. 751, 755-756 (1980). We find no such error here.
This case is controlled in all material respects by Commonwealth v. Loughlin, 385 Mass. 60, 62 (1982). See also Commonwealth v. Ferrara, 376 Mass. 502, 505 (1978). The defendants properly were stopped for speeding. The State trooper asked the driver for his license and registration. Both documents were produced, and found to be in order. The trooper then ordered the defendants (i.e., the driver and passenger) to “exit the motor vehicle.”2 Our analysis may stop here,3 as the judge found “[tjhat actions of [the driver], in producing the license and registration were appropriate *968under the circumstances and that he did nothing to cause [the trooper] to be alarmed.”4 That finding has sufficient support in the evidence.

The motion judge warrantably could have concluded that “the police procedure, early on, was not merely for the protection of the officer during the questioning of the two men, but was clearly a search for evidence.” Commonwealth v. Loughlin, 385 Mass. at 65 (Hennessey, C.J., concurring). As in Loughlin and Ferrara, after verification of the driver’s license and registration, “no reason appears why [the defendants] should not have been permitted to continue on their way.” Commonwealth v. Loughlin, 385 Mass. at 62, quoting from Commonwealth v. Ferrara, 376 Mass. at 505. In light of what we already have said, we add that likewise “the record [here] suggests no purpose in ordering [the] occupants out of the car other than ... to make an illegal search.” Commonwealth v. Ferrara, 376 Mass. at 505.
The case is unlike the recent Supreme Judicial Court decision in Commonwealth v. Sumerlin, 393 Mass. 127, 131 (1984), where, the court concluded that “the officer’s decision to open the right front door of the automobile and pat down the colored bag for weapons was a reasonable, protective search” (emphasis supplied). This case does not involve, nor did the judge find, circumstances which would have warranted a protective search. Neither from the findings nor from the evidence can it fairly be concluded that the trooper possessed a reasonable belief which “reasonably warranted] the officer in believing that the suspect [was] dangerous and . . . [might] gain immediate control of weapons.” Commonwealth v. Sumerlin, 393 Mass. at 129. Compare Commonwealth v. Silva, 366 Mass. 402, 410 (1974) (clearly a search for evidence rather than a protective search for weapons), with Commonwealth v. Almeida, 373 Mass. 266, 272 (1977) (search must be confined to the area from which the suspect might gain possession of a weapon).
Order allowing motion to suppress affirmed.
