    The People of the State of New York, Respondent, v Ralph M., Appellant.
    [640 NYS2d 797]
   Appeal by the defendant from a judgment of the Supreme Court, Queens County (Roman, J.), rendered June 28, 1994, convicting him of criminal possession of a controlled substance in the third degree, upon a jury verdict, and imposing sentence.

Ordered that the judgment is affirmed.

The defendant has not preserved for appellate review his challenges to the admission of testimony by the police witnesses (see, CPL 470.05 [2]; People v Tevaha, 84 NY2d 879; People v Walker, 220 AD2d 469). In any event, we reject the defendant’s contention that he was denied a fair trial by the admission of this testimony. The court admitted properly limited expert testimony regarding the general practices in street-level drug transactions inasmuch as it helped the jury understand the actions of the police that led to the defendant’s arrest (see, People v Tevaha, supra; People v Brown, 218 AD2d 813; People v Kane, 207 AD2d 846, affd 85 NY2d 1024; People v Peoples, 202 AD2d 694).

The defendant’s remaining contentions are either unpreserved for appellate review or without merit. Sullivan, J. P., Copertino, Pizzuto and Florio, JJ., concur.
