Defendant appealed the decision of the trial court sustaining the violation of R.I.G.L. 1956 § 31-17-6 (yielding to emergency vehicles). The defendant claimed that the trial judge was clearly erroneous in crediting the officer’s testimony over his.  However, the Court held that only the finder of fact may assess the credibility of the witnesses. Accordingly, the Court affirmed the decision of the trial court sustaining the charge against the defendant.
