Defendant appealed the decision of the Appeals Panel sustaining the violations of R.I.G.L. § 31-27-2.1 (refusal to submit to a chemical test), R.I.G.L. 1956 § 31-15-1 (right half of road), and R.I.G.L. 1956 § 31-17-6 (yielding to emergency vehicles). Defendant argued that the arresting officer was not credible because there were inconsistencies in his testimony and he could not remember the name of the Notary Public who notarized his affidavit. However, the Court held the 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.
