Defendant appealed the decision of the Appeals Panel sustaining the violation of R.I.G.L. 1956 § 31-14-2 (prima facie limits). The Court held that there was substantial, probative, and reliable evidence to sustain the charge against the defendant because the officer testified that he had been trained to use a radar unit and that the radar unit had been calibrated. Since the decision of the trial judge was not clearly erroneous, the Court affirmed the decision sustaining the charge against the defendant.
