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 the Appeals Panel was not clearly erroneous in holding that the operational efficiency of the radar gun was tested within a reasonable time by an appropriate method, that there was testimony regarding the officer’s training and experience with a radar gun, and that the radar gun was calibrated within a reasonable time. Accordingly, the Court affirmed the decision sustaining the violation against the defendant.
