Defendant appealed the decision of the Burrillville Municipal Court sustaining the violation of R.I.G.L. 1956 § 31-14-2 (prima facie limits). The Appeals Panel found that the requirements set forth in State v. Sprague, 322 A.2d 36 (R.I. 1974), were satisfied where the officer testified that the radar unit had been properly calibrated within a reasonable time and that he was trained and experienced in the operation of radar devices, despite the failure to certify three calibration reports and admit them into evidence. Accordingly, the Court affirmed the decision sustaining the charge against the defendant.
