Defendant appealed the decision of the trial court sustaining the violation of R.I.G.L. 1956 § 31-14-2 (prima facie limits). The defendant introduced paperwork evidence from his GPS indicating that he was not speeding at the time he was stopped by the citing officer. The citing officer testified that defendant was speeding according to his radar, that the unit had been properly calibrated, and that he was trained in the use of radar units in 2005. The Court held that the officer’s testimony satisfied the requirements set forth in State v. Sprague, 322 A.2d 36 (R.I. 1974), that the efficiency of the radar unit be tested within a reasonable amount of time and that the officer testify to his training and experience with a radar unit. Accordingly, the Court affirmed the decision sustaining the charge against the defendant.
