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 officer’s testimony that the radar unit was calibrated in “stationary” and “moving” modes, and that the unit automatically calibrates itself in “moving” mode was sufficient evidence that the unit was calibrated properly. Accordingly, the Court affirmed the decision of the trial judge sustaining the violation against the defendant.
