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 State v. Sprague, 113 R.I. 351, 322 A.2d 23 (1974) did not create a rule that an officer must have a certain amount of experience with radar units.  Thus, the officer’s failure to testify to his experience with radar units did not change the result of the case, because the other two elements of Sprague were met. Accordingly, the Court sustained the violation against the defendant.
