The authors have found a formula involving \(q\)-binomial coefficients for counting pairs of nonintersecting lattice paths which have a prescribed number of weighted turns. The formula is a \(q\)-analogue of a variant of the formula given by \textit{G. Kreweras} and \textit{Y. Poupard} [Eur. J. Comb. 7, 141-149 (1988; Zbl 0647.05007)].
