The known theory on the one-side exact boundary controllability for first order quasilinear hyperbolic systems requires that the unknown variables are suitably coupled or satisfy the Group Property in boundary conditions at the non-control side (see [5],[10]). In this paper we illustrate, with an inspiring example, that the one-side exact boundary controllability can still be realized by means of a suitable coupling among the unknown variables in the quasilinear hyperbolic system itself instead of in boundary conditions.
