We consider bimodal linear systems consisting of two linear dynamics acting on each side of a
given hyperplane, assuming continuity along the separating hyperplane. We prove that the study
of controllability can be reduced to the unobservable case, and for these ones we obtain a simple
explicit characterization of controllability for dimensions 2 and 3, as well as some partial criteria for
