In 1993, Brualdi and Massey conjectured that every graph can be incidence-colored withΔ+2 colors, where Δ is the maximum degree of a graph. Although this conjecture was solved in the negative by an example in I. Algor and N. Alon (Discrete Math. 75 (1989) 11) it might hold for some special classes of graphs. In this paper, we consider graphs with maximum degree Δ=3 and show that the conjecture holds for cubic Hamiltonian graphs and some other cubic graphs.
