We reconsider the single production of the doubly charged Higgs bosons Delta_R^{ ++} and Delta_L^{ ++} at the LHC and TEVATRON in the framework of the left-right symmetric model and the Higgs triplet model. We show that in the left-right symmetric model the production of Delta_R^{ ++} by Drell-Yan process via W_R exchange may give the dominant contribution. The same channel for the production of Delta_L^{ ++} in the Higgs triplet model is insignificant.
