Thanks to high gamma-gamma center-of-mass energies, the exclusive two-photon production of W or Z bosons pairs at LHC will offer large and direct sensitivity to the anomalous quartic gauge couplings. An initial analysis has been performed assuming double lepton final states and generic acceptance cuts. Simulation of a simple counting experiment has shown for the integrated luminosity of 10fb^(-1) at least 4000 times larger sensitivity to the genuine quartic couplings than limits obtained at LEP. Finally, using a differential distributions of final state leptons we show a potential for further improvements of the sensitivities.
