We analyze the anomalous quartic gauge boson couplings $WW\gamma\gamma$ and $ZZ\gamma\gamma$, described by dimension-6 effective quartic Lagrangian at the LHC. The sensitivities to anomalous quartic gauge couplings $a_{ 0,c}^{ W,Z}/\Lambda^2$ by examining the two different photon-induced processes $pp\to p\gamma p\to p W\gamma qX$ and $pp\to p\gamma p\to p ZZ qX$ with $W$ and $Z$s decaying leptonically are investigated. We show that $\gamma p$ mode of photon-induced reactions at the LHC are able to probe these couplings to the order of $10^{ -6}$-$10^{ -7}$ GeV$^{ -2}$ at 95 % confidence level with $\sqrt s$ = 14 TeV and for proton-proton luminosities in the range of 30-200 fb$^{ -1}$.
