The previtreous dynamics in glass forming monomer, glycerol monoacrylate(GMA), using broadband dielectric spectroscopy (BDS) was tested. Measurementsrevealed the clear dynamic crossover at temperature $T_B = 254$ K and the timescale $\tau(T_B) = 5.4$ ns for the primary (structural) relaxation time and nohallmarks for the crossover for the DC electric conductivity $\sigma_{DC}$.This result was revealed via the derivative-based and distortions-sensitiveanalysis $dln{H_{a}}/d(1/T)$ vs. $1/T$, where $H_a$ is for the apparentactivation energy. Subsequent tests of the fractional Debye-Stokes-Einstenrelation $\sigma_{DC}(\tau_{\alpha})^S = const$ showed that the crossover isassociated with $S = 1$ (for $T>T_B$)->$S = 0.84$ (for $T<T_B$). The crossoveris associated with the emergence of the secondary beta relaxation whichsmoothly develops deeply into the solid amorphous phase below the glasstemperature $T_g$.
