  We study the Goos-H\"anchen (GH) shifts for transmitted Dirac fermions in
gapped graphene through a single barrier structure having a time periodic
oscillating component. Our analysis shows that the GH shifts in transmission
for central band $l=0$ and two first sidebands $l=\pm1$ change sign at the
Dirac points $E=V+l\hbar\omega$. In particular the GH shifts inbtransmission
exhibit enhanced peaks at each bound state associated with the single barrier
when the incident angle is less than the critical angle associated with total
reflection. Klein tunneling, reflected by perfect transmission at normal
incidence, is also preserved in the presence of an oscillating barrier.
