Panzer II in Front of a Road Block

This Panzerkampfwagen II approaches a railroad track where locomotives and civilian vehicles have been placed as road blocks, 1940. Note the open hatches on the rear deck, which were used to provide access for engine components. The man exposed outside the vehicle would seem to indicate the lack of a direct threat to the panzer. There are no easily-visible markings to be seen from this angle, although there appears to be a rhomboid plate just above the engine exhaust muffler.
