I cannot read the top left hand bit but it would appear likely other responders are right. Otherwise:- "...having passed a test/examination is qualified/allowed to drive a motor vehicle powered by an internal combustion engine in the classes 2 & 3 (?). Issued at ???/Oder (this must have been somewhere near the Oder River, could be in Poland nowadays) on 31 March (?), 1943". Agree the name looks like Heinrich Koch - "personal signature of the holder". Hope this helps.
