Lone buck roaming Germany without obstruction (9)
I believe the answer is:
unblocked
'without obstruction' is the definition.
I can't judge whether this defines the answer.
'lone buck roaming germany' is the wordplay.
'roaming' indicates anagramming the letters.
'germany' becomes 'd' (vehicle registration code for Deutschland).
'lone'+'buck'='lonebuck'
'lonebuck' with letters rearranged gives 'unblocke'.
'unblocke'+'d'='UNBLOCKED'
Can you help me to learn more?
(Another definition for unblocked that I've seen is " Freed from obstruction".)
