keep left

I'm a little stuck... Click here to teach me more about this clue!

'direction for traffic' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'remaining behind castle' is the wordplay.
'remaining' becomes 'left' (synonyms).
'behind' means one lot of letters go next to another.
'castle' becomes 'keep' (I've seen this in other clues).
'left' after 'keep' is 'KEEP LEFT'.

Can you help me to learn more?
