I believe the answer is:

steer

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

'guidance' is the definition.
(I know that steer is a type of guidance)

I don't understand the remainder of the clue.

(Other definitions for steer that I've seen before include "Direct; bullock" , "Guide; bullock" , "Manoeuvre" , "The animal to direct" , "Exercise control" .)

I've seen this clue in The Sun.
