Dressed and ready to roll? (2,4)
I believe the answer is:
in gear
'ready to roll?' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for in gear that I've seen before include "Having shifted" , "Ready to drive off" , "ready to go?" , "like moving heaps?" , "Performing effectively" .)
