Permission to proceed -- there's headroom enough (9)

Ross

I believe the answer is:

clearance

This clue is a double definition.

'permission to proceed' is the first definition.
(I've seen this before)

'headroom enough' is the second definition.
(as in headroom for a vehicle)

'there's' acts as a link.

(Other definitions for clearance that I've seen before include "Eviction from lands" , "Official permission (for an action)" , "Headroom" , "Vacation" , "eviction from land" .)

I've seen this clue in The Telegraph.
