Checking car travel round Ulster (10)

I believe the answer is:

monitoring

'checking' is the definition.
('monitor' can be a synonym of 'check')

'car travel round ulster' is the wordplay.
'car travel' becomes 'motoring' (I've seen this before).
'round' means one lot of letters goes inside another.
'ulster' becomes 'ni' (Northern Ireland).
'motoring' placed around 'ni' is 'MONITORING'.

(Another definition for monitoring that I've seen is " Supervisory work".)

I've seen this clue in The Telegraph.
