International initiative to get trial on the move? (4,5)
I believe the answer is:
test drive
'trial on the move?' is the definition.
(test or trial for a moving vehicle)
'international initiative' is the wordplay.
'international' becomes 'test' (I've seen this before).
'initiative' becomes 'drive' (both can mean ambition or resourcefulness).
'test'+'drive'='TEST-DRIVE'
'to get' acts as a link.
(Other definitions for test drive that I've seen before include "Trial run" , "Try out new car" , "Evaluate performance" , "Assess performance" , "Decisive run" .)
