Vehicle’s uncontrolled movements: search follows (9)

I believe the answer is:

fishtails

'vehicle's uncontrolled movements' is the definition.
(fishtail can mean a movement made by a vehicle)

'search follows' is the wordplay.
'search' becomes 'fish' (fishing is a kind of searching).
'follows' becomes 'tails' (I've seen this in another clue).
'fish'+'tails'='FISHTAILS'

I've seen this clue in The Times.
