Within seconds, fool gets out of control (5)
I believe the answer is:
skids
'gets out of control' is the definition.
(eg skids in a vehicle)
'within seconds fool' is the wordplay.
'within' indicates putting letters inside.
'seconds' becomes 'ss' (the abbreviation for second twice).
'fool' becomes 'kid' (kidding is a kind of fooling).
'ss' going around 'kid' is 'SKIDS'.
(Other definitions for skids that I've seen before include "From coasts" , "Slides without control" , "Slides sideways" .)
