Caught sailor in front of lorry (3)
I believe the answer is:
cab
'front of lorry' is the definition.
(driver's compartment on a lorry)
'caught sailor' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'sailor' becomes 'ab' (abbreviation for able seaman).
'c'+'ab'='CAB'
'in' acts as a link.
(Other definitions for cab that I've seen before include "Hackney" , "'The authority collects money made from crime, initially (3)'" , "Hired car" , "Driving compartment" , "Transport" .)
