To Laurie, this vehicle is sound (5)
I believe the answer is:
lorry
'to laurie this vehicle is sound' is the definition.
'lorry' can be an answer for 'vehicle' (lorry is a kind of vehicle). I'm not sure about the rest of the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for lorry that I've seen before include "Large motor vehicle for transporting goods" , "Large truck" , "Transport vehicle" , "From which stolen goods fall?" , "Heavy goods vehicle" .)
