Vehicle to travel, bringing load (5)
I believe the answer is:
cargo
'load' is the definition.
('cargo' can be a synonym of 'load')
'vehicle to travel' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'to travel' becomes 'go' ('go' can be a synonym of 'travel').
'car'+'go'='CARGO'
'bringing' is the link.
(Other definitions for cargo that I've seen before include "Payload" , "Goods being transported" , "Goods carried on ship or plane" , "Goods in transit" , "Ship's freight" .)
