Socialist Worker sales campaign? Car from abroad appears? (4-4,5)
I believe the answer is:
left-hand drive
'car from abroad appears?' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'socialist worker sales campaign?' is the wordplay.
'socialist' becomes 'left' (associated in meaning).
'worker' becomes 'hand' (hand is a kind of worker).
'sales campaign?' becomes 'drive' (sales campaign is a kind of drive).
'left'+'hand'+'drive'='LEFT-HAND DRIVE'
Can you help me to learn more?
(Other definitions for left-hand drive that I've seen before include "Not designed for driving in Britain" , "Like continental estate, perhaps" , "(Car) designed for continental roads?" , "Feature of a Continental car?" .)
