Poor driver - I need plug changing (15)
I believe the answer is:
underprivileged
'poor' is the definition.
('underprivileged' is associated in meaning with 'poor')
'driver i need plug changing' is the wordplay.
'changing' indicates an anagram.
'driver'+'i'+'need'+'plug'='driverineedplug'
'driverineedplug' with letters rearranged gives 'UNDERPRIVILEGED'.
(Other definitions for underprivileged that I've seen before include "In need" , "Poor" , "no advantages" .)
