Tool gets inexperienced driver out of difficulty (3)
I believe the answer is:
hoe
'tool' is the definition.
(I know that hoe is a type of tool)
'inexperienced driver out of difficulty' is the wordplay.
'inexperienced driver' becomes 'l' (a learner driver's car carries L-plates).
'out of' is a deletion indicator.
'difficulty' becomes 'hole' (hole can mean a difficult situation).
'hole' with 'l' taken away is 'HOE'.
'gets' acts as a link.
(Other definitions for hoe that I've seen before include "Garden tool with a flat blade" , "Gardening tool" , "Plymouth - -" , "Tool for loosening soil and scraping up weeds" , "Weed" .)
