Examination taken on the way (7,4)
I believe the answer is:
driving test
'examination' is the definition.
(I know that driving test is a type of examination)
'on the way' is the wordplay.
I cannot really see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'way' could be 'st' (abbreviation for street) and 'st' is found within the answer.
This explanation may well be incorrect...
'taken' acts as a link.
Can you help me to learn more?
(Another definition for driving test that I've seen is " assessment of learner".)
