What rider uses to navigate traffic obstructions (10)
I believe the answer is:
handlebars
'what rider uses' is the definition.
I can't tell whether this defines the answer.
'navigate traffic obstructions' is the wordplay.
'navigate traffic' becomes 'handle' (I can't justify this - if you can you should believe this answer much more).
'obstructions' becomes 'bars' (bar is a kind of obstruction).
'handle'+'bars'='HANDLEBARS'
'to' acts as a link.
Can you help me to learn more?
(Another definition for handlebars that I've seen is " Part of bike".)
