Bear that's found by side of road (8)
I believe the answer is:
shoulder
This clue is a double definition.
'bear' is the first definition.
(both can mean to carry or take responsibility for)
'that's found by side of road' is the second definition.
(Other definitions for shoulder that I've seen before include "take responsibility?" , "On the side of the road, it might be hard" , "Between the neck and the upper arm (8)" , "Old usher, oddly, is part of the body" , "Top of the arm" .)
