I don't think the verb "to veer" is the best one the author could have used in this situation. But, without my crystal ball that provides me with the context of your question, I can only guess that he meant to say "turn" right off of Udall instead of veer right.
"Also what does Udall mean?"
My crystal ball is showing me something about the US State of Arizona - I think it's the city of Phoenix. I see a street named after a local politician: Morris K Udall.
Ahh - the vision has gone away.
