Making Way- Not in Boston

The guy ahead of me has stopped his car in the middle of the single lane road for no apparent reason.
The guy, actually gal, behind me is venting her frustration on the horn.
A long line of cars has already formed

What could be wrong?

I look on one side of the road and then the other.
