While riding up the inside of a truck is a prety dumb thing to do truckers
arn't immune from forgetting to indicate.

It was already completely over the white give way line turning into the
first exit.

AND

If it was going straight on, it would not be required to indicate,
would have been in the same lane and the trailer would have followed
the same path.
