If he hadn't run the light she might have - there's nothing certain
about it.

It wouldn't matter (to him) if she had "run a red light" (she didn't, as
far as any of us know). That's because they were travelling towards a
common point from two different directions.

He'd have been safe if he'd stopped for the red light as he was obliged
to. But of course, he knew better - or thought he did.
