Traffic was brought to a standstill.

What took you so long?

There was an accident on the freeway, and traffic was bumper to bumper.

Oh, yeah, I just learned from the news on the radio that there was a serious accident involving a truck.

That's right. Traffic was brought to a standstill.

Anyway, thank Heaven that you arrived safe and sound. But, we'd better get going. We're running a little bit late.
