Apparently a train was about to pull out and, as he approached, the driver blew the whistle for departure.

Behind them, the driver of a green Datsun blew his horn.

The driver blew his horn in greeting and jumped out.

The driver blew on his flight horn, and its call rang through the evening air.

The driver blew the horn and then jumped out.

As it passed me, the driver grinned happily and blew his horn.

The drivers hardly ever blow their horns or recklessly gun past us.

The driver flipped me the bird and blew his horn.

Any moment now some driver would blow his horn at a kid running across the street and he would wake up.

As if to contradict him, the driver blew another long blast.
