The lead vehicle in a line of cars stopped quickly, forcing the three cars behind it to also brake abruptly, Rose said.

The streetcar was unable to stop in time and struck the rear car from behind, he said.

Rose had initially said it was the streetcar that had been rear-ended by another vehicle.

One driver was taken to the hospital, but Rose did not know his condition, nor which car he was in.
