Video footage of a double school bus collision in Copiague, which injured three, shows one of the buses failing to yield to a stop sign just before the crash.
A Suffolk police spokesman said Wednesday they could not comment on the video, and neither bus driver has been charged.
The crash happened about 3:15 p.m. Tuesday when a school bus driving west on Mazzini Avenue -- which has stop signs in both directions at its intersection with Molloy Street -- collided with a small school bus, which was southbound on Molloy and overturned.
Both bus drivers, whom police have not identified, and a girl who was a passenger on the smaller bus, were treated at the hospital for minor injuries. The other bus had no passengers.
Sheyla Hernandez, 19, heard the crash, called 911 and found that her family's day care center's surveillance camera had captured the crash. Her father, Oscar Hernandez, 45, said people speed in the area and the stop sign that greets drivers westbound on Mazzini is slightly obscured by a tree.
"Nobody can see it," said Hernandez. "If you're not from the area, you easily blow it."
Miguel Lopez, who lives nearby, immediately thought of his 11 grandchildren when he saw the overturned bus.
"I saw a lady panicking. She was screaming, 'There's a baby in there!' " Lopez said Wednesday. He said he opened the back door of the bus and carried out the only passenger, a young girl, who he said was on the floor, crying and had a large gash on her head.
"I just jumped in there and got the kid," said Lopez, 57.
A spokesman for Educational Bus Transportation, the Copiague company that owns both buses, could not be reached Wednesday. On Tuesday the company said it was investigating the crash but had ruled out drugs or alcohol as a factor.
