Two children were among three people killed Wednesday morning in a car crash in Dallas, authorities said.

According to the Dallas Police Department, two vehicles were involved in the crash around 8 a.m. on East Clarendon Drive and North Street, less than one mile from the Dallas Zoo.

Video of the scene from CBS News Texas Chopper showed a white Toyota SUV severely damaged with numerous airbags deployed. The other vehicle that appeared to be involved was a heavy-duty pickup truck.

Responding paramedics took four children and two adults to the hospital. Dallas police said "one adult, one juvenile and one child" died. They did not specify the conditions of the other victims.

Dallas police have not yet identified anyone involved or said what led up to the crash. The investigation is ongoing. 

Surveillance captured truck seconds before crash 

" [I was] at a friend's house playing the game, and I heard a loud noise. So when I heard it, I just came outside to see what was going on," said Richard James, who was at the scene. 

Security camera video from a nearby store showed the heavy-duty truck driving west on Clarendon Road seconds before it crashed into the SUV. 

Survivors and witnesses surrounded the wreckage. 

"I just think this road right here was just too slick and you know, they lost control and hit into this truck right here," said James. 

Residents say the roadway is dangerous 

The deadly accident happened in a shadowed area and has neighborhood residents urging the city to make it safer.  

Dwayne Conger said he drives down through the area of the crash often, and there are blind curves with low-hanging trees. He said it needs lower speed limits. 

"I think they need to do something. The city needs to do something with this curve right here," Conger said. "Flashing warning lights, deep curve, things that they have in parts of the city for situations like this. And I think they really need it, because if you look, you come around, you can't see coming around the curve right there."
