Video shows car falling from Dallas High 4

Now seeing the shocking video of a car flying off U.S. 75 near the High Five Interchange in Dallas. And we do want to warn you, this video may be disturbing to some viewers. A traffic camera captured the vehicle flipping off the interstate and falling into a ditch below, killing the 60-year-old driver inside. Fox 4's Lori Brown is live in Dallas with this story. Lori. Aiden, we talked with a civil engineer about the High Five interchange here in Dallas and if there need to be better barriers to prevent a car from flipping over the side. This is the horrific moment a car plunged over US 75 northbound near Midpark Road in the High Five interchange. It happened Monday just after 4 p.m. A pickup and sedan pulled over and three men looked over the barrier at the aftermath. Sky 4 later captured these images of police responding to the wreckage. Dallas Fire Rescue pronounced the driver dead at the scene. Dallas police say their preliminary investigation determined that before the car went over the Before the overpass, there was a crash involving a second car. Engineering professor Dr. Nur Yazdani at UT Arlington says barriers are built to withstand drivers traveling at posted speeds. This is very common on Texas highways. I see we see a lot of them every day. They're very stable. They're connected to the bridge, rigidly connected. And you know, they have been crash tested. The Dallas Medical Examiner identified the driver as Juan Hernandez Paez Sr., he was 60 years old. And it appears from the video that the barrier did not break, but rather the car went over it entirely. To me, it looks like it went over the barrier. It didn't hit the barrier because I didn't see any debris flying or something like that. In the case of the high five interchange, barriers could be taller, but it would be expensive. We don't design for all kinds of of crash because of benefit cost you know if you have to make it very rigid They're taking all kind of impact. It's gonna cost a lot of money, like my own home for a tornado. If I design for a tornado, I have to spend much more money. But if I design for a hurricane at a lower speed, it's much more cost-benefit-wise feasible. The driver of the second car involved in the crash remained at the scene. No arrests were made. Dr. Yazdani says it is fortunate more people were not killed. Suddenly, if a vehicle falls on a lower level on another highway, then you have a bunch of traffic there. That could be devastating. Does police have not said what caused the driver to lose control, what speed he was believed to be traveling, or if there is any indication yet if drugs or alcohol were involved? Eden? Lori, thank you so much.
