Reyna was discussing a highway accident that could be seen on the screen behind her. As she turned away to wrap up her report, a car swerved and crashed into an SUV, which in turn hit the fire truck that was on the scene for the first accident. “So, yeah, it looks like that one’s going to clear up,” Reyna said.
As Jalopnik notes, Reyna was likely in front of a green screen and may not have been able to see what was happening on the screen behind her. She referenced it during her next traffic report, saying, “It is very rare that we catch an accident live on camera. Can’t believe I just missed it on the last one!” [h/t Jalopnik]
