Residents in Oklahoma who were commuting home last week when the storm gained strength became vulnerable on the highway. Some may have planned ahead to escape the tornado, but regardless they were stuck on the road and risked becoming the victim of flash flooding.
CNN's Chad Myers says a car is never a safe place to be during a twister. "When a tornado gets done with a car, there's no place left for you in it. The entire thing is smashed to bits," he tells Anderson Cooper.
The Oklahoma Office of the Chief Medical Examiner confirms at least 18 people died on Friday. Three men who lost their lives were storm chasers Tim Samaras, Paul Samaras and Carl Young. Myers emphasizes that Tim was not a daredevil and not carelessly on the road, but a scientist collecting data to better help the government.
For people who do find themselves in traffic during a tornado, Myers suggests seeking shelter as soon as possible. "Drive up to a store, drive up to somebody's house, and get in that house, not the ditch, because you can get hit by things getting to the ditch."
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
