SAN DIEGO — A 20-year-old man was hit and killed after getting out his car on Interstate 5 early Wednesday, according to authorities.

California Highway Patrol closed the transition ramp from I-5 south to eastbound state Route 94 for the investigation, which began around 6 a.m. Officers said in a news release that the man, a Las Vegas resident, was walking on the freeway when he was hit.

“It appears he was having some type of disagreement with the person he was in the car with,” CHP Sgt. Hope Maxson told Onscene.TV at the crash site. “And he did get out of the car and he was struck by a vehicle pretty instantly.”

A woman and 2-year-old were in the car the man got out of, according to CHP.

“There isn’t a way to say how terrible somebody would be doing, this type of incident happening right in front of you. How do you explain that to a 2-year-old?” Maxson said when asked how the 2-year-old was doing.

The driver who hit the 20-year-old victim was cooperating with police and CHP does not believe the motorist was under the influence of drugs or alcohol, the news release said.

Toxicology results for the man killed are pending, according to CHP.
