Captured on video, Trejo, who was wearing a white tank top and rocking a Trejo's Taco hat from his collection of Mexican restaurants in Los Angeles, said that he just so happened to be in the Sylmar area in Southern California when two cars crashed into each other near the intersection of Hubbard Street and Jackman Avenue.
Three people were taken to a hospital, none with life-threatening injuries, the station reported.
Trejo crawled into the wreckage but couldn't unbuckle the auto seat. The cause of the accident remains under investigation. Jackson crawled in on one side of the wreck to unbuckle the boy from his auto seat, and Trejo pulled the child out from the other side.
According to Trejo, "The only thing that saved that little kid was his auto seat".
A reporter from ABC7 said afterward that Trejo distracted the boy until his grandmother was okay.
He said he works with special-needs children so he knew how to keep the little boy calm.
"He was panicked, and I said, 'OK, we have to use our superpowers, ' and so he screamed, 'Superpowers!' and we started yelling, 'Superpowers, '" Trejo recounted. He said "muscles". We got kind of a bond.
Trejo advised motorists to "pay attention" to the road.
Danny, who has appeared in Breaking Bad and in films including Con Air, Desperado and Heat, said that his fortunes in life have been a result of him paying things forward.
'Everything good that has happened to me has happened as a direct result of helping someone else - everything, ' he said.
The 75-year-old Trejo, an LA native, is best known for playing the character Machete in the Spy Kids series, and later in the far more grown up films Grindhouse, Machete, and Machete Kills.
