Passerby Jim Angulo, who recorded the footage, said he initially yelled at the man to get out of the truck. When the driver replied that he was stuck, Angulo ran toward the vehicle.
"I saw 20 people with their cell phones out not doing nothing," he told WSVN-TV. "I said, 'It's on me.'"
Angulo said he and another man intervened to pull the man from the wreckage.
The driver suffered burn injuries to his legs in the fire, according to Angulo, who posted the video on social media with the hashtag #dontjustrecordsavesomeone.
