The Fayette County Sheriff's Office says a deputy and a Texas trooper on Thursday pursued the SUV on Interstate 10 near Flatonia, about 80 miles east of San Antonio. Sheriff Keith Korenek says the driver refused to stop until the SUV ran out of roadway atop a hill.
Flatonia police helped arrest the dozen individuals who tried to run.
Investigators detained the driver on human trafficking and evading arrest charges. The other 11 people were turned over to federal immigration agents in the Houston area.
Authorities did not immediately provide additional information on the immigrants or say a possible destination.
