Texas uses electronic billboards to raise awareness and combat human trafficking.
"We're just trying to make sure people will know that there's a national human trafficking hotline that you can call, and if you see something that doesn't look right you may be saving someone's life," Texas Secretary of State Ruth Hughs told KIII-TV.
The billboards going up in Padre Island, which will feature a phone number to call if trafficking is suspected, will be in both English and Spanish.
According to the State Attorney General's Office, there are 234,000 victims of labor trafficking and 79,000 child victims of sex trafficking at any given time.
The Department of Homeland Security defines human trafficking as the use of force, fraud, or coercion to obtain some type of labor or commercial sex act.
The phone number to the National Human Trafficking Hotline is 1-888-373-7888. You can also text "HELP" or "INFO" to 233733.
