The driver of the truck, 35-year-old Rogelio Diaz-Garcia, has been charged with intoxication manslaughter.
"Iyana was the sweetest, most soft-spoken, hardworking young lady," said her mother, Reta Harris.
Harris-Smith's family said she graduated from Westside High school in 2019. They said she was kind, creative and loved dogs.
"She had such a love for music. She knew the songs that would be the next hit before they became popular," said Reta.
They were planning to celebrate Harris-Smith's birthday in Las Vegas next month.
"This was unnecessary. We were getting ready to celebrate," said Reta.
Harris-Smith's family is pleading people not get behind the wheel if they have been drinking.
"We have to just be safer as a society and do better in Houston," said Reta. "Houston is such a beautiful city and there's no reason, no excuse for our city to have this much drunk driving," said Imani Johnson, Iyana's sister.
"Please reconsider before you drink and drive. Reconsider it. Think about what could happen. You were out drinking and you decided to get behind the wheel, and now my baby is gone," said Reta.
