48-year-old Lisa Long was arrested Monday on suspicion of child endangerment and criminal negligence after police responded to a call Monday in the 2000 block of Gollihar.
Police said an eyewitness reported seeing two children ranging in age from six-to-eight exit the back of a box truck.
A third child was reportedly riding in the passenger seat.
Police determined the children were riding in the truck with no restraints and no ventilation. Uncapped syringes were also found in the back of the vehicle with the children.
The children are now in custody of Child Protective Services. Long was taken to the Nueces County Jail.
