It happened just before 2:30pm at Suds Car Wash in the 4200 block of West Davis near Loop 336.
According to Conroe police, Juana Gonzalez was there with her family. An attendant had prewashed a diesel four-wheel-drive pickup truck and driven it onto the conveyor mechanism.
A man saw the vehicle leaving the conveyor at a greater than normal speed. He pushed his pregnant wife out of the way and jumped out of the way himself, but Gonzalez was hit by the truck from behind, police said.
Gonzalez died from her injuries. No one else was hurt.
Police believe the attendant left the truck in drive instead of neutral. An autopsy has been ordered.
