The accident happened just before 7:00 a.m. on the 6700 block of Leopard Street.
Corpus Christi police say two vans carrying workers heading to a job site were driving in the wrong direction on Leopard Street when one of the vans collided with a work truck.
The two passengers in the truck and 5 people in the van involved in the crash were taken to the hospital with non-life threatening injuries.
Police believe fog was the main factor in the crash. They are asking drivers to use caution on the road this morning due to low visibility.
Officers have not yet stated whether the two van drivers will be given a citation.
