The accident happened when the couple, each in their own cars, came around a curve and ran head-on into each other.
Police in North Texas say Nicolas and Kristina Cruz were alone in their vehicles.
KETK reports highway patrol troopers confirmed, "this is a very narrow, blacktop county road and there are no markings."
Neither driver was wearing a seatbelt, and police are investigating to see if either was speeding at the time of the wreck.
The pair collided near a farm where they both worked.
Officials say it looks like neither driver hit the brakes, as no skid marks were found.
