Four people were killed and two more were injured in a crash in Fayette County near the town of Clermont, Friday morning.
Freezing fog made for dangerous driving conditions Friday morning and may have contributed to the deadly crash.
Authorities say a truck lost control and hit an oncoming car head-on.
All four people in the car were killed.
Drivers are being warned to use extreme caution traveling overnight and to go only as fast as the conditions allow.
