The driver of a tractor-trailer carrying propane was killed in a wreck in northern Orange County just after 6:30 this morning.

All northbound lanes of NC 86 near Cedar Grove were closed after the wreck at the intersection of NC 86 and Sawmill Road.

State Troopers say a preliminary investigation shows a 2007 Chevrolet sedan was traveling west on Sawmill Road toward NC 86 in Cedar Grove when it failed to stop at a stop sign and traveled into the intersection, striking the right side of the tractor trailer.

The tractor trailer then overturned and caught on fire, according to law enforcement. The sedan came to rest in a near-by yard.

The driver of the truck was pronounced dead at the scene by EMS personnel.

The driver of the sedan was taken to Duke Hospital with serious injuries, according to authorities.
