The driver of a small sedan was seriously injured in a Friday morning crash with a tractor-trailer on I-285 in Sandy Springs, authorities said.

The driver, who was unresponsive at the scene, was taken to Grady Memorial Hospital with non-life-threatening injuries, Sandy Springs police said.

Officers responded just before 4 a.m. to the crash, which occurred in the eastbound lanes of the Perimeter near Roswell Road. The wreck caused delays as all eastbound lanes were shut down.

A single lane reopened about two hours later during the morning commute, and traffic delays remained heavy through the 8 a.m. hour.

Police said the tractor-trailer driver was charged with a lane violation, while the driver of the sedan still has charges pending.

No further information has been released.
