A man was struck by a truck on Savannah Highway Wednesday after he stepped out of his vehicle, possibly to remove a deer that he had hit, Charleston County sheriff’s deputies said.

The injured man was hospitalized with life-threatening injuries following the incident, Sheriff’s Maj. Jim Brady said.

The incident occurred shortly before 6:30 a.m. on Savannah Highway near the Ponderosa subdivision.

According to Brady, the driver was driving south when he struck a deer. He then turned around on the highway and stepped out of his vehicle, possibly to remove the deer, when he was struck by a passing pickup truck, Brady said.

The man’s dark clothing was difficult to see in the unlit area, Brady said.

Sheriff’s deputies initially reported that the driver was killed. Authorities later announced that the driver was taken to Medical University Hospital with life-threatening injuries, Brady said.

A second wreck further blocked northbound traffic on Savannah Highway at the viaduct, Brady said.
