A man was killed Tuesday on an Alabama highway when his car struck a tractor-trailer, head-on, state troopers said.

The two-vehicle crash occurred at approximately 1:50 p.m. Tuesday, and claimed the life of a Graceville, Florida, man.

Ronald K. Booker, 65, was critically injured when the 2011 Cadillac SRX he was driving collided head-on with the 1997 Western Star tractor-trailer driven by Ricky S. Miles, 44, of Ashford.

Booker was not using a seat belt at the time of the crash and was transported to Southeast Health for medical treatment.

Shortly after arriving at the hospital, Booker succumbed to his injuries and was pronounced deceased.

The crash occurred on Alabama 109 near McCallister Road, approximately 10 miles south of Dothan, in Houston County.
