A Grayson teen is the latest victim in a string of fatal accidents involving young people in metro Atlanta in the last three weeks.

Eighteen-year-old Geoffrey M. Whitehead died Sunday after his car struck another vehicle that had the right of way at the intersection of New Hope Road and Chandler Road in the Lawrenceville area, according to Gwinnett County police.

The accident occurred at 8:17 a.m. Whitehead was driving a 1998 Toyota Camry north on Chandler Road and stopped at the stop sign at the intersection of Chandler Road and New Hope Road.

A 2004 GMC Yukon driven by Kervon Henry, 31, of Lawrenceville was traveling east on New Hope Road. As Henry continued through the intersection Whitehead also entered the intersection and attempted to turn left onto New Hope Road, resulting in a collision.

Whitehead and his passengers, Jonathan Huge, 17, of Grayson and Huge's 16-year-old brother, were seriously injured. All three were transported to Gwinnett Medical Center. Henry was not injured, police said.

Whitehead died as a result of his injuries at about 9:48 a.m. The two other occupants were still in critical condition as of Sunday evening, said Officer Darren Moloney, Gwinnett police spokesman. He said he believed seat belts were used by the teens.

Whitehead is the seventh teen to die in an auto accident on metro Atlanta roads since May 24.

Six other teenagers died in three separate accidents recently: A 16-year-old driving a pickup full of teens was killed when he swerved off a wet Clayton County road and hit a tree, shortly before midnight Friday. An 18-year-old from Cobb County was killed in a June 8 wreck; a 15-year-old from Gwinnett County was killed May 30; a 17-year-old from Forsyth County was killed May 28; and two 16-year-olds from north Fulton County died May 24.

More than a dozen teens riding along were seriously injured in those incidents.

Bob Dallas, director, Governor's Office of Highway Safety, said parents should try to drive with their teens as long as possible because data shows this reduces the likelihood of crashes later on. Parents should also be good drivers themselves — slow down, he says — because teens learn from parents.

"They want to take chances. They want to feel the thrill, to impress their friends and they're making mistakes," he said.
