Janie Vernell Cunningham, 37, a driver for Greyhound Bus Lines since 1975, was killed Oct. 10 in a traffic accident on an approach to the Key Bridge in Baltimore. She lived in Clinton.

A spokesman for the Maryland Toll Facilities Administration said the accident occurred when Mrs. Cunningham, who was alone in a passenger car, tried to pass another vehicle and struck an oncoming car head-on. The driver of the second car was treated at a Baltimore hospital and released, authorities said.

Mrs. Cunningham, who was born in Warren County, N.C., attended Cardozo High School here.

About 1970, she went to work for Trailways as a hostess. She began her career at Greyhound about 1973 as an information clerk in schedules and fares. Two years later, she became a driver.

Mrs. Cunningham was a member of the Broadway Southernaires, a gospel group, and the Pumpkin Hill Baptist Church in Laurel.

Survivors include her husband, Bradford Cunningham, and a daughter, Vernice Clanton Cunningham, both of Clinton; three stepchildren, Sheila Cunningham of Washington, and Bradford Jr. and Michael Cunningham, both of Suitland; her mother, Beulah Clanton of Landover; three brothers, Alexander Clanton of Boston, Robert Clanton of Landover, and Royal Clanton of Forestville, and three sisters, Ann Grady of Baltimore, Faucenia Gardner of Arlington, and Tassie Gantt of Hyattsville.
