Accident Report Detail

 
Deaton Company, Inc., Truck/Automobile Collision, Chattahoochee River Bridge, I-20

Executive Summary

‚ÄčOn August 21, 1973, a passenger car and a truck, both westbound, collided on the Chattahoochee River Bridge on I-20 in Cobb County, Georgia. Traffic was congested and moving slowly in the right westbound lane from the Six Flags Road off-ramp eastward to the vicinity of the Chattahoochee River Bridge. The driver of the car, apparently attempting to avoid the traffic ahead, veered from the right lane into the left westbound lane, where the car was struck by the overtaking truck. Four of the five occupants of the car were killed, and the other severely injured.


Probable Cause

‚ÄčThe National Transportation Safety Board determines that the probable cause of this accident was the failure of the driver of the car to control her automobile while attempting to avoid unexpected slower moving vehicles ahead. Her failure resulted in an erratic move to the left and into the path of the overtaking truck.

Contributing to the accident were unexpected congestion which required a hazardous stop in the right lane, and land-use practices that permitted the generation of traffic in excess of the safe and efficient operating capacity of the roadway.
