A tractor-trailer allegedly veered out of its lane leading to a chain-reaction crash involving eight vehicles early Monday morning in DeKalb County. The crash, which occurred on the ramp from I-675 north to I-285 east, left four people injured, including the tractor-trailer driver. Officials confirmed that the truck driver was cited for failure to maintain their lane, but there are still key questions about why the truck left its lane in the first place.
Whenever I see a crash like this, I think about how crucial it is to understand what led up to it. When a large commercial vehicle drifts out of its lane and strikes multiple cars, the consequences can be catastrophic. Investigators will need to determine whether this was due to driver distraction, fatigue, or a mechanical failure.
Was the Truck Driver Fatigued or Distracted?
One of the most pressing questions in this case is whether the truck driver was paying full attention to the road. Distraction—whether from a phone, navigation system, or other in-cab device—is a frequent cause of lane departures. Fatigue is another possibility, especially given the early morning hour of the crash. Investigators should review the driver’s hours-of-service logs to determine whether they had been on the road too long or failed to take required breaks.
Could a Mechanical Issue Have Played a Role?
Mechanical issues, such as a steering failure or brake malfunction, can also cause a truck to leave its lane unexpectedly. Investigators should examine the tractor-trailer’s Engine Control Module (ECM) for any indications of sudden braking or irregular steering inputs. A review of the truck’s maintenance records may also reveal whether there were any known defects or overdue repairs that could have contributed to the crash.
Key Evidence That Should Be Examined
A thorough investigation will require reviewing dashcam or traffic camera footage, ECM data, and witness statements from the other drivers involved. Investigators should also inspect the truck for any mechanical failures and analyze the driver’s hours-of-service records for signs of fatigue.
The Need for a Full Investigation
Crashes involving multiple vehicles and large commercial trucks can be particularly complex. In my experience, a lane departure like this often has an underlying cause that needs to be uncovered—whether it’s driver fatigue, distraction, or a mechanical failure. A complete investigation will be necessary to ensure accountability and to provide answers to those injured in the crash.
