Commentary by Attorney Michael Grossman
Rear-end collisions at intersections can appear straightforward, but the real answers often lie in the details that aren’t visible from a quick scene review. Understanding why a driver didn’t slow for stopped traffic can be the difference between closing a case and finding a preventable cause.
1. Did the authorities thoroughly investigate the crash?
A careful investigation would involve more than noting damage to the vehicles. It means documenting braking distances, checking for skid marks, and reconstructing the approach to the intersection. Understanding the Ford’s speed in the moments leading up to impact and whether the driver attempted to stop is key.
2. Has anyone looked into the possibility that a vehicle defect caused the crash?
Brake failures, accelerator malfunctions, or even issues with driver-assist systems can lead to a situation where a driver can’t slow in time. A mechanical inspection of the Ford should be part of the process to rule out or confirm these possibilities.
3. Has all the electronic data relating to the crash been collected?
Modern vehicles often record speed, brake pedal use, and throttle position. The Ford’s event data recorder, along with any available intersection camera footage, could clarify whether this was a case of inattention, a mechanical fault, or something else entirely.
The best conclusions come when investigators explore every possible explanation, not just the most obvious one.
Takeaways:
- Intersection crashes need a full review of driver actions and vehicle capabilities.
- Mechanical failures, even in newer vehicles, can contribute to rear-end collisions.
- Electronic data can confirm whether brakes were applied before impact.
