Proving Negligence in an Automatic Emergency Braking Failure Truck Accident
Modern commercial trucks are equipped with collision mitigation systems designed to prevent catastrophic rear-end crashes. These systems use front-mounted radar and cameras to detect slower or stopped traffic, automatically applying the brakes if the driver fails to react. However, like any advanced safety technology, these systems are only effective if properly maintained.
If you were rear-ended by a semi-truck that failed to slow down, an automatic emergency braking failure truck accident lawsuit can reveal if the driver or the carrier bypassed critical safety systems designed to prevent the impact.
Collision mitigation systems (such as Bendix Wingman or Detroit Assurance) utilize radar sensors on the bumper and cameras mounted behind the windshield. When functioning correctly, they can reduce impact speeds by over 90% or avoid the collision entirely, making a full-speed rear-end crash a strong indicator of system failure or neglect.
Why Collision Mitigation Systems Fail
A failure of an Automatic Emergency Braking (AEB) system is rarely an unpredictable mechanical glitch. Most failures stem from specific driver or carrier neglect:
- Manually Disabling the System: Some truck drivers find the audible warnings or automatic braking interventions annoying and will physically disconnect or bypass the radar module, leaving the truck with zero emergency braking assistance.
- Neglected Sensor Obstructions: Radar sensors must remain clear. If a driver operates in snowy or muddy conditions without cleaning the bumper sensor, the system will shut down due to obstruction, which is a failure of pre-trip safety checklists.
- Ignored Dashboard Alerts: Telematics logs record system errors. If a sensor was misaligned or broken, the system would log active faults on the dashboard, proving the trucking company operated the vehicle with known safety system failures.
Proving AEB Failure Through Telematics
To hold the carrier liable, your legal team must secure the truck's Electronic Control Module (ECM) data immediately. We will download the collision mitigation system's active fault codes and trigger logs, showing the exact moments the system detected an object, whether it applied brake pressure, or if the driver had disabled the safety systems prior to the crash.
