A tractor-trailer collided with two vehicles Thursday afternoon in Manor Township, resulting in a diesel fuel spill and sending two people to the hospital. The crash occurred around 2 p.m. on the 1900 block of Columbia Avenue, according to East Hempfield Township Police. Authorities said the semi allegedly struck a white SUV, which was then pushed into another vehicle. Two individuals were transported to a nearby hospital with non-life-threatening injuries.
Whenever a semi-truck is involved in a chain-reaction crash, I think about whether the driver was paying full attention to the road and whether the vehicle was in good condition.
Could Distraction or Fatigue Have Been a Factor?
Collisions like this often raise questions about whether the truck driver was fully alert and attentive. Fatigue and distraction are two of the most common contributing factors in rear-end crashes involving commercial vehicles. Investigators will likely examine the driver’s schedule, rest periods, and recent driving activity to determine if fatigue could have impaired their reaction time. They may also review mobile phone records or dash cam footage to check for signs of distraction.
Were There Any Mechanical or Brake Issues With the Truck?
In this case, it’s also worth investigating whether the semi’s brakes or other critical systems were functioning properly. If the truck was overloaded, experienced brake fade, or had a malfunctioning system, those issues could explain the delayed response. Maintenance records and brake inspections will be key in assessing this possibility.
What Evidence Should Be Reviewed?
To determine what happened, investigators will likely analyze ECM (Engine Control Module) data from the semi-truck, which may show braking patterns, speed, and throttle input before the collision. Video from nearby traffic cameras or dash cams could also help establish the sequence of events. Finally, examining the road surface, skid marks, and vehicle positions can provide further insight into the movement of each vehicle before the initial collision.
Why a Complete Investigation Is Necessary
Even in crashes where the injuries are not life-threatening, a full investigation is crucial to understanding what led to the collision. When a semi-truck is involved, the margin for error is small, and the consequences can be serious. By reviewing all the facts, including driver behavior and vehicle condition, it’ll be easier to provide clear answers to those affected.
