This two-vehicle collision occurred May 22, 2007, at about 4:30 p.m., on Prospect Street, in Ewing, Mercer County, New Jersey. The collision involved a 1991 Dodge Spirit passenger car, driven by Car Driver, and a 2001 Suzuki motorcycle, operated by Motorcyclist.

Car Driver was turning left from northbound Prospect Street into Dawes Avenue when she collided with Motorcyclist, who was southbound on Prospect Street. Both Car Driver and Motorcyclist were injured in the collision.

This investigation was performed to determine if the Car Driver’s driving was improper in a manner that was a cause of the collision.

Findings

Based on the information available, subject to change with new information, and to a reasonable degree of professional certainty, I conclude:

  1. Motorcyclist’s speed at impact was 34 to 38 mph.
  2. Motorcyclist and his motorcycle were 45 to 150 feet from impact when Car Driver started to turn.
  3. There were no obstructions to Car Driver’s view of the oncoming Motorcyclist and his motorcycle.
  4. Car Driver should have seen the approaching Motorcyclist and his motorcycle. Yet Car Driver said that she didn’t see Motorcyclist and his motorcycle prior to impact.
  5. Car Driver did not see the motorcycle that was there to be seen. Car Driver was inattentive.
  6. Motorcyclist’s speed in excess of the speed limit was not a cause of Car Driver not seeing him when she started her turn.
  7. Motorcyclist was alert and reacted promptly to the unexpected condition of Car Driver turning across his path.
  8. Car Driver’s inattentive driving was the cause of this crash.

Low Speed Collision - Experts Reconstruct Crash to Determine Injury Causation

Robson Forensic was retained to determine if the forces generated in a two car, same direction crash were sufficient to cause injuries. The Plaintiff was driving slowly, approaching a stoplight, when the Defendant changed lanes and collided with the Plaintiff’s right front fender. Crash Reconstruction Expert, Steven J. Becker, reconstructed the crash to determine the speed and duration of the collision and calculated the change in velocity. One of our biomechanical experts then evaluated Plaintiff medical records and using Becker’s calculations, determined that the forces generated by the collision were insufficient to cause the Plaintiff’s injuries.
