How vehicles, people and physics intersect

Trucks, buses, car accidents, ejection, who was driving?

Impact Injury Analysis specializes in analyzing how people are injured, and unfortunately, too many injuries still occur on our roadways. Some people are injured, others just claim to be injured. Dr. Strauss has over twenty years of experience and research in investigating injuries and deaths involving tractor-trailers, straight trucks, city and school buses, motorcycles, cars, bicycles, including drivers/passengers and pedestrians. He has a commercial driver's license and knows how to evaluate the condition of air brakes. He combines his knowledge of physics, injuries and human factors to solve vehicle related accidents.

Performing injury analysis is what Dr. Strauss has been trained in and when necessary, he examines vehicles and their seatbelts; analyzes the data record from the car event data recorder or truck engine control module; identifies pedestrian head impact on a vehicle; evaluates site lines between the driver and the struck pedestrian; measures skid marks and examines roadway evidence; interviews the investigating officers and coroners. He investigates, evaluates, calculates and presents highly technical analyses in a way that can be understood by both his client and the trier of fact.

Examples of cases

  • Two young people are fatally ejected from their car that rolled over. Who was driving?
  • A chain reaction accident results in a passenger car rear-ending a city bus. How likely is it that the bus driver could be injured?
  • A child runs out into the street and is struck by a vehicle. Could the driver have avoided the collision?
  • A tractor-trailer crosses a highway median striking several on-coming cars. Minutes later, they all are engulfed in flames, including the college student driving home to his family. Could he have survived the initial impact and been conscious enough to be aware that he was trapped in a car that was on fire?
  • A child with a broken leg claims to have been sucked under a passing truck. Is this possible?
  • A pickup truck crosses the double yellow line and two on-coming traffic lanes, goes onto the sidewalk and returns to the road where it impacts a car head-on, killing the driver. Did the car driver have enough time and opportunity to see the pickup truck and take evasive action in order to avoid it?
  • A tractor-trailer on a wet highway jack-knifes going around a turn, causing it to go into the on-coming traffic lanes causing collisions and injuries. The truck driver claims the incident was an act of God and he could not have avoided it. Was this true?
