Heavy trucks, whether tractor-trailers, construction vehicles or garbage haulers, are involved in many serious traffic accidents due to their large weight, high centers of gravity, decreased visibility, poor handling and reduced braking efficiency. In addition, articulated tractor-trailers are subject to additional problems such as jack-knife and trailer sway instabilities. Truck tires and brakes also behave differently from those of passenger cars and require special consideration. Other truck issues that are frequently encountered include driver fatigue and clearance problems when driving through underpasses.

Expertise

Questions Answered

We have extensive experience in most aspects of truck accident investigation and reconstruction including:
  • Jack-knife and trailer sway instability simulation
  • Truck braking and skid analysis
  • Truck rollover
  • Construction vehicle accidents

Case Examples

Decapitation from Improper Cargo Stowage:
A car passenger was killed when the cargo of an oncoming tractor-trailer struck an underpass and separated from the trailer. We successfully demonstrated that the accident was not caused by an improper stowage design, but rather that the shipper failed to properly stow the cargo by not fully folding the structure before departing. This failure caused the cargo to strike the underpass, dislodging the snow plow-sized component that struck the passenger car, decapitating a passenger.

Forensic Clues: Tree Stand Accidents

By: John Ryan, BSME, PE

Tree stand accidents occur frequently during hunting season, causing a variety of injuries from broken bones to paralysis and death. Tree stand accidents involve a variety of causes, including falls from the tree stand, collapse of the tree stand, fires, self inflicted gunshot wounds, and asphyxiation. A study by the Center for Disease Control examined hunting accidents from 1979-1989. 214 of 594 deer hunting related accidents involved tree stands. 52% of these tree stand accidents were due to falls from the stand, 32% were due to collapse of the tree stands.

Forensic Engineering Experts: Golf Carts

By: Dr. Irving Ojalvo

There are roughly 9,000 golf cart related accidents requiring emergency room treatment in the United States each year. The majority of these accidents are related to either braking, cart rollover or passenger ejection. These problems are common to golf carts due to their open design, lack of seatbelts, poor braking capabilities and the uneven terrains they are driven on.
