NightTime Head on Collision
Was retained by defense council, Utah State Attorney Generals Office, to determine any Human Factors Issues relative to a head on collision at an intesection near Salt Lake City. A night time video was recommended and subsequently produced that dramatically demonstrated a key human factors perceptual consideration. A woman driver caused the accident at the intersection by turning left in front of an oncoming truck. She claimed she could not see the truck headlights because of all the other lights in the background. The video clearly proves that she should have been able to see the truck headlights since they were moving relative to all the background lights that were stationary.

Student Driver Left Turn Accident
Was retained by defense council, an attorney for an insurance co. to examine an accident that occured when a student driver attempted to make a left turn and it did not look for oncoming traffic. Being a student driver with a learners permit he was supposed to have a licenced driver with him in the front seat. Instead the licensed driver, his 5 feet six inch tall sister, was in the back seat with her girl friend. The objective of this computer graphic video was to demonstrate that the front passenger seat headrest and the door post blocked her view of the oncoming vehicle. She should have been in the front seat.

Vending Machine Tipover
A 14 year old boy put money in this canned drink machine but no drink came out. He then rocked the machine to get his drink. Unfortunately due to a very high center of gravity, only 10 degrees of tilt would tip it over. The boy died several days later of injuries cause by the machine pushing him against the oposite wall. This machine should have had a warning as well as brackets that would have secured the machine to the wall. These brackets were made available to the vending company 1 1/2 years before the accident but they chose not to use them.
