Disclaimer: Simulations presented below used site surveys, scene pictures and vehicle operating characteristics. These depictions represent similar lighting and weather conditions at the time of the accident. The visibility conditions during the incident are approximated in the simulations and may not accurately represent the effects of the sun ball on the windshield at the time of the incident.

These simulations are of an accident that occurred on January 14, 1999, at about 7:45 am, when a tractor semi-trailer was eastbound in the right lane of Interstate 40 near the town of Moriarty, New Mexico, and was traveling at a truck driver reported speed of 75 mph when the truck ran into the rear of a van and then a car.

Scenario 3:
This is an aerial view of the truck driver as he approached at 75 mph with a van in the right lane. In this simulation, a collision warning system is animated and included to show the lights and audible warnings as the truck approaches. The system, as animated, was modified to include an audible warning as the first light is activated. About 1.6 seconds after the audible alarm the driver starts to brake and 2.8 seconds after the audible alarm the truck is steered to the left. The truck is then steered into the left lane as it passes the van. This is a relatively easy, stable maneuver. The van and car were going about 25 mph.
