    Accident Reconstruction For Off-Road All Terrain Vehicles (ATV's)
    During 1990, the Specialty Vehicle Institute of America (SVIA) with the assistance of the American National Standards Institute (ANSI) published the first standard for ATVs referred to as ANSI/SVIA-1-1990. During 2001, ANSI/SVIA revised this standard referred to as standard ANSI/SVIA 1-2001. The standard was revised again during 2007 and again in 2010 and is referred to as standard ANSI/SVIA 1-2010.

    Synopsis: The Basic Process Of A Traffic Accident Reconstruction
    A Traffic Accident Reconstruction is a process by which an engineer determines from all available information and evidence how and why a traffic accident occurred including but not limited to pre-impact and post impact vehicular velocity vectors, pre-impact and post impact vehicular direction vectors, vehicular change in velocity (Delta-V), momentum vectors, vehicles' point of impact on the roadway, vehicular visibility by a driver, vehicular crash data retrieval reports if assessable, accident factors and causes.

    The Physics Of Collision
    When we drive our vehicles down the road, we are driving them at a certain velocity and direction. All vehicles have weight and mass to the order of a few hundred pounds for a motorcycle, a few thousand pounds for a large SUV or luxury car or several tons for a tractor-trailer truck. When our vehicles move at speed down the road, they create energy by virtue of their mass and forward velocity

    Expert Witness Was Free to Change his Mind, 8th Circuit Rules
    When an expert has a change of mind about his or her own opinion, what does it mean to the case? A recent decision from the 8th U.S. Circuit Court of Appeals sheds new light on this recurring question. The issue is one that comes up with surprising regularity, sometimes with dramatic consequences.
