What is a Sideslap?

A sideslap collision normally occurs in near 90 degree impacts where the vehicle rotate towards each other and create a slap of their sides after the initial impact.
For more detailed information see post on sidelaps here at
  • Above is a snip of a simulation of a 90 degree collision (for more info, see 2007 NYSTARS sideslap crash) with the velocity vectors displayed in the second video.
    We have also posted up a graphic and tabular summary of the results which includes the positions, velocities, momentum and kinetic energy calculations
    Notice how the velocity vectors direction and magnitude changes during the sideslap.
    Below are some pictures from the 2007 NYSTARS test:
    NOTE the movement between initial and secondary 'sideslap' impacts!
