IndyCar is continuing to investigate the cause of the 15-car crash that led to the death of Dan Wheldon at Las Vegas Motor Speedway earlier this month.
A two-stage investigation is already underway into the accident, that also caused injuries to a number of drivers; including Will Power, Pippa Mann and JR Hildebrand.
"We must continue to move forward with a thorough investigation," said IndyCar CEO Randy Bernard.
"Fortunately, that has already begun, and we have the protocols in place to get this done. This was a tragic accident, and IndyCar needs to understand everything possible about it."
The first phase of the investigation is already underway, with an internal team of safety and competition officials evaluating data from the accident data recorders and accelerometers of the 15 cars involved.
An analysis of all the cars involved, of the personal safety equipment used, of photos, videos and timing and scoring data from the accident and its aftermath and the post-incident reports from race control and track safety crews.
Stage two of the investigation will use the findings of stage one to influence future safety procedures in IndyCar racing in a bid to minimise risks.
