NHP is investigating the subsequent crashes. Nine victims were transported by ground to a hospital in Reno with non-life threatening injuries. The exact hospital is unknown. One lane has been opened but traffic is still extremely backed up.

A woman waiting in traffic possibly went into labor and was transported by Care Flight into a Reno hospital.
