Induction ceremonies were held on the Wednesday evening prior to the Winston 500 in October at Talladega before being moved to December for both 1993 and 1994. After the Speedvision Dome was opened in 1996, all subsequent induction ceremonies took place there, four days prior to the Winston Select 500 at Talladega in late April. Individuals were nominated and voted on by a panel of between 120 and 153 international motorsport writers as well as IMHOF inductees, who selected one or two new members or "old timers" (living inductees) from the nominations list. The nominations list was formed by candidate names sent by panel members, and 20 finalists were chosen, from which all panel members cast preference votes.
