So what happens if a fan dies at one of these? Does the family get to sue? Or is there some kind of thing in the fine print of your ticket that Nascar is at no fault for any accidents that happen?
Has a fan ever died before?
Saturday's horrific Nationwide Series crash at Daytona wasn't the first in which fans were injured. Here's a look at some other events in which spectators were hurt due to an on-track incident:
• April 2009, Talladega: Seven fans were injured when Carl Edwards' car slammed into the catchfence at the end of a Sprint Cup race.
• May 1999, Charlotte: Three fans were k!lled and eight others were injured when a three-car crash took place in Turn 4 in a IndyCar Series race. It would be the final race at Charlotte for the series.
• July 1998, Michigan: Three people were k!lled and six others were injured when Adrian Fernandez wrecked in Turn 4 during CART's U.S. 500.
• May 1987, Indianapolis: A fan, Lyle Kurtenbach, was k!lled while attending the Indy 500 when he was struck with a loose tire from the car of Tony Bettenhausen (Roberto Guerrero actually hit the tire, which sent it into the grandstands).
