Editing Instant replay (section)

===Motorsports===
In international motorsport championships, race stewards often use instant replay to decide whether to penalize competitors for avoidable contact or pitlane infractions.

[[NASCAR]] utilizes instant replay to supplement their electronic scoring system. Video replays are used to review rules infractions and scoring disputes.
*Video replay supplements electronic scoring at the finish line (particularly the race winner) in "[[photo finish]]" situations.
*Video replay supplements electronic scoring to determine the final positions when a race ends under the safety car on either the last lap (both in regulation and in a [[green-white-checker finish]]) or when it is evident the race will reach the expiration of time without a subsequent restart.
**Starting in 2022, if the safety car situation subsequently results in the race being concluded for weather, curfew, other situation, video replay can be used to determine the final positions.  Previously, if a race is prematurely ended, the race was determined by the last completed scoring loop.  This happened as a result of the October 2021 [[Talladega Superspeedway]] [[Sparks 300]] Xfinity Series race that was curtailed because of darkness, where NASCAR determined results based on the last completed scoring loop.
*Video replay is used to determine if a car has crossed the [[Pit stop|pit]] entrance before the pit was closed when a safety car situation begins. It also determines if drivers are following pit road speed limits.
*Video replay supplements electronic scoring to determine the positions in which cars exit the pits (during the safety car).

[[IndyCar]] also utilizes instant replay for similar reasons.
*The most notable use of replay in recent years occurred during the [[2008 IndyCar Series season|2008]] [[Peak Antifreeze & Motor Oil Indy 300|Peak 300]] at [[Chicagoland Speedway]]. On the final lap, [[Scott Dixon]] and [[Hélio Castroneves]] crossed the finish line side by side, with computer scoring showing Dixon the winner by a margin of 0.0010&nbsp;seconds. However, video replay evidence clearly showed that the nose of Castroneves' car touched the line first. Castroneves was declared the winner officially by 0.0033&nbsp;seconds or {{convert|12+1/8|in}}, in the second closest finish in the twelve-year history of the series.<ref>{{cite web |url=http://www.autosport.com/news/report.php/id/70414 |title=Champion Dixon shrugs off race loss |access-date=2008-09-08 |date=2008-09-08 |publisher=autosport.com | archive-url= https://web.archive.org/web/20080911210604/http://www.autosport.com/news/report.php/id/70414| archive-date= September 11, 2008 | url-status= live}}</ref> It was later determined that the deliberate improper installation of Dixon's scoring transponder was the source of the scoring error.
*Video replay was also used extensively in the aftermath of the controversial [[2002 Indianapolis 500]]. However, fully conclusive evidence was lacking.

Broadcast stations utilize replays to show viewers a crash in greater detail.<ref>[http://sportsvideo.org/main/blog/2012/02/24/fox-refuels-nascar-coverage/ NASCAR replays with EVS servers]</ref>
