determines the final ruling. However, for reviews that take place during coach's challenges, the on-ice officials determine the final ruling. Junior Hockey Similar to the National Hockey League, Junior Hockey leagues, such as the CJHL also use instant replay with a Video Goal Judge to initiate and be responsible for the review of all goals. The Video Goal Judge may also be asked to verify the time during a game. Referees utilize instant replay for on-ice review of Major Penalties as well as Match Penalties, in which they look to confirm or modify their original call on the ice. Video review on a play involving a goal must be done immediately after the play has concluded, and before the puck is dropped again. On-ice calls cannot be overturned once the puck is dropped again and play has resumed. 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 with a caution flag on the last lap or under a green-white-checker finish. Video replay is used to determine if a car has crossed the pit entrance before the pit was closed for a yellow flag. 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 cautions). IndyCar also utilizes instant replay for similar reasons. The most notable use of replay in recent years occurred during the 2008 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 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 seconds or 12⅛ inches, in the second closest finish in the twelve-year history of the series. 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
