“Full fields of world-class cars, teams and drivers, incredible competition in all four classes, impressive digital, social media and other business metrics, and, most importantly, record-breaking crowds of sports car racing fans at both the Daytona and Sebring events.” Atherton believes the new procedures will shed positive light on some of the notable situations related to our competition procedures.

About the IMSA

The International Motor Sports Association, is the backbone of the TUDOR United SportsCar Championship, which for those who don’t know, is the professional road-racing series resulting from the merge of the American Le Mans Series presented by Tequila Patrón and the GRAND-AM Rolex Sports Car Series.

The Upcoming Changes

  • A new system for cross-checking cars and drivers involved in on-track incidents.

  • Upgraded video review equipment to high definition (HD).

  • Enforcement of an IMSA rule requiring the display of the car’s number on its in-car cameras.

  • Adding an additional third driver advisor to work alongside the IMSA Race Director and two driver advisors to assist with evaluating responsibility in incidents and other on-track situations. 

The IMSA is also adjusting its full-course caution procedures to maximize green-flag running time. Changes to the flag procedures will be confirmed by ISMA Rule Book bulletin and are as follows:

  • At events where there is only one prototype class in a race, the pits will be opened for that class when the field is packed up and while GT cars are still performing the Pass-Around procedure. This change will expedite the full-course caution process by a full lap.

  • The “Lap-Down Wave-By” procedure – which provides a strategic opportunity for cars a lap or more behind to gain a lap back by staying on course while leaders make pit stops – will be more limited in its application. There will be no Lap-Down Wave-By in races less than two hours and 30 minutes in length. For races between two-and-a-half hours through six hours, the Lap-Down Wave-By will be used only once in any 90-minute period after 60 minutes from the start of a race. No Lap-Down Wave-By will be used in the last 30 minutes of a race.

  • Efforts also will be made to use “Debris Yellows” where a situation is likely to involve the simple removal of debris or the flat-tow of a stopped car to a safe location. A Debris Yellow includes the Pass-Around procedure, but the pits remain closed until the race is restarted
