, this is incomplete:
This are the speed penalties in TAR history
1. Andy & Laura: 92-min penalty starting next leg (30 minutes + 2 min x number of km over speed limit which in their case was 42km) b
2. Nick & Starr: 30 min penalty Leg 4, never shown
3. Terence & Sarah: 30 min penalty next leg, pushed them from 3rd to 5th
TAR 2 had two such penalties on the same task in its leg in Namibia, and IIRC, there was another one in the early seasons, but I'd have to research it to tell you which one that was. It was not the Millie-Chuck one, as it wasn't their speeding, but their inability to drive safely that came into play.
