When can you resume racing after entering a yellow flag zone?

Resuming racing after entering a yellow flag zone is critical for ensuring safety during a race. The correct procedure is to wait until you have passed a green flag or lights. This signals that the danger has been cleared and it is safe to accelerate and resume normal racing speeds. The green flag indicates the end of the incident zone, and only after passing this signal can drivers safely continue racing.

While other options may involve different aspects of race procedure, they do not provide the comprehensive confirmation of safety that a green flag or lights signify. For instance, seeing a safety car ahead indicates that the track is still under caution, and drivers should not resume racing until the proper signals are received. Instructive guidance from a corner marshal is important but may not always indicate that it is safe to race again; it's essential to rely on the standardized flag signals that have clear meanings in racing. Finally, the notion that this can only happen during practice sessions is not accurate, as the same rule applies during races and qualifying sessions. Thus, passing a green flag or lights is the universal cue for drivers to safely resume racing activities.
