What is the proper way to resume normal speed when encountering a green flag?

Resuming normal speed when encountering a green flag indicates that the track is clear, and it's safe to proceed. The proper choice to make in this situation is to resume normal speed, as this suggests that the driver can return to the previously established safe operating speed after confirming that it is safe to do so.

While there may be scenarios where gradual actions are required, the green flag specifically signifies that all conditions are favorable and that the vehicle can operate at its regular speed. The green flag essentially signals a return to the standard pace, making it the most straightforward and appropriate response in this context.
