Which of the following is not a recommended action when you see a traffic signal change?

When you see a traffic signal change, the recommended actions focus on safety and compliance with traffic laws. Speeding up to make the light is not advisable because it can create dangerous situations for yourself and others on the road.

When a traffic signal turns yellow, it serves as a warning to slow down and prepare to stop, unless you are already too close to the intersection to do so safely. Accelerating increases the risk of running a red light, which can lead to accidents and serious consequences.

Preparing to stop, checking mirrors, and observing pedestrians are all actions that contribute to safe driving practices. Preparing to stop helps ensure you can respond appropriately to changes in the signal, checking your mirrors allows you to be aware of your surroundings, and observing pedestrians is crucial for their safety, especially when light changes might affect them.

Therefore, speeding up does not align with the principles of safe and responsible driving in response to a signal change.
