What should you do when turning?

Increase your speed
Activate your turn signal
Decrease your speed
Roll down the window

The correct answer is: Activate your turn signal

When turning, it is important to activate your turn signal to indicate to other drivers your intention to turn. This allows them to adjust their driving to accommodate your turn, reducing the risk of an accident. Option A, increase your speed, is incorrect because you should always maintain a safe and appropriate speed when turning. Option C, decrease your speed, may not always be necessary as some turns can be taken at normal speed depending on the road conditions. Option D, rolling down the window, does not have any relation to the turning process and is also a potential distraction while driving.
