What is the first step when approached by a police officer while driving?

When approached by a police officer while driving, the first step is to pull over to a safe location and stop. This action demonstrates that you are complying with the officer's request and allows for a safe interaction on the roadway. It is essential to choose a safe spot that does not obstruct traffic, such as the shoulder of the road or a nearby parking area, to ensure the safety of both yourself and the officer.

Continuing to drive until signaled could lead to misunderstandings and potential safety issues, as it may be interpreted as noncompliance. Waving to the officer is not a proper response; it does not convey an understanding of the situation or promote safety. Turning off your engine immediately can be premature; it is more important to first stop the vehicle in a safe manner before addressing further actions. Thus, safely stopping the vehicle is the most appropriate and responsible response when signaled by law enforcement.
