Final answer:
You should turn on your right turn signal and move your vehicle to the right shoulder during an enforcement stop to safely acknowledge a police officer's authority.
Step-by-step explanation:
During an enforcement stop, you should turn on your right turn signal before moving your vehicle to the right shoulder of the road. This action signals to the officer that you acknowledge their presence and are complying with the request to pull over safely. It's part of being a responsible driver and respecting the authority of the police officer. Acknowledging an officer's presence by stepping out of your vehicle or moving onto the center median are not recommended actions and can be unsafe.
