Final answer:
When law enforcement activates lights/sirens, drivers should immediately yield to the right side of the road safely. This observes the officer's authority within their professional scope.
Step-by-step explanation:
When observing law enforcement lights and/or sirens activated behind you, the correct course of action for drivers is to immediately yield to the right side of the roadway.
This response respects the authority of the law enforcement officer to command traffic for safety and operational reasons. Unlike a request to perform personal tasks which would be out of their scope of authority, pulling over is a standard protocol in response to an officer's indication.
It is important to execute this maneuver safely, slowing down and signaling as necessary without abrupt or hazardous actions like braking immediately or accelerating.
