Final answer:
When a school bus stops for passengers on a two-lane roadway with a center turning lane, you are required to stop and remain stationary until the bus moves again or turns off its flashing red lights to ensure the safety of children.
Step-by-step explanation:
If you are driving on a two-lane roadway with a center turning lane, and a school bus stops for passengers, the action required by law is very specific. You must stop moving and remain stationary until the school bus resumes motion or deactivates its flashing red lights. This law helps to ensure the safety of children boarding or exiting the bus. It is critical to halt all traffic from both directions in this scenario to provide a safe passage for the students, regardless of whether there is a center turning lane.
