Final answer:
The vehicle in the middle lane has the right-of-way when two vehicles from the outside lanes are trying to enter the middle lane at the same time on a 3-lane roadway.
Step-by-step explanation:
When two vehicles from the outside lanes are trying to enter the middle lane at the same time on a 3-lane roadway, the vehicle in the middle lane has the right-of-way. The middle lane is considered the merging lane, and vehicles in the outside lanes must yield to vehicles in the middle lane.
For example, if Vehicle A in the left lane and Vehicle B in the right lane both want to enter the middle lane simultaneously, Vehicle A should yield and allow Vehicle B to merge into the middle lane first.
It is important to always follow the rules of the road and yield to other vehicles when necessary to ensure safe and efficient traffic flow.
