Final answer:
The meaning of two solid yellow lines on the road and their purpose in promoting safe driving practices.
Step-by-step explanation:
The subject of this question is Driver's Education. The question is asking about the meaning of two solid yellow lines on the road. These lines indicate that neither lane of traffic can cross them unless they are turning (if it is safe to do so). No passing is allowed.
These lines serve as a clear visual indication to drivers that it is unsafe to pass or change lanes in that area. This helps to prevent accidents and promote safe driving practices.
