I'll solve this problem step by step:

Step 2:
: Understand the Question

The problem is asking about how traffic lanes are typically separated when vehicles are moving in opposite directions on a roadway.

Step 3:
: Analyze the Options

Let's consider each option: - Option A (Magnetic field) is clearly not used to separate traffic - Options B, C, and D refer to painted lines

Step 4:
: Recall Road Marking Standards

In standard road marking practices: - White lines typically separate lanes moving in the same direction - Yellow lines are used to separate traffic moving in opposite directions

Step 5:
: Make the Logical Conclusion

Yellow lines are the standard method used to separate traffic moving in opposite directions on roadways.

Final Answer

Explanation: On most roadways, yellow lines are used to indicate the center line separating traffic moving in opposite directions. This is a universal standard in traffic engineering to help prevent head-on collisions and clearly define lane boundaries for vehicles traveling in opposite directions.
