What do yellow center lines indicate on a roadway?

• A. One-way traffic in a single lane
• B. Two-way traffic, flowing in opposite directions
• C. Special lanes for emergency vehicles
• D. Bus-only lanes during peak hours

Answer: (B)

Yellow center lines on a roadway indicate two-way traffic, flowing in opposite directions. This lane marking serves as a critical safety feature, as it helps drivers understand that they are sharing the road with vehicles traveling in the opposite direction. When drivers see yellow lines, they should exercise caution and be aware that passing or crossing these lines may be prohibited in certain areas, especially if solid yellow lines are present, signaling no passing zones. In contrast, the other options do not correctly interpret the meaning of yellow center lines on roadways. One-way traffic typically would be indicated by a single set of white lines, while special lanes for emergency vehicles or bus-only lanes would be designated by specific symbols or signage rather than yellow center lines. Understanding the correct meaning of roadway markings, such as yellow center lines, helps ensure safety and proper navigation on the road.
