Practice question

What does a solid yellow center line indicate on your side of the road?

  1. Merge ahead
  2. Yield to pedestrians
  3. Pass with caution
  4. Not pass

Answer: D — Not pass

A solid yellow center line on your side of the road indicates that passing is not allowed. This marking is used to signify that visibility is limited or that there are potential hazards ahead, suggesting it is unsafe to overtake another vehicle. Motorists should adhere to this line to ensure safety for all road users, as it functions as a regulatory measure to prevent accidents in areas where passing could be particularly dangerous. While other markings or signals might provide different directions, the solid yellow line clearly communicates the need to stay in your lane without attempting to pass any vehicles.
