Practice question

What does a double yellow line mean?

  1. No passing in either direction
  2. Passing is allowed on both sides
  3. It separates lanes going in the same direction
  4. It indicates a highway merge

Answer: A — No passing in either direction

A double yellow line signifies that no passing is allowed in either direction. This marking is a crucial traffic rule designed to enhance safety on the roads. The presence of a double yellow line indicates that the road conditions do not permit safe passing maneuvers, often due to visibility issues, curves, or other factors that could pose a risk to drivers. Understanding this traffic sign is essential for promoting safety and preventing accidents, as it encourages drivers to remain in their lanes and respect the traffic flow. In contrast, single lines or different markings would indicate alternative rules regarding passing, which is not applicable here with the double yellow line.
