What does a double solid yellow line indicate?

Answer: B — Passing is not allowed in either direction

A double solid yellow line signifies that passing is not permitted in either direction of travel. This means that vehicles are not allowed to cross the lines to overtake or pass other vehicles. The presence of double solid lines is a clear indication that the road conditions do not permit safe passing, which can be due to limited visibility, road curvature, or other hazards. This marking is put in place to enhance safety and reduce the risk of collisions, ensuring that drivers remain in their lanes without the risk of entering oncoming traffic.
