What is the rule regarding crossing a double solid yellow line?

The rule regarding crossing a double solid yellow line is that crossing is prohibited at all times. This is a crucial traffic regulation intended to maintain safety on the roads. The double solid yellow line indicates that passing or changing lanes is not permissible, primarily because it typically marks the separation of lanes moving in opposite directions where visibility and safety are compromised.

When drivers see a double solid yellow line, it signals that there are potential hazards on the other side of the line, which can be a number of factors such as oncoming traffic, road conditions, or lack of visibility due to curves. Adhering to this rule helps prevent accidents and ensures that traffic flows smoothly without unnecessary risks.

The other options either suggest that crossing is permissible under certain conditions or for specific situations, which contradicts the clear intent behind the double solid yellow line regulation. Understanding and following this rule is vital for safe driving practices.
