When is it acceptable to cross double yellow lines?

Crossing double yellow lines is typically prohibited because they indicate that passing is not allowed in either direction. However, it is acceptable to cross double yellow lines to make a left turn into or out of a driveway or onto another street. This allows for safe maneuvering at intersections or when entering a property, as you are temporarily leaving your lane to access a specific location.

The other choices reflect scenarios that do not adhere to traffic regulations regarding double yellow lines. Crossing at other times, such as whenever you want or when no other cars are nearby, does not consider the safety implications for oncoming traffic and could lead to dangerous situations. Additionally, crossing double yellow lines solely to pass slower vehicles is not allowed, as it contravenes the purpose of the double yellow line, which is to prevent passing in areas where visibility is limited and safety is a concern.
