What type of lines may be crossed only when making a left turn?

The correct answer is that double solid yellow lines may be crossed only when making a left turn. In Virginia, as in many other states, double solid yellow lines indicate that passing in either direction is prohibited. However, there is an exception: drivers are allowed to cross these lines when it is necessary to make a left turn into or from a roadway, or to enter or exit a driveway or private road. This rule is designed to ensure safety while allowing necessary maneuvers in specific situations.

In contrast, broken yellow lines indicate that passing is allowed, and solid yellow lines typically suggest that passing is not allowed, but with certain contexts or exceptions, such as for left turns at intersections or driveways. Solid white lines are used to help guide drivers and indicate lanes that should not be crossed for most driving conditions. Knowing the distinctions between these types of lines helps promote safe driving practices and adherence to traffic laws.
