On a two-lane, two-way road, what allows you to cross over into the opposing lane temporarily to pass a vehicle if it is safe?

Answer: C — broken yellow line

The correct answer is the broken yellow line, which signifies that it is permissible to cross into the opposing lane to pass another vehicle when it is safe to do so. A broken yellow line indicates that passing is allowed, and drivers should always ensure that they have adequate visibility and space to perform the maneuver safely. This traffic marking is specifically designed to enhance roadway safety by allowing for overtaking while delineating the contrasting directions of traffic. In contrast, a solid white line indicates that lane changes are discouraged or illegal, serving as a boundary between lanes moving in the same direction. A double solid line signifies that passing is not allowed in either direction, creating a clear restriction against crossing into the opposing lane. The term "bennett line" is not an established roadway marking and does not pertain to passing or lane changes. Understanding the meaning of these markings is crucial for safe driving and compliance with traffic regulations.
