Which type of line indicates that you may pass if there is a safe gap in traffic?

A dashed white line indicates that you may change lanes or pass if there is a safe gap in traffic. This type of line signifies that lane changing is permitted and drivers should use caution and assess their surroundings before moving into the adjacent lane. It provides flexibility for drivers to navigate safely, especially when in traffic situations that allow for such movements.

In contrast, a solid white line indicates that lane changes are discouraged, while double solid lines prohibit any lane changes altogether, signaling that it is unsafe to cross. A broken yellow line is typically used to indicate that passing is allowed, but it pertains primarily to separating traffic moving in opposite directions rather than the specifics of lane changes within the same direction. Understanding these distinctions helps drivers adhere to safe driving practices and follow traffic laws.
