What type of line indicates that you can pass if the line is broken?

A broken white line indicates that you can pass, as it signifies that lane changes are permitted. This marking is typically found on roads with multiple lanes moving in the same direction, allowing drivers to safely switch lanes when it is safe to do so. Conversely, a solid yellow line indicates that passing is not allowed in that lane, while double solid yellow lines reinforce this prohibition even more universally for both directions of traffic. A solid white line serves as a barrier indicating that lane changes are discouraged or prohibited. Thus, the broken white line provides the necessary indication for drivers that passing is permissible, reinforcing safe driving practices when done judiciously.
