What lane markings indicate that passing is permitted?

Broken lines are the lane markings that indicate passing is permitted. When you see a broken line, it means that you may change lanes or pass another vehicle as long as it is safe to do so. These lines show that passing is allowed, giving drivers the flexibility to overtake slower vehicles or navigate around obstacles.

In contrast, solid lines indicate that crossing is not allowed. If you see a single solid line, it means that passing is prohibited in that lane. Double solid lines further reinforce the rule against passing, as they indicate that both sides are not permitted to cross. Diagonal lines are typically used to mark areas where vehicle movement is restricted, such as no-passing zones or areas that are intended to be kept clear for safety reasons. Therefore, broken lines are the only type of lane marking that allows for passing under appropriate conditions, which is why this option is correct.
