On a one-way street, what color is the broken line that marks the lanes and indicates that you may drive in any lane?

The correct answer is that the broken line marking the lanes on a one-way street is white. In traffic rules, white lines are used to indicate lanes of traffic moving in the same direction. They serve to separate the lanes and guide drivers on where they can safely travel.

When you see a broken white line, it signifies that you have the flexibility to change lanes within that one-way street, as all traffic is flowing in the same direction. It allows drivers to navigate between lanes as needed, whether for turning or passing.

In contrast, yellow lines indicate lanes of traffic moving in opposite directions, which does not apply on a one-way street. Red lines are typically used for special purposes like indicating no stopping or parking, and blue lines often signify accessible parking spaces or specific designations for emergency vehicles.
