Final answer:
White line markings are typically found on one-way streets, delineating lanes of traffic moving in the same direction.
Step-by-step explanation:
The color of the line markings found on a one-way street is typically white. Yellow lines generally indicate that traffic is traveling in opposite directions on a two-way road. In contrast, white lines are used to delineate lanes of traffic moving in the same direction, such as on a one-way street. These lines can be solid or dashed, with solid white lines indicating that lane changes are discouraged or illegal, and dashed white lines indicating that lane changes are allowed.
