Final answer:
On a two-lane roadway with one lane in each direction, cyclists should ride in the right portion of the lane to ensure safety and visibility.
Step-by-step explanation:
When riding on a two-lane roadway with one lane in each direction, the correct position for cyclists is to ride in the right portion of the lane. This ensures that you are riding with the flow of traffic and allows vehicles to pass safely on the left if there is enough room to do so. It is also important for riders to stay as far to the right as is safely possible to avoid any potential hazards and to remain visible to other road users.
