When riding behind a car, traveling in the center portion of the lane:

When following a car, you should ride in a position that allows the driver to see you in their rearview mirror. Usually, that means riding in the center portion of the lane. Because most drivers check their rearview mirrors much more often than they check their side mirrors, being in this lane position increases the chance that they will see you.

• Allows you to be seen in its rearview mirror.
• Usually makes it difficult for the driver to see you.
• Should be avoided.
