To discourage other drivers from sharing your lane, it is usually best to ride:

• A. In the center portion of your lane.
• B. In the left portion of your lane.
• C. On the shoulder of the road.
• D. Near the edge of the lane.

Answer: (A)

Being visible and leaving room on both sides is the key to preventing other drivers from sharing your lane. Riding in the center portion of the lane maximizes your visibility to drivers in adjacent lanes and gives you the widest safety margin to maneuver if something starts to drift into your space. When you’re centered, a car trying to squeeze into the same lane would have to cross a larger, more obvious gap, making it less likely to attempt to share the lane.

If you move toward the left portion, you become less visible to drivers in the left lane and you’re closer to oncoming hazards or turning vehicles. Riding near the edge or on the shoulder reduces your escape space and exposes you to debris, uneven surfaces, and doors from parked cars, increasing the risk if a driver does try to share your lane.

So, staying in the center of the lane helps you be seen and keeps the most room for reacting to hazards, making lane sharing less likely.
