Riding in the center portion of your lane is an effective strategy to discourage other drivers from trying to share your lane. Positioning your motorcycle in the middle of the lane helps to create a visual barrier, making it less likely for drivers to encroach on your space. This placement also provides the best line of sight for you as a rider and can help in avoiding hazards like potholes or debris that are often found towards the edges of the lane.
Choosing the center of your lane signals to other road users that you occupy that space, reinforcing the idea that it is not safe or permissible for them to drift into that area while passing. In addition, by riding in the center, you can maintain a safe distance from parked cars, reducing the risk of being struck by a car door opening or any side-swipe incidents.
While other options like riding on the edge or the right side of the lane might not clearly communicate your space needs to surrounding drivers, positioning yourself centrally is the most effective choice for enhancing your visibility and safety on the road.
