In which lane position is there likely to be less buildup of oil and grease from other vehicles?

The center lane position is typically the best choice when considering roadway debris and fluid buildup, such as oil and grease from vehicles. This position is usually farther away from the edges of the roadway, where oil and other contaminants tend to accumulate, particularly from vehicles leaking fluids. The left and right lane positions are closer to the curbs and shoulder areas, which have a higher likelihood of collecting oils and other residues from stopping or parked vehicles.

Additionally, the blind spot option is not viable because it does not pertain to a specific lane position that offers any safety or maintenance advantage concerning fluid buildup. Maintaining a position in the center allows for better visibility, maneuverability, and a reduced risk of encountering slippery surfaces. Therefore, the center lane position provides a safer riding environment by minimizing exposure to hazardous buildup from other vehicles.
