What should motorcyclists avoid in the center of a traffic lane?

Motorcyclists should avoid areas where oil and grease buildup is present in the center of a traffic lane because these substances can create extremely slippery conditions, especially in wet weather. Oil and grease can reduce traction significantly, increasing the risk of skidding or losing control of the motorcycle. It is crucial for motorcyclists to maintain optimal control and stability, particularly during maneuvers like turning or stopping.

While other factors like concrete and gravel, uneven road surfaces, and pedestrian crossings can also pose hazards, oil and grease specifically present a slippery hazard that can lead to accidents. Motorcyclists should be particularly vigilant about these road conditions to ensure their safety on the road.
