The oily strip down the center of a lane:

While the center strip of the road can be oily, it usually provides enough traction for safe riding, unless it is raining. The oily strip is usually no more than two feet wide, so motorcyclists can generally ride on either side of the strip and still be in the center portion of the lane.

• Should only be traveled upon if you are sharing the lane with another vehicle.
• Usually provides adequate traction for riding, unless it is raining.
• Should be avoided at all times.
