The center portion of a lane often contains an oily strip. This strip:

Oily drippings from cars collect in a strip in the center of a traffic lane. Unless the road is wet, this area will generally still provide enough traction for motorcyclists to ride safely. Because the strip is usually no more than two feet wide, it is often possible to ride to one side of the strip and still be in the center portion of the lane.

• Is not safe for motorcyclists at any time.
• Is usually safe for motorcyclists, unless it is raining.
• Should always be avoided since other parts of the lane do not have the oily strip.
• Adds to traction for most motorcycle tires.
