Only when the other user is safely out of the way may the motorcycle proceed.

It is unlawful to cause the following impacts: severe erosion, damage to vegetation bordering the trail, damage to vegetation in meadows or mossy outcrops, damage to trails such that trail use by other users is hindered.
- The ACFL recommends that all motorcycle users obtain and read the Washington Off-Road Vehicle Guide from the Washington Department of Natural Resources. This guide provides information important to all motorcycle trail riders.
