There a road about 2 miles long that I have to ride to get to the highway. Theres a gravel plant where many big gravel trucks use that road. When I hear them coming I just get off my bike and get to the left side of the road and walk it till they are gone. 4 trucks passed me today in one instance and they slowed down for me a long ways away but i wouldnt take the chance riding on the right side cause one truck passes me and the other truck wouldnt see me good cause of the dust. I guess I ride like normal till I hear them trucks. I can hear them miles away.
