here's a textbook lane positioning scenario right out of last weekend. without divulging the bicyclists demise or other particulars, i'd like to discuss riding positions on well accomodated roadways as described in this CASE STUDY
See photo below- actual roadway described
Highway speed, rural, two lane road with 12 foot shoulders. high amounts of logging truck and commercial large vehicle traffic. curves, hilly, rolling terrain. sun is low in the sky. The shoulder is swept as clean as the main travel lane.
A bicyclist is riding in one direction on the road. they are travelling 8 MPH on the uphills and 20-35 MPH on the downhills.
Truck traffic is passing frequently in both directions. two trucks appear to be closing from a considerable distance on the bicyclist at the same rate. where does the cyclist ride to maximize safety? does the bicyclist need to ascertain the trucks notice them by slowing noticably in the bicyclists rear view mirror? what does a bicyclist do if there is traffic spaced 40 seconds apart on this road and the bicyclist is travelling 8 miles per hour? if the traffic is 2 minutes apart? 15 seconds?
without any upcoming traffic hazards or driveways, is there any justifiable reason to take the lane to prevent a driver from drifting into the twelve foot shoulder?
would a bicyclists' visibility help to provide cognitive awareness more so than lane position on this road, to allow the drivers of the trucks near certain recognition of a bicyclist regardless of road position?
