The Bicycles May Use Full Lane sign, also referred to as BMUFL or R4-11, first officially specified in Chapter 9B of the 2009 Manual on Uniform Traffic Control Devices, is a traffic sign used in the United States to: # designate roads with lanes that are too narrow to be safely shared side-by-side by a bicycle and another vehicle to indicate that bicyclists may occupy the full lane to discourage unsafe within-lane passing, # encourage bicyclists to use the full lane to discourage unsafe within-lane passing, # encourage motorists to change lanes to pass bicyclists, and # warn motorists that bicyclists may be using the full lane. The sign consists of a graphic image of a bicycle, followed by the words, "MAY USE FULL LANE". ==Sign effectiveness== A study conducted by the City of Austin in 2010 showed that placement of BMUFL signs influenced cyclists to generally ride farther from the curb (an average of .31 feet), and drivers moved further left as they passed bikes after the signs were installed, such that the percentage of motorists who passed within 3 feet of the bicyclist dropped from 44% to 0%. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bicycles May Use Full Lane」の詳細全文を読む スポンサード リンク
