People who saw a 'Bicycle May Use Full Lane' sign were likelier to respond in ways that recognized bicyclists' right to use the road than people who saw no sign.

Co-author George Hess from North Carolina State University said, "'Share the Road' signs are common but what that means in terms of how drivers and bicycle riders should interact can be ambiguous. Misunderstandings on the road can be deadly."
Peterson further added, "Personal safety probably ranks as the most important factor deterring people from commuting by bicycle, so anything we can do to improve safety, and perceptions of safety, is incredibly important."
For the study, researchers administered a web-based survey, using Twitter to recruit 1,800 survey takers. They found that survey takers who saw a 'Bicycle May Use Full Lane' sign were more likely to respond in ways that recognized bicyclists' right to use the road than people who saw no sign. On the other hand, those who saw a traditional 'Share the Road' sign with a bicycle image showed no significant difference in response from those who saw no sign at all.
The study was published in PLOS One.
