Research shows "Cyclists may use full lane" communicates better than "Share the Road" signs -- Science of Us

You might be most familiar with the signs that say “Share the Road,” but a team of researchers from North Carolina State University argue that this language is part of the problem. It's too vague, for one, and it may insinuate that it’s mostly up to the cyclist to move out of the way of vehicles. (At least one state – Delaware – recently got rid of these signs for precisely that reason.) Instead, the researchers suggest, the more spelled-out “Bicycles May Use Full Lane” seems to get the message across that, yes, bicycles may in fact use the full lane when necessary (even in New York) — for instance, when the road is too narrow for the cyclist to ride to the right of traffic. The study was published online late last month in PLOS ONE.
