The sign was first included in the 2009 Manual on Uniform Traffic Control Devices. The signs can be used without or without “sharrows”. Unfortunately, the signs have been installed in very few locations in Florida. As of 15 months later, the new signs had only been installed in 3 locations within the entire state. The failure of the FDOT and local Florida governments to install the signs is unfortunate. The signs have been shown to improve safety.
In Austin, Texas, a study was conducted after a series of “Bicycles May Use Full Lane” signs were erected. The study concluded, “The results of this study suggest that “Bicycles May Use Full Lane” signs do improve bicyclist and motorist safety along routes where commuter bicyclists are common users of the facility.” You can download a PDF of report here.
The FDOT and local governments should move rapidly to utilize these signs in all locations of roads which are “sub-standard width” - where there is not enough room in the travel lane for a car to pass a bicycle with the required 3 feet of clearance. As of now, the most commonly used bicycle safety sign says, simply, “Share the Road”. This sign should be replaced, whenever possible, with the “Bicycles May Use Full Lane” signs.
The “Share the Road” sign is ineffective, ambiguous, misleading, and poorly communicates to both motorists and cyclists exact how they should behave.
At best, the “share the road” message suggests to motorists that cyclists have a right to be on the road. It may also encourage motorists and cyclists to treat each other positively. But what exactly does “share” mean? The sign does not explain.
- HOW are they supposed to share?
- What happens with heavy traffic?
- Are cyclists supposed to ride on the far right?
- Can they share the middle of the lane, or only the edge?
- Do they take turns, like children learn to “share” in preschool?
The sign which states, “Bicycles May Use Full Lane” is much improved for bicycle safety and conveying proper interaction.
This sign tells motorists to expect cyclists to “take the lane”, even if traffic is heavy and lanes are narrow. It tells motorists and cyclists – cyclists may use any portion of the lane, when necessary. The sign gives cyclists confidence to ride out into traffic and not feel relegated to the gutter. The sign advises motorists that they must accept cyclists being in front of them in the lane, preventing the motorists from passing them within the same lane of travel. The effect of the sign’s message is to teach vehicles to slow down, to teach motorists to wait behind cyclists until they can safely pass. The sign is an excellent tool to teach motorists to change lanes to overtake slower moving cyclists in narrow lanes.
Arguably, the “share the road” sign caused some cyclists to believe the involved road was “preferred” or “favored” for cycling. These cyclists felt that the installer of the sign was indicated this was a good place for cyclists to ride. This conclusion was often incorrect. The “Bicycles May Use Full Lane” sign probably sends a more accurate message. An informed cyclist will understand the new sign to mean there is not a designated and separated bicycle lane on the upcoming roadway. The cyclist may also understand that he/she may use the full lane because the lane width is substandard, too narrow, to allow him to ride to the right and be passed with 3 feet clearance.
