​In response to the increased number of motorcycles and fatalities on the Nation's highways, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), Public Law 109-59, Section 2010, Motorcyclist Safety, directed the Department of Transportation to develop and provide the States model language for sharing the roads safely with motorcyclists.

​Share the Road

• Motorcycles are vehicles with the same rights and privileges as any vehicle on the roadway.
• Allow the motorcyclist a full lane width. Although it may seem as though there is enough room in the traffic lane for an automobile and a motorcycle, remember the motorcycle needs the room to maneuver safely. Do not share the lane.
• Approximately one-half of all motorcycle crashes involve another vehicle. Nearly 40 percent were caused by the other vehicle turning left in front of the motorcyclist.
• Motorcycles are small and may be difficult to see. Motorcycles have a much smaller profile than vehicles, which can make it more difficult to judge the speed and distance of an approaching motorcycle.
• Always signal your intentions before changing lanes or merging with traffic. This allows the motorcyclist to anticipate traffic flow and find a safe lane position.
• Remember that motorcyclists are often hidden in a vhicle's blind spot or missed in a quick look due to their smaller size. Always make a visual check for motorcycles by checking mirrors and blind spots before entering or leaving a lane of traffic and at intersections.
• Don't be fooled by a flashing turn signal on a motorcycle - motorcycle signals usually are not self cancelling and riders sometimes forget to turn them off. Wait to be sure the motorcycle is going to turn before you proceed
• Remember that road conditions which are minor annoyances to you pose major hazards to motorcyclists. Motorcyclists may change speed or adjust their position within a lane suddenly in reaction to road and traffic conditions such as potholes, gravel, wet or slippery surfaces, pavement seams, railroad crossings, and grooved pavement.
• Allow more following distance, three or four seconds, following a motorcyle so the motorcyclist has enough time to maneuver or stop in an emergency. In dry conditions motorcycles can stop more quickly than a car.
