While I have no "Dog in this Fight".....I am a member of the AMA, and lane splitting is an issue that receives a lot of comments and articles.
http://americanmotorcyclist.com/Rights/PositionStatements/LaneSplitting.aspx The most current information is that no state has enacted legislation that approves it. Here is some of what the AMA has said recently:
"For decades, California has been the only state to permit lane splitting. While not specifically permitted or prohibited in the California Vehicle Code, lane splitting authority comes from the California Highway Patrol. In early 2013, the CHP published lane splitting guidelines for the first time. While the guidelines do not carry the force of law, they provide clear indicators under which a motorcyclist might be cited for unsafe or imprudent behavior.
(SOURCE: Issued by the California Highway Patrol, California Motorcycle Safety Program in 2013, the guidelines were rescinded in 2014 for administrative reasons but are still viewable at “Lane Splitting General Guidelines.”
Legislatively, there has been state-level activity on lane splitting, although to date no bill has been enacted.
(SOURCE: California 2013 SB-350 would codify lane splitting but would also impose certain restrictions on motorcyclists. Other states that have recently considered lane-splitting legislation include: Arizona (2010 HB-2475); Illinois (2006 SB-2439); Massachusetts (2007 HB-3493); Nevada (2013 AB-236); New Jersey (2012 AB-2102 and 2010 AB-140 and AB-1684); Oregon (2011 SB-463 and 2007 SB-386); Texas (2011 HB-1571 and 2009 SB-506); and Washington (2007 HB-2160 and SB-5985).
So.....if you get pulled over for lane splitting - doesn't appear that there is anything that says you are specifically "allowed" to do it. It appears that if the California Highway Patrol used their "guidelines" to determine if you are "ticket worthy" when lane splitting. (But wadda' I know....I have only been in CA once....and that was 50 years ago!).
