Lane-Splitting

Lane-sharing/splitting in California is NOT
against the law!  Lane-sharing/splitting is
very common in Europe... it is called Filtering.

Due to "politics", the California Highway Patrol's own lane splitting article was removed from the government site (REALLY!).  However, "allowed" lane splitting is still in effect, and I have the information below, that was copied from the original California Highway Patrol's website.   Again:  this is still in effect.

In early 2013 the CHP published its safety tips on its website, & motorcyclists hailed it as a breakthrough in traffic safety.  California was the only state in the country with sort-of legal lane-splitting, but state authorities had never, until then, told motorcyclists HOW to weave the white line safely.

"Really, it has been limited anarchy out there," said Sgt. Mark Pope, statewide motorcycle safety coordinator for the CHP, at the time. "Nobody has provided any guidance, so we decided it was time to figure that out."


FYI...here are some of the guidelines for motorcycle lane-splitting that were removed from the California Highway Patrol's website:

-- Travel no more than 10 mph faster than other traffic - danger increases at higher speed differentials.

-- It is not advisable to lane-split when traffic flow is at 30 mph or faster - danger increases as overall speed increases.

-- Typically, it is safer to split between the No. 1 and No. 2 lanes (the lanes farthest to the left) than between other lanes.

-- Consider the total environment in which you are splitting, including the width of the lanes, size of surrounding vehicles, as well as roadway, weather & lighting conditions.

-- Be alert and anticipate possible movements by other road users.

-- Don't put yourself in dangerous positions.

-- If you can't fit, don't split.

Lane-splitting, a particular time-saver on such as Bay Area bridges & hundreds of other traffic choke-points, has been around almost as long as motorcycles. 
For decades it was necessary because bikes could overheat if they stopped moving. Newer motorcycles have more advanced cooling systems, but lane-splitting is still considered a safety tactic to prevent being rear-ended. It is also true that overheating still happens regularly... as traffic in some areas of California cities are abominable during Rush Hours.

Filtering, as it is called in Europe, is very common.  Lane-splitting is legal in most areas of Europe and Asia. CAR DRIVERS EXPECT IT.


Actual safety data PROVES that properly done lane-splitting is SAFER than NOT doing so!....yes, REALLY!!!!
One of the more detailed studies was done by the Safe Transportation Research & Education Center, at University of California at Berkeley.  It confirmed prior work done by various Agencies and groups.  Here is something to read:
http://www.latimes.com/business/autos/la-fi-hy-lanesplitting-safe-uc-berkeley-study-20150529-story.html

There have been other studies regarding the safety of lane-splitting.

Lane splitting is not illegal in California.  You, as a lane-splitting motorcyclist CAN BE CITED FOR UNSAFE practices, such as unsafe speed or unsafe lane changes...but the California Highway Patrol is quite lenient, providing you are not egregiously being unsafe.  The California Highway Patrol allows it, without writing citations/tickets, if done safely. Many do it rather UNsafely, & do not obey the recommendations in that link.  It is then up to the CHP, whether to ignore the rider...or not.

As published in BMWMOA in the July 2015 issue:
"Keep in mind that it's impossible to have an informed opinion on lane splitting if you haven't spent three to six months doing it in California".

I would add, or, Europe, Asia, etc.    ...and...."Don't hate what you don't understand".

.....Is Snowbum "promoting" lane-splitting:  NO; just laying out the facts. Has Snowbum done it:  Yes, when he lived in Los Angeles, and when in some areas such as San Francisco area freeways, etc... when traffic is very stop and go (little go, more stop).
