Both the California DMV and California Highway Patrol have removed any language pertaining to motorcycle lane splitting from their websites and printed materials, in what appears to be an effort to distance themselves from any perception of endorsing the practice. California is the only state that allows (or rather, doesn’t disallow) lane splitting or lane sharing by motorcycles. For the record, I still split lanes on occasion but do so rather conservatively. You can read the article I wrote about it a few years ago here:
Lane Splitting — Time Saver or Insanity?
