I just heard on the news that the California Highway Patrol, after receiving thousands of complaints from motorists, has issued new regulations (guidelines?) for when motorcycle riders will receive tickets for splitting lanes (filtering) on State highways. The CHP now will give tickets (for what, I am not sure, but they have lots of options) to riders splitting lanes where traffic is moving in excess of 30 mph.
I knew this was going to happen. After seeing riders split lanes on the freeway while traffic was moving at 70 mph, I figured that the hammer would come down soon. At least the State legislature hasn't passed any laws prohibiting the practice - yet.
