For those riding in California, ... none of the sites posted above have updated their databases for California officially legalizing Lane-splitting. Here is a copy of a post I made in another thread, ...
Here is some history on Lane Splitting, for those that still don't know it's legal in California, (No longer in the grey area of the law), ...
ARTICLE 2. Other Speed Laws [22400 - 22413] ( Article 2 enacted by Stats. 1959, Ch. 3. )
22400. (a) No person shall drive upon a highway at such a slow speed as to impede or block the normal and reasonable movement of traffic unless the reduced speed is necessary for safe operation, because of a grade, or in compliance with law.
No person shall bring a vehicle to a complete stop upon a highway so as to impede or block the normal and reasonable movement of traffic unless the stop is necessary for safe operation or in compliance with law.
(b) Whenever the Department of Transportation determines on the basis of an engineering and traffic survey that slow speeds on any part of a state highway consistently impede the normal and reasonable movement of traffic, the department may determine and declare a minimum speed limit below which no person shall drive a vehicle, except when necessary for safe operation or in compliance with law, when appropriate signs giving notice thereof are erected along the part of the highway for which a minimum speed limit is established.
Subdivision (b) of this section shall apply only to vehicles subject to registration. (Amended by Stats. 1979, Ch. 364.)
4. Opening a vehicle door to impede a motorcycle is illegal (CVC 22517).
CHAPTER 9. Stopping, Standing, and Parking [22500 - 22526] ( Chapter 9 enacted by Stats. 1959, Ch. 3. )
22517. No person shall open the door of a vehicle on the side available to moving traffic unless it is reasonably safe to do so and can be done without interfering with the movement of such traffic, nor shall any person leave a door open on the side of a vehicle available to moving traffic for a period of time longer than necessary to load or unload passengers.

If you ride in California and Lane Split, copy the above, print it, and keep it in your wallet. Show it to anyone that disputes it and have them look it up for themselves.
Ride your bike, your way, at your speed, for your reasons. Never let anyone else decide who, where, how and why you should ride.
Ride for the love of riding and nothing else and every trip will be an adventure and a memory to be relived over and over.
