Lane Splitting Legality

Out of all 50 states in the US, California is the only one that legalizes lane splitting for motorcycles. There are, however, some conditions.
-It's only allowed between inside lanes, no shoulder passing.
-It's only allowed when traffic is stopped or close to it.
-The motorcycle can not exceed 15 mph faster than traffic is moving.

NBC San Diego did a segment on Lane Splitting, and why California legalizes it. You can see the video by clicking the title link.

Thanks to the Why Bike Motorcycle Blog for the scoop on the clip.

Edit: Apparently, the speed limit rule no longer applies. According to James at Why Bike, the law now simply states that lane splitting must be done in "a safe and prudent manner". Thanks again to Why Bike for the correction.
