Includes a comparison of motorcycle rear end accidents in California versus comparable states, finding that “Motorcycle rear-end impact deaths as a percentage of all motorcycle deaths is quite a bit higher than the all-vehicle rear-end impact percentage in Florida (12.7% vs. 8.5%), Texas (10.8% vs. 7.5%), and the US (9.0% vs. 6.2%). In California, the percentages(8.5% vs. 7.3%) are closer, and they are lower than the comparison states.“
- Lane Sharing as a Motorcycle Safety Practice; A Further Evaluation – another paper by Steve Guderian, a follow-up to Lane Sharing: A Global Solution for Motorcycle Safety.
- Motorcycle Industry Council Position on Lane Splitting (PDF) – Official position statement in support of lane splitting issued by the MIC in 2011. “In full consideration of the risks and benefits of lane splitting, the Motorcycle Industry Council supports state laws that allow lane splitting under reasonable restrictions.” Includes lane splitting guidelines that are similar to the CHP guidelines, although less specific and a bit more lenient.
From The California Highway Patrol
- CHP Lane Splitting Guidelines – The original California Highway Patrol Lane Splitting General Guidelines: “Lane splitting in a safe and prudent manner is not illegal in the state of California.”

From the American Motorcyclist Association
- Lane Splitting Position Statement – “Given the ongoing success of lane splitting in California and the recent enthusiasm for lane splitting and/or filtering in other states, the AMA endorses these practices and will assist groups and individuals working to bring legal lane splitting and/or filtering to their states.”
- State motorcycle laws – comprehensive AMA resource page with motorcycle laws – including lane splitting – by state. Includes on- and off-road information.
- Pro-splitting articles in American Motorcyclist magazine – the fine folks at the AMA have provided us PDFs of some great articles in the members-only AMA mag.

- National Highway Traffic Safety Administration lane splitting issue statement – “Although lane splitting is allowed in just a few areas of the United States, notably California, it appears to be worthy of further study because it offers a means of reducing congestion in addition to possible safety benefits. It is widely used in many other countries.”
