CMSP Lane Splitting Guidelines issued

And he directly said "lane splitting is the way to go, it's safer." I only ask because in all the curriculum I've reviewed it's always treated like a rattlesnake...avoid it at all coasts.

Enchanter will probably chime in here with the Cali MSF official position.
 
He said "lane split to avoid rear enders which are the lion's share of car v. bike collisions." I take this to mean it's safer, because I trust my situational awareness and reflexes a lot more than someone else's. I've worked on them every day for years.

Could he have meant do it at stop lights? It's looks to me, no offense, that you heard what you wanted to hear. Escaping an impending rear end collision by evasion between cars is an accepted strategy.

Oh, and 6% of car/motorcycles accidents are being struck from behind. 77% happen between the 10 and 2 o'clock position. He may have been exaggerating for effect but he sounds like he was seriously off script and dead wrong about his numbers.


(An aside, if I were affiliated with the organization where you received that info I would be asking where and when you got this info in order to sort out what was said and potentially remediate the RC if necessary.)

Of course I heard what I want to hear. We all do. lol. I've been a cyclist for a long time before I was a motorcyclist. The sound of tires screeching to a halt behind you doesnt go away.

Correct me if I'm wrong but I believe you're referring to the Hurt Report, which states most of those 10-11-12-1-2-o'clock accidents occurred from a motorist not seeing a bike approaching them from the front. If you limit data of accidents between cars and bikes traveling in the same direction I wonder what you'd get.

According to the Hurt Study, 77% of two vehicle accidents occur in the 10, 11, 12, 1, and 2 o'clock positions of the motorcycle. The area behind the driver, accounts only for about 3% of impacts.

We see that drivers aren't just seeing motorcyclists, most of the time they aren't seeing them when they are approaching from the front.

I dont know where the 6% from behind comes from. This article says 3%, and not behind the motorcycle, but behind the "driver," which in this context I believe refers to the car.

Edit, scratch that:

On page ninety is what we're talking about, 77% is 11-2 o'clock. 3.4% is 6 o'clock. 6% is 4-8 o'clock. Still I'd like to know what that clock looks like when only viewing data about collisions between vehicles traveling in the same direction.

All cool by me. The reason I'm re-engaged here is because this is a useful, enlightening and productive conversation. I have no doubt that we need to hear from our resident numbers guru Datadan for good stats (it's his thing) and Enchanter to get the official Cali MSF scripting.

I'll defer to them.

Oh, if you ram you bike into anything, be it tree, car or pedestrian, that's an impact at your 12 o'clock.

Question: What about crossing solid white lines, yellow lines, or double yellow (like carpool lanes in SoCal)?
