I mostly split on the freeway.
If the traffic is stop and go, I split.
If it's moving along at a decent clip, say 40 MPH, I ride with traffic.

City streets, I usually only split if some moron is causing congestion with poor driving.

News article

A year-long California study of motorcycle lane-splitting has concluded the practice is no more dangerous than motorcycling in general, if the rider is traveling at speeds similar to or only slightly faster than the surrounding traffic.

The maneuver becomes more dangerous, however, when a motorcyclist is speeding or riding more than 10 miles per hour faster than the traffic the cyclist is passing.

Lane-splitting occurs when a motorcyclist passes other vehicles by riding between them along the lane line. California is the only state that does not ban the controversial practice, frowned on by many car drivers who consider it a safety hazard, and applauded by some motorcyclists who say they consider lane-splitting a safety tool that allows them to get out of risky situations.

Lane-splitting in California appears to be on the rise. The state Office of Traffic Safety study found 62 percent of motorcyclists say they lane-split on both freeways and other roads, a 7.5 increase over 2013. Seventy-five percent of riders between the ages of 18 and 24 report they lane-split on all roads, including freeways. Notably, the survey found that motorcyclists were splitting lanes at slightly slower speeds and in slightly slower traffic than the year before.

The lane-splitting crash study, conducted by the University of California, Berkeley, and commissioned by the California Highway Patrol and the state Office of Traffic Safety, also found that lane-splitters are less likely to be rear-ended by car drivers, but are more likely to rear-end other vehicles.

Lane-splitters had a greater chance of being involved in a crash during the morning and afternoon commute hours than motorcyclists who were not lane splitting. The study also found that lane-splitting cyclists who were involved in crashes typically wore safer helmets than motorcyclists as a whole.

“What we learned is, if you lane-split in a safe or prudent manner, it is no more dangerous than motorcycling in any other circumstance,” state Office of Traffic Safety spokesman Chris Cochran said. “If you are speeding or have a wide speed differential (with other traffic), that is where the fatalities came about.”

The study was conducted statewide by 80 law enforcement agencies who filled out a supplemental information sheet involving 8,262 motorcycle riders in collisions.

The study’s authors said the report, the first of its kind about lane-splitting, is limited in scope, and will be followed up by more detailed analysis, including looking at rider age, rider gender, motorcycle characteristics, and collision and roadway characteristics.

The CHP last year published written guidelines on when motorcyclists should or should not lane-split, suggesting riders should not travel more than 10 miles per hour faster than surrounding traffic, and should not lane-split at all if other vehicles are traveling faster than 30 miles per hour. The CHP took those guidelines down, however, after they were determined to be illegal regulations, because the CHP failed to go through the formal vetting process for regulation-making.

I split on the freeway, and I split at stops. I have seen too many cars/bikes rear ended by inattentive drivers while they sit helpless at a light or stop sign.

:thumbsup: Thanks for posting this Olds. Great study and great article.

I also lane split on the freeway when traffic is slow and at stops, I've been doing it for many years and I think that, when done in a prudent manner, it is safer than just riding along in your lane.

I don't ride but definitely support lane splitting and stay out of the way of bikers when they're trying to get by. Too bad so many bikers in this area will do 40+ over the surrounding cars or when traffic's already going 60. This gives it a bad rep locally. Also I HATE it when Harleys or loud sports bikes will rev up their engines when they are splitting. I want to get out and punch some jackass when he does that to me.

There we go, lane splitting is safe. Now they need to study safety sound (loud pipes) and high visibility chrome.

“What we learned is, if you lane-split in a safe or prudent manner, it is no more dangerous..."
Who'd a thunk it? If you drive in a safe or prudent manner, you don't increase the risk of serious injury? No way!


The problem is, quite a few people don't lane split in a safe manner. I've had guys blow by me during stopped traffic. And I don't mean guying 15mph, they were flying.

With that said, I wouldn't lane split due to the fact I already think everyone is a moron, and I am enclosed in a rather safe box of metal. I wouldn't add additional risk, even if it saved me a few minutes on a commute. I am never in that much of a hurry.

The problem with lane splitting is that you have these assholes thinking that it's a right, and that you have to move over to let them lane split while you're just stopped. Otherwise, they get hostile on you by either swerve into you as they pass, or look back in an intimidating manner, or acting as if they want to kick your fender as they zigzag by.

Tell me that doesn't happen.

Ya, there are jerks in every demographic. The only reasonable solution is for everyone to stay home and have Amazon bring everything. Never venture out and chance running into a jerk.

See, I don't see that as a problem, I see it as a solution. Darwinism at its finest.

Seriously though, what is the solution to idiots acting like idiots? BAN THEM!!! Or it... or whatever... except when it comes to guns, we can't ban those. :sneaky:

I've even seen times when they'll look over or look back cause two large pickup trucks were side by side and they couldn't get through even though it wasn't intentional.

I don't mind lane splitting but I'm seeing an increasingly number of motorcyclist who don't do it safely.

I'm in New York, where lane splitting is illegal.
Lane splitters here are different than what you would see elsewhere. If you see a lane splitter here you are likely seeing someone who could care less about laws or other people. While there are plenty of normal riders who lane split "properly" they are overshadowed by the douche brigade.
You have the biker boy generation flying though traffic. These morons are quick to pin the throttle in neutral at anything they decide is "disrespect" and punch a side mirror off.
You have the cruiser douches with open pipes who do all their middle aged best to strike an intimidating pose in all their post divorce glory.
You have the BMW brigade (s1000r excluded)...well usually these guys are alright, even if they are breaking the law they typically do lane splitting the right way.

I'd even dabble in it if traffic was backed up miles and it was hot out. Fortunately I commute by rail so I haven't had to deal with rush hour traffic in ages. If I hit a traffic jam its off hours and I'm patient. I'll stick it out.

The culture here doesn't really support lane splitting. To many pricks on the road. Trying to block your path or tossing crap out the window. I stopped lane splitting after the last time scrapping gum off my fairing and having someone try and hit me with coffee. Fortunately, as long as traffic is moving weaving in and out of the gaps works fine. Not as quick as lane splitting but usually enough to get past whatever is holding things up.

Summary - Lane splitting ok. NY'ers are pricks on the roads

In what world (or state) would he be going to jail? :confused:
I would assume any state in the Union.
Here, specifically is California.
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 upon the side of a vehicle available to moving traffic for a period of time longer than necessary to load or unload passengers.
Amended Ch. 162, Stats. 1963. Effective September 20, 1963.

Wow, OK then.

California. Why am I not surprised.

Who said that he was trying to kill someone? He just opened his door.

When done on the freeway with the intent of doing bodily harm, it's not just opening the door. Despite what criminal charges you would face, I know several fellows that would drag your ass out of the car and beat you to a bloody stump for doing that.

Sorry guys but without proving intent no one is getting charged with anything more than that misdemeanor. It may suck, but that's reality. All the guy has to do is play dumb and claim he didn't see the biker. Gonna be hard to prove otherwise. Perhaps that's something to consider. That and the fact that if someone did decide to do that, charging them with a more serious is hardly going to resurrect you.

Like I said before, you guys are way more trusting than me.
