Minnesota Lane Filtering - Coming 7/1/2025!

[r0ckrat]

I threw up a link, no more or less.

You threw up a link not related to the item initially stated, and quoted a line from another unrelated source.

In other places you incorrectly stated that there was a law that specified how splitting in California may be done, and stated that CHP and local agencies "broke their own laws" about splitting.

That's misinformation. Misinformation, multiple times, in different ways, always casting splitting in a negative way.

Why are you attacking the messenger for the message in the linked article?. It's not MY study nor results.

I'm not attacking the messenger, I'm disputing the message, and the message provided was not in the linked "article" that I could find through a cursory glance. The "article" was not related to the study, but was the CHP's safety tips for motorcycle riders. If the study was mentioned on that page, someone would have to look hard to find it. When quoting a study, one normally provides a link to the study, not to a tenuously related (by being in the same general overall topic) website that has a mention of the study possibly buried in it.

Yep, just read the page and checked all links on the page. Nothing there whatsoever about the "2023 study by the University of California, Berkeley" that you say has a finding "that around 17% of motorcycle crashes were attributed to lane splitting."

OK, the points are made, enough sniping...

 

[r0ckrat]

I am unable to find a 2023 Berkeley report involving motorcycles, but the 2022 report paints a very different picture.

2022 SafeTREC Traffic Safety Fact Sheet: Motorcycle Safety | Safe Transportation Research and Education Center

safetrec.berkeley.edu

It primarily talks about fatal and serious injury events. And lane splitting is not mentioned at all.

Over two-thirds (67.2 percent) of motorcycle crash fatal injuries occurred in urban areas, compared to 32.3 percent on rural roads. Approximately 18.5 percent of travel took place on rural roads in 2020.

Over one-third (39.0 percent) of all motorcycle crash fatalities occurred on non-interstate principal arterials. The next most common locations for motorcycle crash fatalities were non-interstate minor arterials (26.7 percent) and non-interstate collectors (16.9 percent).


Primary Crash Factors of Motorcycle Fatal and Serious Injury Crashes
■ Unsafe speed (30.9 percent), followed by improper turning (22.2 percent), and right-of-way violations by automobiles (16.1 percent), were the most frequent primary crash factors for fatal and serious injury motorcycle crashes.

Two sources, one linked, the other a chp page. As I mentioned, call that bastion of liberalism university if you want further clarification on how they arrived at their findings. Just as simple as that. I simply provided what I found through a search of filtering.

You accused me of having an anti filtering mindset, nowhere have I given a personal opinion on filtering in this thread or even in this forum/. You've ASSumed something not even alluded to by me anywhere here.

Not happy with the links, provide your own sources about fatalities involving lane splitting. I'll wait as I'm just someone interested in the statistically analysis of the increased risk of filtering. Not from someone's personal opinion on whether THEY find it dangerous or not. It would appear, if the Berkely study is correct, that there's that 17% of overall motor deaths who died while filtering and that number doesn't change no matter whose fault the accident was does it?.

I misstated the law only because two motor officers in Ca. didn't provide accurate information who should know the law, they're motor officres

 

[r0ckrat]

There wasn't, and still isn't, a link to the 2023 study in your post.

 

[brownie0486]

I wasn't provided a link or it would have been included. Call Berkely if you have any further questions about their study.

But check this link out

Does Lane-Splitting Increase Motorcycle Accidents In California? | Lehr Law, APC

Here is an overview of lane splitting, including whether it plays a role in the number of motorcycle accidents in California.

www.lehrlawgroup.com

"Thus, lane splitting itself does not increase motorcycle accidents in California when done correctly. However, the majority of bikers in California do not follow the proper precautions and expert guidance on how to safely practice lane splitting, resulting in the nearly 20% of motorcycle accidents that are attributed to the behavior."

Take it for what it's worth or discount the above information.

The speed-differences-causing-more-consequential-accidents is why Minnesota's law has specific restrictions around how fast the motorcyclist and traffic can be moving while lane splitting.

From the 2022 Berkeley paper "Unsafe speed (30.9 percent)... [was one of] the most frequent primary crash factors for fatal and serious injury motorcycle crashes"

 

[kbasa]

Does it matter who's at fault when reporting numbers of collisions when filtering? I don't think it will matter one bit if you become part of those statistics.

Maybe lane splitting isn't for you. Your arguments are like the ones I get from non riders when I tell them I ride motorcycles.

If it's not a risk you're willing to assume, don't do that, but don't make that decision for me.

Sheesh.

Sheesh.

I'm arguing? That's rich. I"m simply looking for statistical analysis to whether splitting increases ones risks. I'm not looking for personal opinions, but the various research results have produced, if any, on increased risks. What I've discovered so far is splitting lanes isn't much if any more dangerous than not splitting, with the exception of the fact that most don't split per recommendations from chp which is 10 over the cagers speed and that appears to increase whatever risk of splitting is further.

What argument am I making throwing links up to studies from various sources? Again, I haven't stated a personal opinion here on splitting thus I fail to see the accusation of arguing as actually valid.

What I have noticed in this thread is that confirmed splitters are very sensitive to anything that suggests splitting increases a motors risk/s. I'd suggest not being so sensitive and willing to attack someone whose attempting to learn the added risks, if any, when splitting. At this point I have my answers, but certainly not from any members personal opinions stated here.

 

[Scott9999]

That relates to the amount of time spent and number of miles travelled in traffic...

There is also no information there about who is actually "at fault" in those collisions. I'd wager that 90% of those lane splitting incidents were vehicles making improper lane changes. I.e. not signaling, not checking their mirrors, not looking at what is right next to them, etc.

There is also a very long standing statistic that more than 50% of all collisions happen within 20 miles of home. Go figure...

Well, there's also the DUI factor. Way back a long, long time ago, I was a young lad working his way through college. I took a few law enforcement related courses for my job as a school police/safety (ok, ok, a GUARD) patrolling 43 schools in Orange County on the graveyard shift. (Applied and was accepted to two departments, which was a minor miracle, e.g. 600 applicants for four jobs, etc.., but opted for a Navy Commission instead. Anyhow ...). Short story long, back then their statistics had 50% to 60% of drivers were legally under the influence after 6pm, and the day long numbers were bad as well. Basically, every other traffic stop could involved drugs or alcohol, and I doubt that's changed much since.

I KNOW it hasn't in certain states that have legalized Marijuana and other drugs. (It's almost as bad in neighboring Idaho as in Washington state, too, because the state line and WA drug emporiums are a few minutes away.) We all occasionally lose focus, our vehicle wanders towards a white line, etc.., but 9 times out of 10, when I see that behavior, if I follow and observe the driver/rider closely, I can tell that they are under the influence of something. (My excuse for my own multiplying gaffs are because I'm under the influence of so many new technical toys, be it in my 2018 RT, or my newish 2022 Ford F-150 Lariat. I'll bet a WWII fighter pilot, if he were thrown into one of these things, would be bewildered by all of the controls and features!)

So, I kinda took this a bit off topic, but there are a 1001 different reasons a vehicle operator may have his/her rig "under-controlled", because they themselves aren't 100% fit. All the more reason to think twice on a motorcycle, and during ANY maneuvering. Just as the riskiest time to be in an aircraft is during take off and landing, the riskiest time on a bike are at times like merging, cornering, or splitting lanes between moving vehicles, OR, when other vehicles are doing the same (re: the infamous vehicle pulling out in front of a passing motorcycle, because the driver didn't "see" the bike coming).

 

[pauls1150]

I'm not sensitive! I'm not! I'm not!
Also a little off-topic: A few days ago, I was on a local busy surface street, four lanes each way, shortly before sundown, and I saw that the car in the lane to my left was drifting towards me. I couldn't tell if the driver was impaired or looking at some other feature (navigation?). So I gave him a blast of my horns to wake him (or her?) up. He got back into his lane, and gave me a looong blast back. Huh? I wasn't splitting, no need there, but there certainly was a threat to be handled.

I just read these study results from the above link. Nowhere does it mention lane splitting, filtering or any similar wording.

You're correct - two separate thoughts...

However, kind of interesting that they didn't include it, especially since they are CA based...

If it's not for you, don't do it. It's that simple.

Conspiracy theory style claims of unfounded motivations on the part of reporters isn't helpful and isn't data.

Is there data available is the question, and if there is, where is it? That's the million dollar question

Maybe this study of lane splitting safety from 2015 will eliminate the conjecture and add some facts to the conversation: https://www.ots.ca.gov/wp-content/u...Motorcycle-Lane-Splitting-and-Safety-2015.pdf

 

[brownie0486]

Your former LEO. Did you track whether a rider was lane splitting or not on traffic investigations? The data starts with collection and if it's not collected it's not measured.

I didn't run highway patrol. Appreciate that pdf, it's worth the read.

I think this quote from the study abstract says a lot:

"Lane-splitting appears to be a relatively safe motorcycle riding strategy if done in traffic moving at 50 MPH or less and if motorcyclists do not exceed the speed of other vehicles by more than 15 MPH."

Exactly my experience. Don't ride like a prat and you won't die. Note also the greatly lowered statistics for getting hit from behind in traffic by lane splitters.

California Lane Splitting Law Speed | Crockett Law Group

Gain clarity on the California lane splitting law speed regulations. Understand how speed limitations impact motorcycle lane splitting in California.

crockettlawgroup.com

"In revised 2022 guidelines, the California Highway Patrol updated speed limits again with a continued focus on prudent speed differentials versus surrounding traffic. The maximum speed threshold remains 50 mph for lane splitting. However, the differential dropped to 10 mph when traffic flows above 30 mph, and 5 mph when traffic is moving at 30 mph or less."

That's not the impression I got here from a few members. Anyone got more recent law changes on splitting in Ca.?
