Motorcycle lane splitting: Better for riders, better for drivers, and safer than

sitting in traffic.

Recent research has confirmed what many motorcycle riders have known for years. "Lane splitting" – or riding in between lanes of traffic – obviously saves riders a lot of time, but it's also considerably safer than sitting in traffic and acting like a car, as long as it’s done within certain guidelines, and contrary to what many drivers think, it actually speeds up traffic for everyone else on the road. Riders, please pass this information on to the drivers in your lives.


It’s time for certain drivers to get these thoughts out of their heads: "lane splitting is queue jumping," "motorcyclists should have to wait in line like the rest of us," "riding in between cars is suicidal." While it’s illegal in most of the United States, it’s accepted in many other parts of the world, and evidence is mounting that lane splitting is safer for riders than sitting in traffic, and actually benefits car drivers as well as the riders themselves.
Safety benefits of lane splitting for motorcyclists

One of the key arguments against lane splitting is that, to many driver’s eyes, it seems like a dangerous practice. From a rider’s perspective, this couldn’t be further from the truth.


The most common type of accident on the road is a rear-ender. These make up 40 percent of all accidents in the United States, according to the National Highway Traffic Safety Administration. And while most of these are minor fender benders between car drivers, there’s really no such thing as a minor fender bender if someone slams into the back of a motorcycle. By splitting between lanes, riders are able to put a shell of slow or stopped traffic around their bikes and protect against the inattention of other road users.


In a recent Berkeley study undertaken with the California Highway Patrol’s assistance, 7,836 motorcycle crashes were examined closely, with some 1,163 of these crashes having occurred while the rider was lane splitting.
Riders who were splitting at the time of their accident were significantly less likely to be injured in every category than those who weren’t: 45 percent fewer head injuries, 21 percent fewer neck injuries, 32 percent fewer torso injuries, 12 percent fewer arm/leg injuries, and 55 percent fewer fatalities.


This is quite possibly because the majority of those splitting accidents happened at speeds between 1 and 30 mph (50 km/h). The data also shows that the safest way to lane split is to travel at less than 30 mph, and less than 10 mph above the speed of the surrounding traffic. Injury rates leap up in all categories when both of these conditions are violated.
Benefits of lane splitting for other road users

Lane splitting is an unspoken contract between riders and drivers. Riders don’t wait for stopped cars, and in return, they don’t make the cars wait for them. Where many drivers get it wrong is that they see lane splitting as "queue jumping" that will cause each car to go one further spot back in the queue. In truth, a filtering bike disappears from the queue altogether, the only time a motorcycle holds a car up is when it sits in traffic and acts like another car.


Filtering bikes work their way to the front of stopped traffic at red lights, and accelerate away much quicker than the cars around them. When they reach the next stoppage, they disappear again between the lanes and no car is held up.


Certainly, this is a good deal for the rider, who arrives much earlier than the car driver. But every filtering rider has a positive effect on traffic flow that benefits every other motorist. A 2012 Belgian study found that if just 10 percent of drivers were to switch to motorcycles and filter through traffic, travel times would decrease for the remaining car drivers by some eight minutes per journey. This benefit would not exist if motorcyclists ignored the inherent advantages of their smaller, narrower vehicles and sat in line like cars.


The same study found considerable environmental benefits to lane splitting. Not because bikes emit less carbon (many larger bikes are as bad as cars), but because every bike that lane splits actively reduces the amount of time every other vehicle on the road spends sitting in traffic jams.


So the next time a rider wriggles past you in traffic, remember that it’s a win-win. The rider is saving time and money, and looking after their own safety, but they’re also making everyone else’s journey faster. So give them some space, for your own sake.

And spare me the "But I've seen motorcyclists lane split at 100mph when traffic is stopped!" or "wheelies past stopped traffic at 60mph is dangerous!" comments. I don't ride like that, in fact, most people don't ride like that despite your opinion that ALL motorcyclists are a bunch of lawless hooligans who deserve to die. :colbert:
 
I think their statistics are a bit optimistic. I would contend that it is beneficial to lane split past the first few cars to get away from where people are slowing down into the heavy traffic and then queue. That would likely be the safest possible way.

I have no problem with bikers doing as they please as long as they don't run into my vehicle, I'm all good with them.
 
There are good bikers and bad bikers.

Some want to announce themselves by as much noise as possible.

Others are considerate.

Well said.

I've got 50+ years experience riding a motorcycle on the street and to allow myself to get into a situation where I'd feel safer lane splitting isn't going to happen. I can see why a person would need to ride his/her bike on something like a LA freeway but I ain't going to do it. The only place I'd ride my quiet little enduro on a freeway is in the right lane where I have a clear path to safety (no walls). Riding on California Freeways, the only place I could lane split legally is out in the desert with plenty of places to hide.

Lane splitting at 100mph while doing a wheelie is probably safer than texting while driving.
 
I have no problem with lane splitting. Unfortunately, the majority of lane splitters I see do so in an unsafe manner.

I agree with that.

I think lane splitters are crazy.

People already fail to see whole cars and trucks next to them...and just move over as if the other car doesn't exist.

If they can't see a Tahoe, they sure as hell won't see a Ducati. 🙂
 
In CA, lanesplitting is just part of the culture. In 5mph traffic, a motorcyclists is just doing a few miles an hour faster. And most people make a little room for them since most freeways have wide lanes. Except LA. LA has old freeways, and is just filthy.
 
I see plenty of safe lane splitting and the benefits are obvious when you see it in action. It's very common here in the bay area. Id be concerned about my own safety if I was a biker but that's up to them I guess...

Side note: Just don't expect sympathy or understanding if you have a super loud exhaust and rev your stupid bike up when driving between traffic. I know this isn't everyone but I swear it's about 25-50% of bikes here. This makes you a public nuisance and I imagine makes many people wish you'd crash and die. Loud pipes don't save lives. They make everyone hate you.

California is starting to crack down on illegal exhausts (and a vast majority of them are illegal). My bike has the stock exhaust with catalyst and I have no intention of changing it. The bike has plenty of power and sounds good as it is. Plus, removing the catalyst makes the exhaust smell much more.
 
I think sitting at the end of a jam is far more dangerous, myself. One of my high school friends was killed in California by a rear end accident. I think he was at a stop sign so it would not have helped him, but in traffic a simple fender bender for two cars could be a terrible tragedy for a motorcyclist.
 
My concern with lane splitting would be how other drivers would react to it. Cars don't expect someone to be in that spot. Somebody swerves to avoid something and you could be screwed.

I'd be willing to do a trial run on certain lower speed in-town routes to see how well it goes.

There's a lot of Harley riders around here that I swear are running straight pipes. Like you said, you can tell by the smell of the exhaust after they go by. I don't buy the safety argument because sport bikes aren't nearly as loud. In fairness, it's a problem with a lot of cars too. We've always had tuners around where I lived but recent growth has attracted a lot of ricers. They're not courteous about where and when they go for a rip. I always thought thrush mufflers weren't street legal. You're not being cool if your Civic sounds like a chainsaw.

I've heard some pretty loud exhausts on sport bikes too but it seems like the first mod every Harley owner does is scrap the quiet and legal exhaust and put on one that is ridiculously loud. Stock Harley's are not loud at all. I'm sure there is a lobby backed by aftermarket exhaust manufacturers fighting this law enforcement trend so Harley's will be spewing unburnt fuel and noise into the air for decades to come.
 
According to the study.
"LSM were also less likely to be rear-ended (Table 3) by another vehicle (2.7%) than were other motorcyclists (4.6%).
LSM, on the other hand, were much more likely to have rear-ended another vehicle (36.4%) than were other motorcyclists (14.9%)(Table 4)."

So safer from being rear ended, but worse in rear ending someone else. 31 out of 1163 safer from being rear ended. 423 out of 1163 less safe from rear ending someone else. Sounds safer to me...or not.

"It can also be seen that the motorcycle speed almost always exceeds the traffic speed, at times by a considerable margin."
Sounds safe to me.


Also that 40% rear end rate was for cars. Looks like the study rate was only a total of 4.3%.

Author massaging data to make a point and failing?

Getting rear ended on a motorcycle by a car is FAR more likely to cause injury than a motorcycle rear ending a car.

As the speed differential goes up the risk goes up. If you stay within 10-15mph of the speed of traffic around you it is fairly safe to lane split. I would give one bit of advice to anyone looking to do this though, remain alert and scan front wheels for vehicles looking to change lanes. Also, know the width of your bike and be prepared to stop if you aren't sure you can filter between two vehicles. I watch for bikes coming up from behind me when lane splitting too and will move over into a lane to wave faster riders past.

Another tip, if you're lane splitting, please do it in the left most lanes. Last week I was coming home from work and some dickhead (on a Harley) cut over from the lanes to my right into my lane to split and almost hit me. He didn't even know I was there until he cut me off. He gave me a sheepish wave after he did it. 🙄
 
There are good bikers and bad bikers.

Who's to say but Motorcycles are scary as hell. I've been riding Motorcycles for 43 years. Not that that I've owned and ridden other rides and have been hospitalized numerous times but I kept this one. Dropped her a few times in intersections, lane ways and parking lots but she's my Saint on the HWY and Winding Roads.

I DON'T LANE SPLIT with cars on Public Roads if I can avoid it but in a Motorcycle Race situation, Tack or Asphalt Roads to No Where, is another matter as long as there are NO CARS.

I'm 67 years old and have been a Motorcyclist's for 54 years and fortunately still alive. I still love to ride Motorcycles.

Wish you all the same.

It's dead because you say it's dead? 😵

It's dead because saying "when done in a safe manner it is safe" is stupid. True, it might be safe. But, how many riders are going to do it safely? About as many as car drivers who obey speed limits and use their turn signals every time.

We don't need a thread on this every couple months. We get it, you want to do it. Nobody else cares.
