The vast majority of cagers are not in the way of a splitting moto. For those that are, a quick flash of your high beams should be all it takes. As others have noted, cars are not obligated to get out of your way.
Motorcycles are allowed to modulate their high/low beam headlight under CVC, at a rate of no more than 180 flashes per minute.

My Burgman 650 with the modulated headlight gets the split lane to open like Moses and the Red Sea, whereas my other bikes get much less favorable treatment. I don't consider it rude- I'll use any tactic I can to increase my likelihood of being observed.

I saw two LS party fouls yesterday within two minutes.

First one was a way high speed differential. Dude on a cruiser of some type. Not a huge one.

Both lanes were morphing at 5-10mph. Rider was going an estimated 30-35. I was shocked at how fast he was splitting. The LS Speeder would have zero shot of reacting to a fast lane changer IMO. Certainly a LEO would have had a case for a ticket for sure.

The second was maybe not a foul.. was an R1 splitting between lanes 2 & 3. His differential was OK I was in lane 3 and even though I watch my mirrors for bikes ( I saw him coming) many drivers don't unless they are in lane 1/2. Not all do then either of course.

This was on 101 So. before Fair Oaks so perhaps he was heading over to get off the freeway. I know that a lot of the lane 1/2 is screwed pavement or lack there off on 101 and I quickly glanced and confirmed this was not one of those spots.

I see plenty of riders do it right. The few that don't stand out for sure.

Thanks for clarifying the rules. I'm not in a place to check right now to confirm, but assuming you're right my opinion remains unchanged: Bright flashing lights are annoying to drivers and create a "holier than thou"/entitled dynamic out there that can result in backlash. But I consider splitting a privilege, not a right.

Cross-traffic hazards in the city

Somewhere up there ^ I wrote:
Don't enter an open intersection until you have a good view to potential threats. Approach slowly until you can see if there are crossing vehicles, pedestrians, or oncoming left-turners. If so, yield.
This is a city-street issue rather than a freeway issue, of course, but it can come in different ways. You're splitting traffic that has stopped at a mid-block crosswalk, at an uncontrolled intersection marked KEEP CLEAR, or at a yellow light you can easily beat. Then, as you enter the open area ahead of the stopped vehicles, you're suddenly dealing with a threat. It could be a car on a cross street or one turning left from an oncoming lane or a driveway on the right, or it could be a pedestrian or bicyclist.

My advice is to slow down as you approach the opening to give yourself time to spot and avoid whatever might enter your path. Further, I recommend that you yield to the threat. With a ped, it's a matter of law; with a vehicle, the law may be in your favor, but the law of undesirable consequences is not.

Here's a good example of just this kind of situation:

He covered it pretty well. Interesting that he didn’t comment on filtering / splitting with oncoming traffic.

More on cross-traffic hazards when splitting in town:

Yesterday, Sunday July 5, a rider was filtering on the double-yellow up to the red light here...



...when a pedestrian crossed from the right, between stopped vehicles. The ped was hit by the motorcycle, dislocating a hip. The rider fled after dumping his woman passenger (who apparently ratted him out).

Often, just keeping speed down and watching carefully for pedestrians will be enough. But with so many large vehicles on the road today, you sometimes won't be able to see the threat until it's too late. If there's a gap between stopped cars and you can't see over, around, or through the vehicle next to you, expect a threat until you're in a position to see that there isn't one.

More big-rig danger

Another tragic reminder about the danger of splitting alongside a big rig, this one in Los Angeles County.


looking west on westbound Imperial Highway at Shoemaker Ave in unincorporated Los Angeles County

A motorcyclist was splitting lanes 1-2 approaching the intersection on a red light, and he came to a stop between a tractor-trailer and another vehicle. Attempting to walk the motorcycle forward, he slipped and fell under the trailer's wheels. When the light turned green, the truck driver didn't see the fallen rider and accelerated ahead. The 60-something Whittier man was transported to the hospital but later died.

RIP, fellow rider and Whittierite.

Wow, that's one case when I was actually willing to split alongside a semi, except that I wouldn't do it if it was so tight I had to stop part way through to walk the bike past. Thanks for the reminders of unsafe practices to avoid.


Splitting isn't allowed where I live now and I don't know if I'll ever ride in California again, so I don't expect to run into that case in the future.

I appreciate your input and time spent doing this.

I have one item to add if you haven't spoken about it:
For newbies mainly, at 55mph you are traveling 80 feet per second!!
Let's half that, at 25mph you travel 40 feet, 40 FEET!! 1 second reaction time and 1 second to apply the brakes=80 feet= over 4 car lengths.
If you are lane splitting at that speed (which you do every day passing my truck) you will travel twice that before stopping. No way out, slow down, give yourself just a little extra time and space please.
Like it was mentioned in the first post, at slower speed you make up more time.

Thanks Dan! Just read all your posts and they were very insightful. Any advice on LS when group riding?

The easy answer is "don't" but that's not realistic. On a group ride, especially in the Bay Area, you're going to encounter traffic, and splitting may be the fastest and safest way through it.

However, don't forget the spacing requirement. Somewhere up there ^ I said something like "don't tailgate" and recommended following at least 2 seconds when splitting behind another bike.

The reason is that the trailing rider may not anticipate braking by the lead rider. When you're in front, you can probably predict an incursion by a driver eager to change lanes. You see the open space, you see him looking in that direction, you may even get half a blink from his turn signal, so you roll off or brake to avoid a crash. But the guy behind you doesn't have your vantage point, so he can't react to the anticipated incursion. Instead, he reacts to your reaction, and may not have enough time and space to avoid rear-ending you. And if there are more bikes behind him, the ugliness compounds.

This isn't just a theoretical possibility. I have several fatal crashes in my archives that happened this way, and it's often the lead rider who gets the worst of it. When splitting in a group, maintain your own space cushion and insist that the others do the same.

I would say "don't in groups larger than three bikes". Much more than that and it's tough to safely stay together. I like being number three in a group of three, though, because the first two tend to clear a path so that you have plenty of room. Same thing following a CHP bike.

While I generally agree with Scott, don't let your guard down if you are following someone. Expect the unexpected. I commonly observe cars moving to make room for the first rider and then, not anticipating another rider behind them, move back to their original position or even overcompensate and close the gap further.
