I must say that it's pretty disheartening to hear so frequently on the radio as I drive my son to school in the morning about a motorcycle accident on this freeway or that freeway. This morning some rider had to be air-lifted after an accident.

It seems to me that riding in morning rush hour is the most perilous for sure, but at the same time I'm thinking, with the way traffic jams up here in L.A. in the morning, how fast could they possibly be going?

I wonder what the statistics say about "time of accident" and what percentage are during rush house vs other times?

Our local insurance company always runs ads that say dawn or dusk is supposed to be the greatest risk due to this being the hardest time to see MC's. I guess this intuitively makes sense, as there are lots of studies that show around 70% of accidents involve the car not seeing and failing to yield right of way (mostly by turning left in front of the rider).

That said, I could never find any stats on time itself. In fact, the latest MAIDS report states 'Due to the absence of comparable exposure data, it was not possible to determine if any month, day of the week or time of the day was a risk factor.'

'how fast could they possibly be going?' This has always been a bit of a head scratcher for me as well. Our speed limit on surface streets is 50kph, and I never really see more than 55-65 in any kind of traffic. If you're looking out and pre-braking for sketchy intersections/cars your stopping distance to zero should be well under 60 feet. Unless you are carelessly speeding or not paying attention, it seems like it would be hard to get to fatal accident speeds in urban areas.

So according to this, it looks like about a quarter of moto accidents happen at rush hour. That is a significant chunk given the amount of hours in a day that represents.

OK. Still looking for the weekday stats, but there's some pretty interesting (and sobering) information available here http://www.iihs.org/iihs/topics/t/motorc...otorcycles

I took the following photos of a couple of screens from the site. The first shows time-of-day stats, but only for weekends. The second shows stats based on road type.





In Chicago, we don't seem to have as many bike crashes during rush-hour. Rather, the ones I see on TV happen just before the morning rush..like 4:00am-5:00am. It has long been my belief that many, if not most, of these riders are on their way home from a long night instead of on their way to work for an early start. (the preceding comment is based only on the poster's opinion not on any statistics whatsoever).

For me, commuting to work to downtown LA is a love/hate thing. You bring up a good point when you mention how fast could they possibly be going in traffic (not fast at all of course). But what's more important is the difference in speed between the cars and the motorcycles; the greater the difference in speed the more dangerous. The squid flying down the freeway going 75mph between cars (while traffic is only 5mph) is at greater risk than someone that's only going 10-15mph faster than traffic.

Riding in the middle of downtown LA rush hour is another story. Possibly even more difficult than freeway rush hour.

There are some interesting stats on the link that I posted. It seems "sport bike riders" are FOUR times more likely to be in a fatal accident. It makes sense when you think about it.
Good point, Mike. I NEVER lane split at more than about 15mph faster than traffic. Any faster than that and you are just asking for it!
"When a motorcycle is equipped with an antilock braking system (ABS), the risk of a fatal crash is reduced by 37 percent according to the IIHS. However, when motorcycles lack ABS, the risk for injury and death are considerably higher."

Wow, I'm glad I coughed up the extra dough for my DLX.

I've noticed here in Phoenix that motorcycle crashes tend to occur early, just as the morning rush is starting. That's a time when speeds are still high enough to do serious damage, coupled with a lot of traffic joining the flow. Not to mention generally groggy, distracted drivers.

My work buddy tasted pavement twice in a year's time (before deciding to turn in his helmet). Both times it was on the way into work at around 6:30 AM. Also, both times he was in the HOV lane moving considerably faster than adjoining traffic when a car suddenly shot left into his lane.

Flynrider, very unfortunate for your co-worker. I consider that scenario a "high alert" area. Anytime there is a large differential in speed (as I mentioned on my prior post, but different scenario in this case), be extra aware of cars jumping into your lane.

I also pay extra attention when lane splitting and I see a "pocket" for cars to jump into. Always be prepared for that to happen. I feel more comfortable in between two cars; it's the "pockets" I am more concerned about. Always have an escape route when you approach that situation.

After his first crash, I tried to explain that to him. Particularly that in that scenario he should keep to the left side of his lane and be ready to dodge into the left breakdown lane. After the second crash he figured that he may not survive the learning process and threw in the towel. I couldn't really argue with that.

For me, being in a fast moving lane next to slower traffic ranks right up there with approaching an intersection with left turning traffic, where alertness is concerned.

Well, it would certainly be different in LA than in rural America where I don't think there would be any particular traffic circumstances, like rush hour, that would raise the odds of accidents. We don't have HOV lanes, we don't have lane splitting, and we don't have as many people in a hurry to get someplace. I know I was in Cali twice last year, once on a motorcycle and once on a car, and both times I wondered if it would be worth it riding a motorcycle out there everyday. Never seen people change lanes like they do out there. Here people move ahead and then move parallel into an open spot. There people moved on a 45 degree angle and CREATED an open spot. We still have a large percentage of distracted drivers per population though engaged in texting or talking on cell phones.

Here I think dawn and dusk and deer pose a serious threat for motorcyclists.
