Title: What is it that hurts most bikers that do get hurt
Post by Oldfeller on 06/09/09 at 13:54:46

Food for thought and discussion.  This was a serious study done by a state that had enough accidents to cause them to analyze the data in a meaningful fashion.

============

In 2006 about 4,935 people were killed riding motorcycles of different kinds (see above). A major Motorcycle accident study analyzed information from thousands of accidents, drew conclusions about the causes and looked for ways people can avoid accidents. The "Motorcycle Accident Cause Factors and Identification of Countermeasures," was a study conducted by the University of Southern California, with funds from the National Highway Traffic Safety Administration, researcher Harry Hurt investigated nearly every aspect of 900 motorcycle accidents in the Los Angeles area. Additionally, Hurt and his staff analyzed 3,600 motorcycle traffic accident reports in the same geographic area. Below are some of the findings.


Motorcycle Accident Study findings:

1. Approximately three-fourths of these motorcycle accidents involved collision with another vehicle, which was most usually a passenger automobile.

2. Approximately one-fourth of these motorcycle accidents were single vehicle accidents involving the motorcycle colliding with the roadway or some fixed object in the environment.

3. Vehicle failure accounted for less than 3% of these motorcycle accidents, and most of those were single vehicle accidents where control was lost due to a puncture flat.

4. In the single vehicle accidents, motorcycle rider error was present as the accident precipitating factor in about two-thirds of the cases, with the typical error being a slide out and fall due to over braking or running wide on a curve due to excess speed or under-cornering.

5. Roadway defects (pavement ridges, potholes, etc.) were the accident cause in 2% of the accidents; animal involvement was 1% of the accidents.

6. In the multiple vehicle accidents, the driver of the other vehicle violated the motorcycle right-of-way and caused the accident in two-thirds of those accidents.

7. The failure of motorists to detect and recognize motorcycles in traffic is the predominating cause of motorcycle accidents. The driver of the other vehicle involved in collision with the motorcycle did not see the motorcycle before the collision, or did not see the motorcycle until too late to avoid the collision.

8. Deliberate hostile action by a motorist against a motorcycle rider is a rare accident cause. The most frequent accident configuration is the motorcycle proceeding straight then the automobile makes a left turn in front of the oncoming motorcycle.

9. Intersections are the most likely place for the motorcycle accident, with the other vehicle violating the motorcycle right-of-way, and often violating traffic controls.

10. Weather is not a factor in 98% of motorcycle accidents.

11. Most motorcycle accidents involve a short trip associated with shopping, errands, friends, entertainment or recreation, and the accident is likely to happen in a very short time close to the trip origin.

12. The view of the motorcycle or the other vehicle involved in the accident is limited by glare or obstructed by other vehicles in almost half of the multiple vehicle accidents.

13. Conspicuity of the motorcycle is a critical factor in the multiple vehicle accidents, and accident involvement is significantly reduced by the use of motorcycle headlamps (on in daylight) and the wearing of high visibility yellow, orange or bright red jackets. (Note: the statistics which have just been released here in Australia - August 1996, DO NOT SHOW that "Lights on" legislation has worked!)

14. Fuel system leaks and spills were present in 62% of the motorcycle accidents in the post-crash phase. This represents an undue hazard for fire.

15. The median pre-crash speed was 29.8 mph, and the median crash speed was 21.5 mph, and the one-in-a-thousand crash speed is approximately 86 mph.

16. The typical motorcycle pre-crash lines-of-sight to the traffic hazard portray no contribution of the limits of peripheral vision; more than three- fourths of all accident hazards are within 45 degrees of either side of straight ahead.

17. Conspicuity of the motorcycle is most critical for the frontal surfaces of the motorcycle and rider.

18. defects related to accident causation are rare and likely to be due to deficient or defective maintenance.

19. Motorcycle riders between the ages of 16 and 24 are significantly over-represented in accidents; motorcycle riders between the ages of 30 and 50 are significantly under represented. Although the majority of the accident-involved motorcycle riders are male (96%), the female motorcycle riders are significantly over represented in the accident data.

20. Craftsmen, laborers, and students comprise most of the accident-involved motorcycle riders. Professionals, sales workers, and craftsmen are under represented and laborers, students and unemployed are over- represented in the accidents.

21. Motorcycle riders with previous recent traffic citations and accidents are over represented in the accident data.

22. The motorcycle riders involved in accidents are essentially without training; 92% were self-taught or learned from family or friends. Motorcycle rider training experience reduces accident involvement and is related to reduced injuries in the event of accidents.

23. More than half of the accident-involved motorcycle riders had less than 5 months experience on the accident motorcycle, although the total street riding experience was almost 3 years. Motorcycle riders with dirt bike experience are significantly under represented in the accident data.

24. Lack of attention to the driving task is a common factor for the motorcyclist in an accident.

25. Almost half of the fatal accidents show alcohol involvement.

26. Motorcycle riders in these accidents showed significant collision avoidance problems. Most riders would over brake and skid the rear wheel, and under brake the front wheel greatly reducing collision avoidance deceleration. The ability to counter steer and swerve was essentially absent.

27. The typical motorcycle accident allows the motorcyclist just less than 2 seconds to complete all collision avoidance action.

28. Passenger-carrying motorcycles are not over represented in the accident area.

29. The driver of the other vehicles involved in collision with the motorcycle are not distinguished from other accident populations except that the ages of 20 to 29, and beyond 65 are over represented. Also, these drivers are generally unfamiliar with motorcycles.

30. The large displacement motorcycles are under represented in accidents but they are associated with higher injury severity when involved in accidents.

31. Any effect of motorcycle color on accident involvement is not determinable from these data, but is expected to be insignificant because the frontal surfaces are most often presented to the other vehicle involved in the collision.

32. Motorcycles equipped with fairings and windshields are under represented in accidents, most likely because of the contribution to conspicuity and the association with more experienced and trained riders.

33. Motorcycle riders in these accidents were significantly without motorcycle license, without any license, or with license revoked.

34. Motorcycle modifications such as those associated with the semi-chopper or cafe racer are definitely over represented in accidents.

35. The likelihood of injury is extremely high in these motorcycle accidents-98% of the multiple vehicle collisions and 96% of the single vehicle accidents resulted in some kind of injury to the motorcycle rider; 45% resulted in more than a minor injury.

36. Half of the injuries to the somatic regions were to the ankle-foot, lower leg, knee, and thigh-upper leg.

37. Crash bars are not an effective injury countermeasure; the reduction of injury to the ankle-foot is balanced by increase of injury to the thigh-upper leg, knee, and lower leg.

38.The use of heavy boots, jacket, gloves, etc., is effective in preventing or reducing abrasions and lacerations, which are frequent but rarely severe injuries.

39. Groin injuries were sustained by the motorcyclist in at least 13% of the accidents, which typified by multiple vehicle collision in frontal impact at higher than average speed.

40. Injury severity increases with speed, alcohol involvement and motorcycle size.

41. Seventy-three percent of the accident-involved motorcycle riders used no eye protection, and it is likely that the wind on the unprotected eyes contributed in impairment of vision which delayed hazard detection.

42. Approximately 50% of the motorcycle riders in traffic were using safety helmets but only 40% of the accident-involved motorcycle riders were wearing helmets at the time of the accident.

43. Voluntary safety helmet use by those accident-involved motorcycle riders was lowest for untrained, uneducated, young motorcycle riders on hot days and short trips.

44. The most deadly injuries to the accident victims were injuries to the chest and head.

45. The use of the safety helmet is the single critical factor in the prevention of reduction of head injury; the safety helmet which complies with FMVSS 218 is a significantly effective injury countermeasure.

46. Safety helmet use caused no attenuation of critical traffic sounds, no limitation of pre crash visual field, and no fatigue or loss of attention; no element of accident causation was related to helmet use.

Great article, thanx - IT'S ALL TRUE!  


- My first accident at 15 was on a nasty CURVE on a dirtbike. Mild accident. Close to home.

- DIRTBIKE experience at a young age, definitely gives you good reflexes for life.

- My second accident was when a car u-turned in front of me. Mild accident. Close to work.

- My third accident was when a car blew a red light and hit my front wheel. Medium accident. Close to home.


And this study is the reason why I run an OPEN EXHAUST that
makes a racket (probably illegal too) that everyone hates, but
that everyone hears and I'M STILL HERE, so come and fine me.


-----------------------------------------------------------------------

As some of you know I live between 2 countries:

In GERMANY (1) there are truly few accidents and most regard
speed/reckless driving, animals on the road and road-guards.
In EUROPE road-guards frequently cut fallen riders in half,
a HUGE issue right now, specially in SPAIN.

And in MEXICO (2) most accidents occur due to cars ignoring
road rules and killing riders ...and of course children (9-15 y/o)
killing themselves on a daily basis on their friggin' scooters in
traffic.

-----------------------------------------------------------------------

Obsolete? maybe.

I think basically the ONE TENDENCY that has changed today is
the wide availability of motorcycles to the unexperienced masses.

Darn.... can't find it......  

I read a report from PA dept of Transportation that said in 2006 (or was it 2007?) there was a decrease in MC accidents, ( vaguely recall 17%) even though there was a increase in MC's on the road (titled, registared & insured).

I understand Verslagen's point (old statistics) but must agree with Stimpy.

In my case, I finally got my moped at 17+++ y.o. (three months to 18, can you believe it ?)
Still, it was souped up in a wily manner shortly after running in...

1st accident at 18, took a hairpin too fast, the bike ended up in an olive grove below the hairpin, I...just scooted and got to stay on the road... ::)

2nd accident at 18++ (450cc Ducati), dropped 2nd=>1st on a hairpin, when I opened up the gas the bike popped such a wheelie we tipped back and over  ;D

3rd accident well over age 30, in one case in a hairpin (dang hairpins!) in a mountain village, old lady washing the porch threw a bucket of soapy water at me... serendipity?  >:(

4th accident in town, 650cc BMW boxer twin, delivery kid ran a red light and I hit him square in the leg, he walked but his bike was bent 90º, and i fell down and almost broke my hipbone... :P

5th accident, I was riding the Savage, stupid overage grey yuppie jogging and listening to iPod, decides to cross the road as I ride by, OEM Disneyland beephorn not much use... he even insisted I call an ambulance for him...
"why an ambulance? I haven't hit you with a baseball bat... yet..."
:D

Anyway, I have my own special strategy for avoiding accidents...

I use a yellow headlight bulb

http://www.plasmaglow.com/catalog/images/headlights_yellow_big.jpg

It's much better than one of those odd blinkety blink headlight jiddery things... and yellow is remarkably visible even in twilight when everybody should have their lights on...

...in a universe of white headlights, yellow stand out.

8-)

PS A few traffic cops flagged me down, insisted yellow wasn't legal.
I just pull off my helmet and show them the ugly scar under my jawbone (cancer op at 25 y.o. actually)
and say "one is enough, Officer, I;d rather be seen and fined than not seen and driven over..."
::)
They somehow always  see my point and wave me away.
BUT
I behave... ;)

PS looky what I found... talk about accident prevention...

W/o quantitative numbers, I'm gonna say that this statement is unqualified.  There is a segment of the population that does not tolerate any drinking whatsoever.  These poor saps may have had a beer yesterday and it still showed up in their body.  So 'aha' that devil alcohol was involved.  Now if they were all legally drunk or had a beer that day, then I'll accept the statement.

When one examines the vehicles on the road, one notices right away that the vast majority of vehicles are cars and trucks, not motorcycles. That being the case, one would EXPECT that the greatest number of motorcycle crashes would involve cars or trucks. Helmet or no, the motorcyclist is likely to sustain injury requiring medical treatment. Other drivers are inevitably going to say they didn't see the motorcyclist, and it is likely true. However, they will say the same thing about the other car they hit, and it is still likely true. Consider - even a fool is unlikely to deliberately drive into another vehicle, given any chance at all to avoid a crash.

The observation was made that high percentages of motorcyclists are untrained, or self-trained. That is probably true of auto drivers as well, so it becomes a non-distinguishing factor. How many of us have taken at least the basic MSF course (or equivalent)? Remember that the Driver's Ed classes in school are among the first to be cut when budget reductions happen, and the school systems never did offer motorcycle training.

I also take issue with use of the word "accident." I do not believe that any vehicle crash in which one or other of the drivers made a mistake or violated a law is an "accident." After all, if it were an "accident" no one would be at fault and liability insurance would be unneeded.

The Hurt report was very well done, and no major report on motorcycle safety has been done in the U.S. since then, 1976 to 1981.  There have been excellent European reports but they're not exactly relevant to U.S. conditions.

Agreed, the MSF classes are very poor but better than nothing.  I just got my ERC card.  How one self-trains is critical.  If one reads David L. Hough's books, Keith Code's books, and James Davis' web site (http://www.msgroup.org/default.aspx), and practices the exercises they describe, one can likely do well.  Without this info, riders will continue to turn wide because they do not increase the countersteering pressure, or will crash from a gusting side wind because they turn the wrong way, or use too much rear brake and crash, or believe that laying the bike down is the best defensive maneuver when a crash is imminent, or run into trouble because they're looking at the trouble, not looking where they need to go...and many other errors, some of which Keith Code calls Survival Reactions which are natural and the wrong thing to do.

I thought that what hurts is when your girl runs off with the guy down the street cause he has a Harley.
Or maybe since most accidents are likely to happen within 15 mile of where I live, maybe I should move.
Or I could just take steps to insure that other drivers are more polite.

The comments about most crashes happening close to home and on short rides is undoubtedly true. Left unmentioned is that most riding is on short rides and close to home. That is also true for other vehicles. Few people go on long drives every day. Most driving is to the local store, or to the job, or to school. Few trips exceed a few miles, or an hour. If crashes occur more or less evenly, then it is to be expected that most of them happen close to home.

I agree that the MSF course is not especially good. I suspect that many who take it do so in order to avoid having to take the driving test at the Department of Motor Vehicles rather than because they expect to learn anything useful. At least one article has claimed that, after six months or so, the crash rate for MSF-trained riders pretty much equals the rate for self-trained riders. It is unclear whether the untrained manage to learn the needed skills, the MSF riders become overconfident, or some other factor is at work. The Hurt Report did mention the lack of counter-steering skills among the unschooled as a major factor, and that is a skill that some on this Forum seem to deride as well. Both countersteering and proper brake usage are at least mentioned by the MSF, and the MSF does not teach the ineffective technique of "laying it down."

There was mention that in most crashes the motorcyclist has no more than a couple of seconds to react. However, no mention was made that the drivers of cars have similar amounts of time. Auto drivers have a simpler problem in one sense, because a mistake in steering or braking doesn't make cars fall down. Motorcyclists, most of whom spend a lot more time behind the wheel than astride the bike, have to avoid the "stomp the brake" reaction automatic to cars and trucks. The time required to remember proper braking may well exceed the time available before the crash, especially if the rider has already locked up the rear brake.

Any study of crashes has an unavoidable bias built in. That is because the study does not - and cannot - look at non-crashes. Nor can it study minor unreported crashes in which the rider picks up the bike and continues on the trip. Thus the study cannot examine those behaviors which did not result in a crash. If successful methods cannot be compared to unsuccessful ones it isn't easy to draw conclusions.

I passed the MSF Experienced Rider Course Saturday.  Here's what I wrote about it (http://www.msgroup.org/forums/mtt/topic.asp?TOPIC_ID=10404).  There was no mention of countersteering either by the Rider Coaches nor in the book.  To the contrary, we were told to press the handlebar down in the direction of the intended turn rather than correct and effective countersteering to push it forward...push right to turn right, etc.  They didn't teach the best rear braking technique, either.  One should come off the rear brake progressively as the bike slows and more weight is transferred to the front--essential to avoid locking up the rear, skidding, and the likelihood of a low side crash.  

Most of the students in the ERC needed the card for motorcycle access to the nearby military facilities.  One needed it for their license, and I wanted the knowledge and coached practice.

Trick question---what's the easiest way to "lay 'er down?"  Lock the rear brake, of course.  Laying it down in front of an imminent crash has one simple result.  You hit the object going faster than if you'd stayed rubber-side-down.  Steel, plastic, leather, and flesh slide easier on pavement than rubber does.  The force of the impact varies the square of the speed.   If you could stay upright and brake down to, say, 5 mph before you crash vs. laying it down and skidding into the object at, say, 20 mph, you hit at 1/4 of the speed and 1/16th of the force (hit 16 times harder at 20 mph vs 5 mph).

I can appreciate the report section about dirt bike riders being under represented in accidents.

I’ve ridden motocrossers for years and still get out on my YZ250. (just went two weekends ago and got stuck in quicksand in Southern Missouri…who knew? Quicksand…really?) Anyway, I was cruising down Manchester a few weeks ago and some clown pulls out in front of me and before I knew it, I had popped up on the pegs, covered the clutch and brake and ………..did nothing. I waited while he slowly drifted back to where he should have been and then I got past him quickly. I didn’t slam on the brakes and get crushed from behind or swerve into another lane causing havoc.

I don’t think that is teachable in a class. I think I brought that over from racing. I think all of us pick up defensive riding skills in our own individual ways over time. I had not ridden street bikes for a long time until I started up again last year. My wife said she instantly could tell when driving in cars with me. She says I scan ahead and behind constantly and am hyper alert at intersections. Having said all that, anything could happen at any time.  You can lessen the odds, but you can’t eliminate them.

[/quote]
The MSF course I took actually covered a lot of this stuff pretty well.  The very strongly recommended NOT laying the bike down, for the above mentioned reasons.  You lose braking power, and what little control you have in a panic stop.

They also covered countersteer very well, in the classroom, and obstacle course.  They laid out a section of the course to mock-up having to swerve around a stopped vehicle; had to wait til you pass the first cone to start the swerve, and go outside the second set either to the left or right, set at the width of a truck.  You wouln't know if you were going left or right until you got right there, and they'd yell either one.  That way you can't think too far ahead.  Good countersteer practice I thought.

By the seat of their pants...which were often torn and shreaded and wet with blood from road rash.

Phelonius, that is AWESOME!

I know, but I had to sell it about 4 years ago to cover the cost of moving back home. You cannot believe how polite other drivers were when I took that thing out for a ride. No one ever left turned in front of me, no one ever tailgated me, no one ever crowded my lane. And when I come to a four way stop, even if they have the right of way, they smile, wave and motion me on through ahead of them.
Young girls loved it cause they didn't have to look at the back of my neck, they had their own supply of bugs to eat, and there has never been a better design of vehicle for drive by shootings.
It was once visited by more than 30 police officers in one day though.
BTW It offered a fun response to barking chasing dogs.

In 1935 Lt. Col. T.E. Lawrence (Lawrence of Arabia) died on a motorcycle in a failed swerve attempt.

He's pictured here on a Brough Superior SS100.

I took the msf course I wanted to learn from those that ride the right way and safe. At work there are self taught riders, been riding for years {there own words} come to work with there big bikes, flip flops, shorts, skull cap no gloves. Last year one of them took a corner a kid ran in front he hit the brakes went flying never knew he had to get the bike back up straight before braking. He was lost alot of skin sliding. Now he wears the right clothes and he took the MSF course.
