Does anyone remember? Harry Hurt and his crew investigated in depth 899 motorcycle accidents im Los Angeles. I have a copy of MOTORCYLIST Aug 1979 which mentions some of the highlights of that 174 page report.
Harry quoted back then " The average crash impact speed is about 20 mph but that's enough to splatter your head " A further quote from Hurt mentions that (back then) a helmet would take a 1,000 g hit and reduce it to 150 g's (400 g's results in a mild concussion) In head impact accidents , the helmet prevented or attenuated injuries 80.9% of the time. Only four injuries were reported caused by helmets, none serious.
Left turns in front of motorcycles accounted for a majority of accidents, (almost 75% of car motorcycle accidents).
Almost half of single vehicle accidents fatalities involved alcohol levels of .04 to .05.
Eye contact is deadly, don't depend on it.
The median time from departure to an accident was less than six minutes.
The median time for initiating a response to a situation is 1.8 seconds. A rider must detect, decide, and react to a situation in 2 seconds.
92% of riders involved in accidents had no formal training.
In 73.2 % of the 899 cases, the riders had no eye protection at all.
40.9% of the cases involved inattention on the part of the rider.
Just a sample. Lots of good info in there and it still applies today. Of course back then cell phones and texting weren't around.

I like the overview. I've never seen the Hurt Report before, I've read about it being referenced. I think actually reading the entire document might be interesting. I'll have to try to order a copy.
Interesting.
Bet that is a big thick technical read in its entirety.

Glad I sparked some interest. Good reading especially the conclusions.

I'm more interested in the raw data from which he drew the conclusions.
I wonder if they've put those 2 volumes on CD yet? The price they're listing looks like 90bucks for both halves which seems a bit high for a little pleasure reading.
Hmmm.
I'm going to have to think about that one. Yup, I'm glad you sparked my thinker to remember this one.

What does this mean? It means that you can't assume they see you or can judge your approach speed just because they seem to be looking you in the eyes. |

I don't want to start an argument and I certainly don't want to imply that all motorcycle accidents are avoidable.............but I believe that well over 90% of all motorcycle accidents could have been prevented if the motorcyclist was more attentive, better trained, less reckless, more visable, AND SOBER! Having said that there are a lot of idiot cages out there that don't give a damn about a motorcycle. It is OUR job to ride like everyone is out to kill us and that is the way I ride. So far so good  |

I was thinking about things making IMPACT ON my eyes. OK, now that my head's on straight... I understand. |

So far so good I agree. I reckon just about the only accident we could avoid is a cow dropping on us from the sky. However we'd have to ride at about 5mph to avoid most accidents and the darn cow would still get us. |

Before I got older and supposedly wiser I'd tell anyone that would listen that accidents involving left turns in front of motorcycles were the riders fault. Not always true, BUT.
I see riders going through light controlled busy intersections blissfully looking "cool" , laid back, with their feet on the highway pegs and generally wearing doo rags.
Maybe I'm paranoid but I cover the front brake.

I also agree with covering the brakes at any intersection I cover the brakes and have a watchful eye out. Not saying that stupid cagers won,t pull out about five feet from you because they will.
Heck I had a friend who was at a intersection at a stop light that was busy rush hour!! A Semi truck pulled up behind him he thought nothing of it but the light turned green and traffic still had not moved but the trucker had forgot about the bike in front of him and ran him over well his bike because he jumped out of the way.
It takes a 110% of your attention out there while riding most of all in the city !!!!

Again well spoken solo1, it's no wonder you have had a long time of riding fun, smarter & wiser are the key words. Your not cool riding like your invincible, but I have to say riding a Harley does change your prospective a bit, don't know why it must be the (James Dean thing). Stay sharp, keen, ready to react, cover the brakes and watch everything around you, move if you have to, plan an escape route, slow down or be ready to gas it if need be, in general be a alert motorcycle rider because they are out to get you....and oh ya have fun too.

They say most accidents happen within one mile from your home. Did have one friend when i was in my teens killed at the end of the street on his MC. So i have finally moved a mile away from my home  |
