You have FARO, but you are still learning equations on a green piece of paper??????

We have maybe ten in the county; most used by our TSD Detectives. FARO maps the scene, but we still need to find the hard values (…e.g….friction rates, initial/ending speeds, skid length, crush, etc.).

Curious though. Years ago my wife was in an auto accident. She was dead stopped on a road where people generally drive 50 in a 45 zone. 2 lanes each way divided by a grass strip. She comes around a corner and is stopped by a worker to allow a piece of heavy equipment to cross in a local construction zone. Broad daylight. No rain. Perfect visibility. Car behind her is Chevy pickup truck driven by young girl. Apparently her phone held her in fascination and she doesn't look up or touch the brakes as she rams my wife's car from behind. So no skid marks or anything as far as I am aware. The police report indicated she was moving at over 60 MPH on contact. How do they know or is this a "swag" based on the total destruction of my wife's car? |

So wait…. ….there were no skid marks at all?….not even rubber on the ground from your wife's car (…e.g. a strip, or strips of rubber left on the ground from her depressing the brakes when the impact occurred)? All you need are a few values to start working through the calculation. If the car has an EDR, you'll get speed values pre-crash, brake info, etc. There are also published co-efficient rates for all surfaces (…e.g…asphalt, cement, grass, sand, etc.) or you can use a drag sled to obtain those figures; all decimal. I can go on, but you can calculate it all. |

I have been leery of these devices ever since that girl back East (NH?, VT?) got charged with manslaughter when she lost control, hit a tree and her passenger was killed after hitting black ice. The EDR even showed she wasn't speeding or was traveling too fast for conditions. |

I'm not familiar with the EDR case you're referencing. I'll have to research it. Traveling too fast for the conditions can occur even if you're driving the prima facie limit, but other conditions render the posted speed too fast (…ex: driving the posted speed limit during heavy fog). |

In case it's not clear, I'm asking about skidmarks on the pavement...and not the driver's underwear/seat.....

ABS wouldn't be a factor since she is stationary with the brakes depressed. A collision like what you described wouldn't activate ABS. A collision while stationary leaves a dark scrub mark. |

I was thinking of the moving car's skidmarks, not the stopped car. For sure the stopped car would not go into ABS mode as long as the driver held the pedal firmly, and is probably a better measure of the moving vehicle's speed when you model a totally elastic collision between two known masses.....

Some of the experts in the field who teach accident reconstruction have run tests where they have driven cars into other motor vehicles, poles, brick walls, etc. One of the lead guys on this coast has been in over 3000 test accidents. |

When she had the wreck I was 3 miles away eating lunch after golf with a friend. A good Samaritan used her phone to call me and I was there when the ambulance arrived. Scared me to death seeing them put her on a backboard. One funny aspect of the story is to this day she doesn't believe me that I was there. Total blank for that period. |

Would be something to be in the courtroom when the judge throws her case out; and possibly her in jail. Guy has good instincts.

But pretty sure it's over. When she realizes she got dinged for court costs and the case will die until she pays them I'm guessing she'll go into a rage. If I was the guy I'd watch my 6, |

FYI, the Manhattan DA has decided to dismiss the murder charge against the bodega worker who stabbed an attacker.
FYI2, Rochester PD has now suspended the police investigator who handcuffed a working EMT at the hospital, while she was unloading a patient from her ambulance for emergency treatment. She allegedly bumped his patrol car when opening the ambulance's door at the dedicated ambulance unloading area, where the patrol car probably never should have been parked in the first place.....
