Re: I have Doubts...

i'm sorry for your loss if you have a scaled diagram (the police should have measured to each of those evidence markings) and also the police report/crash reconstruction where is the scene (so a google map/aerial can be obtained) we can take a informal look and let you know what we think/what additi...

Re: What is the Change in Deceleration Rate in Relation to Velocity of Crashes?

Whereas i was hoping someone would join in so i don't monopolize the discussions, its been a month and you've gotten no response. So here's a quick first pass: : You ask: Is there a relationship between the deceleration rate of the crash time period and impact velocity of the vehicle? For example, m...

Re: NC collision with traffic signal sequence report.

I recommend you cut the police officer some slack. Realize they handle many cases, especially in a large city like Charlotte, and so you are but one of many cases. Be patient and understanding. Police officers have very different work schedules from the 'normal 9-5' so might be they are on a few day...

Re: Front Bumper damaged

CORRECTION: From the overhead it appears that prior to impact THE OTHER VEHICLE traveled approx 50 feet South. YOU TRAVELED approx 20 feet West?? with both starting from a stopped position that would mean THEY were in the intersection well before YOU were? In most states the responsibility is on the...

Re: Front Bumper damaged

more details required...what is the intersection? (so we can find on google maps and see distances, etc) And which way were you heading and which way were they headed prior to impact? The fact you could stop and they sheared across your front shows they were probably going faster than you at impact ...

Re: Does EDR informasjon and physical evidence on the car need to match each other 100%?

Rusty i'm with you on that. I'll add to what you said that the accuracy of EDR also depends on what year and model vehicle (so what EDR flavor) and what type of crash (um...was the EDR in the crush zone or moved etc involved?) It's a piece of the crash reconstruction puzzle but never the full pictur...
